A summary of the meeting minutes is provided herein for your
information.

**TOPIC: A discussion on review and approval of the revised HPIC
Charter**

Ed Polz from Savannah River, submitted a revision to the HPIC Charter,
at the last HPIC meeting. He updated the HPIC Charter with those changes
as well as, added proposed changes. Listed below are the changes by
sections recommended by the HPIC, regarding the HPIC Charter.

**Scope **- Approved by the HPIC to revise "DOE" to read as "DOE
contractors".

"Majority vote rules with one vote allowed from each DOE facility" is to
be taken out of the scope and be included under "Membership".

"RCCC" needs to be taken out of the whole HPIC Charter.

**Membership** - Three types of HPIC memberships were created as
follows;

• [Voting member]{.underline} - Need to add, "Any one who wants to
participate on the HPIC committee will be a voting member of the HPIC,
but there will be only one representative per organization on the
committee who has the authority to vote on the issues of health physics
instrumentation. The HPIC can have two seats from the same organization
but that will need to go through an appeal process. A good justification
will be needed for additional voting seats at which time the HPIC will
vote on the appeal".

• [Participating member]{.underline} - A participating member would be
limited to participating but not have voting rights. Vendors would be
considered an observer. Are vendors going to be allowed to
observe/attend the HPIC meetings? The HPIC Home Page completely fulfills
the HPIC requirement to the Vendors as to the information provided by
the HPIC. The HPIC agreed the Vendors should be discluded as a
participating member and should have Vendors classed as observers.

Need to add a sub-heading as to "Non-member Participants" and change the
definition to read as "Observers will be welcome at the invitation by
the HPIC Chairperson, based on general consensus and approval of the
HPIC committee".

**Voting Rights** - The following is the recommended criteria to be a
voting HPIC member:

• Should have an RPP Program

• Historical HPIC members

• Number of instruments should not be considered (large facility vs. a
small facility)

• Susttained ability to attend/support HPIC

Those of you who are in attendance today that have been historically
been HPIC members will retain their membership rights for this meeting.
Those of you who are new and have attended only one or two meetings,
were asked to please abstain from voting at this time. The chairperson
will not vote while in that position. In the event of a tie, the
committee chairperson shall make the final deciding vote. At this
meeting there were 21 facilities who sent primary voters and 4
facilities with alternate voters. The voting members were identified by
placing gold colored placards written as a "HPIC Authorized Voter".
Placards were set in front of the "HPIC Authorized Voter" by the
secretary of the HPIC, Danise Gilsdorf.

**Member Rights **- All decisions of the HPIC shall be decided by vote
of the voting members present was discussed by the HPIC. It was proposed
by the HPIC to add "The HPIC will form a quorum if 2/3rds of the HPIC
members are present for voting".

**Rules of Conduct** -

A\) Holding a meeting twice a year versus once a year was discussed by
the HPIC. It was voted that the HPIC meet twice a year.

C\) Need to take out the word "committee" from Section C and D to read
as "HPIC" only.

E\) Currently the Charter reads; Procurement of standardized HP
instruments at each HPIC members facility will be encouraged "as much as
practical". "As much as practical" will be taken out and replaced with
"to the extent practicable". "Use of DOE purchase agreements for
standard instruments will be utilized as much as possible to achieve
this procurement". Needs to be changed to "Use of DOE purchase
agreements for HPIC recommended instruments will be utilized as much as
possible to achieve this procurement".

**HPIC Meetings** - "The HPIC chairperson shall submit an agenda to all
HPIC members a minimum of fifteen (15) working days prior to the next
meeting on issues to be addressed at that meeting". It was proposed by
the HPIC to change (15) working days to (30) working days.

**Voting** - The motion may be discussed with a time limit for
discussion of 15 minutes established if needed. Time shall be kept by
the chairperson or their designee. At the end of the 15 minute
discussion period a motion may be made by any member to continue the
discussion. It was proposed by the HPIC to change the discussion time
limit of 15 minutes to 30 minutes. At the end of the first 30 minute
discussion either table it or vote on it.

All other changes either added to the Draft Charter or red-lined were
approved by the HPIC.

**ACTION #1: [Danise Gilsdorf]{.underline} - Make changes as listed
above for the HPIC Charter and send out to the HPIC members. (Needs an
EM signature on the Charter.)**

**TOPIC: A report on utilization of the new Buy-on-Agreements in effect
for purchase of selected HP instruments given by Dale Snowder/LMITCO.**

The HPIC has been working for the past year on implementing a purchase
contract with manufacturers of selected Health Physics Instruments which
will allow participating DOE facilities to purchase them as needed. The
agreements are called "Buy-on-Agreements" or BOAs. They were designed to
meet all guidelines for fair and competitive bidding based on verified
and documented [performance testing]{.underline} and not specifically on
cost alone; thus BOA instrument purchases do not require sole source or
other normal procurement guidelines.

Additionally, the BOAs provide large cost savings by combining all
[participating]{.underline} DOE facilities' HP instrument purchases into
a single annual volume purchase with progressive discounts as the number
of purchased instruments increases. Bill Crownover and others of the
Procurement Branch of Lockheed-Martin Idaho Technologies (LMITCO) have
been instrumental in processing these agreements with the various HP
manufacturers and have successfully obtained all necessary signatures to
implement the BOAs as of June 16, 1995. The BOAs, which are actually
subcontracts, will be available to those HPIC members who advertised
their desire to participate in the BOAs at the past HPIC meetings. The
BOA contracts as well as the total discounted savings YTD are listed
below:

Only participating DOE and other Federal agencies listed in the BOA will
be allowed to participate in these BOAs at the present time. If you want
to be added to this list please contact Dale Snowder or Bill Crownover.
Phone numbers can be found on the attached attendance list. All
participation on the BOA is strictly **[voluntary]{.underline}**. You
may purchase HP instruments on your own or use the BOA for the discounts
and performance documentation it provides. The instruments for which
BOAs have been issued are those that are **[highly
recommended]{.underline}** by the HPIC for standardization.

When purchasing one of the selected HP instruments, the purchaser will
fill out a normal purchase requisition describing the instrument and
probes desired. Additionally, the purchaser should write on the
requisition the appropriate subcontract \# listed on the front of the
BOA agreement. It is possible that a procurement agent may choose not to
use the subcontract for some reason and you, as the purchaser, may have
to communicate the purpose and benefits of the BOA to the Purchasing
Agent. Processing of the BOA by your procurement agent should be
significantly simplified since no sole source justifications, low bidder
investigations, price negotiations, etc. should have to be initiated. It
is possible that labs/facilities can combine or coordinate their
purchases to coincide with the beginning of the calendar year to get the
discounts started. The more instruments purchased on the BOA, the higher
the discounts. Each HP instrument manufacturer has been contracted to
keep a detailed listing of how many instruments have been purchased on
their BOA on an annual basis and report these numbers to Bill Crownover
on a quarterly basis. There is a clause in the BOA that requires each
manufacture to provide in writing a description of any
modifications/changes to the instrument components which will/could
affect that instruments performance. Such notification must be provided
within 45 days of the design modification, and drawings of the
modifications provided to the customers within 90 days. Bill and Dale
are working on a manual of HPIC recommended instruments with the price
list and the BOAs all included as well as on the HPIC Home Page. Please
contact Dale, Snowder, Bill Crownover, or Gary LaBruyere for any
problems regarding the BOAs.

**ACTION \# 2 - [Dale Snowder]{.underline} - Need to attain information
on how the recovery costs are performed regarding the BOAs.**

**ACTION #3 - [Dale Snowder/Bill Crownover]{.underline} - Compile a
manual of HPIC recommended instruments with the price list and the BOAs
etc.**

**ACTION #4 - [Danise Gilsdorf]{.underline} - The BOAs need to be on the
HPIC Home Page. Get with Dave Hickman. Also, Mike Lewandowski/WIPP needs
hard copies of the BOAs sent to him.**

**TOPIC: A discussion on the recent progress on ANSI N323 issuance given
by Michelle Johnson/Battelle Northwest**

ANSI N323 is still in DRAFT form. Comments were received on ANSI N323A
Draft 8, dated Feb. 1996, back in April 1996, from several individuals
and were sent to Jack Selby, Chairperson of the Working Group for ANSI.
The updated Draft was revised July, 1996, Rev. 9. And is now divided
into four separate ANSI standards to better facilitate specific types of
instruments. These four standards are:

N323A - General Requirements & Portable Survey Instruments (still in
DRAFT form)

N323B - Low Range (near background) Survey Instruments

N323C - Air Monitoring Instruments

N323D - Installed & AC Powered Instruments

*The primary impact from comments submitted were*

• "General Requirements" applicable to all instrumentation was removed
from the scope. The Standard will be applicable only to portable
instrumentation, not to non-portable. The general requirements for
portable instruments are provided.

• A requirement for "maintenance procedures" was replaced with a less
formal "maintenance [instructions]{.underline}".

• "NIST traceability for calibration standards" was replaced with the
less restrictive requirement for traceability to "NIST [or other
international standards]{.underline}".

After all the comments were received, ANSI N323 was to be issued by the
end of 1996. As it sits now, there is not a time frame for the ANSI N323
to be issued. If you need help with interpretation of the new revised
ANSI, please call Jack Selby. Any HPIC comments can be sent to ANSI or
the Working Group. Michelle Johnson will report back to Jack Selby on
todays comments from the HPIC members regarding the ANSI standard. There
was a question asked as to what the heiarchy of ANSI N.323 is going to
become on the international scope of standards. It will be like a horse
race, everyone will want to get their standard in first.

**TOPIC: A discussion on draft of Periodic Acceptance Test policy for HP
instruments**

In ANSI N323 it states that "All instruments should be performance
tested to verify that they continue to meet the operational
requirements. Testing and calibration of instruments should be performed
under a group of controlled conditions called "standard test
conditions," (Table 1). Recalibration, maintenance, performance tests,
and functional tests should be conducted periodically to assure that the
instruments continue to meet the performance requirements for field
measurements. Performance tests should be repeated routinely because of
aging or replacement of components may affect the instrument's
performance". The HPIC asked as to how often it is required to go back
and redo testing on an instrument to ensure that the performance is
still suitable? The committee asked for decision on this and

the HPIC developed a draft listing of periodic acceptance tests that
should include, but is not limited to;

• Temperature

• Temperature Shock

• Humidity

• Radio Frequency

The number of units to be tested and frequency of tests is recommended
as follows:

• Number to test is 3 - 5 units for low \# instrument inventories (\<50)
or 10% of population for higher instrument inventories (\>50) on a
rotating annual basis for detailed ANSI N42.17A and ANSI N42.17C.

• It is recommended that MIL-STD 105D be used to identify additional lot
test requirements if abnormalities are found during the periodic
testing.

[NOTE]{.underline}: It is the recommendation of the HPIC that 100% of
instruments be tested during the normal calibration cycle for basic
tests including but not limited to; linearity, overrange, zero, and high
voltage.

Reporting Requirements:

• All results of periodic acceptance testing should be reported to the
HPIC through the HPIC Home Page to consolidate notifications, sharing of
technical data, and early detection/identification of potential problems
with instrument models in use at other facilities.

HPIC Comments:

MIL-STD 105D has been superseded with other copies. Mostly editorial
changes, the wording is still the same.

**ACTION \# 5: [Jeff Lively]{.underline} - Please send the superseded
copies to MIL-STD 105D to Dale Snowder.**

Not all of these tests are applicable to each site. There was a question
as to whether the HPIC needed to define a policy for performance tests
or to live by the ANSI Standard? It was voted by the HPIC to discuss the
periodic acceptance testing at the next HPIC meeting.

**TOPIC: A discussion on the status of Secondary Accredited Calibration
Labs**

NIST issued a draft standard in 1990. This standard basically identifies
the criteria for accreditation to a secondary lab as requested by NIST.
How many labs have applied or are pursuing a secondary accreditation? It
hasn't been a big issue as most facilities do not need to be accredited.
Oak Ridge National Lab (RadCal), Mound, and Rocky Flats are applying.
Battelle is already accredited in some irradiations.

**TOPIC: A review of the specification/grading sheets for the vendor
presentations**

• There are two separate grading sheets; one set is for Beta/Gamma
Portable Count-Rate Instruments; the second set is for Beta/Gamma
Stationary Count-Rate Instruments. Each set has been divided into
mandatory and desirable specifications.

• The grading sheets were provided to the vendor in advance with
requests to address each specification in the order on the grading
sheet.

• For grading, a scale of 1-5 was used for each specification. Grading
depended on how significant the spec. was to each facility's operation.

Grade of (0) - Vendor does not meet the specifications.

Grade of (1) - Vendor does not meet the specs. [but]{.underline} not an
essential spec.

Grade of (2) - Vendor meets the specs. partially, but [not]{.underline}
an essential spec.

Grade of (3) - Vendor meets the specs. partially, and is an essential
spec.

Grade of (4) - Vendor fully meets the specs but is [not]{.underline} an
essential spec.

Grade of (5) - Vendor fully meets the specs. and is essential spec.

• The Vendor presentations were not limited to the grading sheets. They
were opened up to the HPIC members for questioning.

• Competing vendors were not allowed to sit in on other Vendor
presentations.

• The information the Vendors give the HPIC and observers is
proprietary.

• All Mandatory requirements on the grading sheets were weighed heavily,
because they were basic requirements.

• The Spec sheets need to be added to the HPIC Home Page.

**ACTION \# 6: Gary LaBruyere - Please supply with the information
needed on the Spec Sheets to Dave Hickman for the HPIC Home Page.**

**TOPIC: A discussion on the Technical Basis Documents (TBDs) from Rocky
Flats**

Kaiser-Hill/Rocky Flats generated the following Technical Basis
Documents (TBDs) which are being distributed to the National Health
Physics Instrumentation Committee. The Technical Basis Document consists
of the purpose, description, operational capabilities and
specifications, why it met 10 CFR 835 requirements, selection criteria,
and testing on a specific instrument. The three signatures required on
the TBD constitutes it as site specific. Shared data will be listed as
"controlled copies". All these procedures will be updated as instrument
changes are made. Several HPIC member facilities must have a TBD for
justifying the use of their instruments and for auditing purposes. It
was suggested by the HPIC to have the TBDs thoroughly reviewed and to
create a dialog log on each procedure, as well as a checklist on the
Web. It was also suggested by the HPIC to use a disclaimer saying that
certain ANSI tests were simulated by Rocky Flats and that some
instruments which have TBDs have not been recommended for
standardization by the HPIC. If you are using the following instruments
and need a copy of the existing TBD, let Danise Gilsdorf know and she
will send you a copy.

**NRC Model ADM 300 Multi-functional Radiation, Detection and
Computation (Radiac)**

The NRC Model ADM 300 is a battery operated, self diagnostic,
multi-functional instrument used to locate and measure low and high
intensity radiation in alpha, beta, gamma, neutron, and x-radiations.
When in use, the ADM 300 can detect, measure, and digitally display
levels of radiation in a dose rate from 10 micro-roentgen (uR) (.001
milli-roentgen) to 1000 roentgens (R) per hour. It can measure, store,
and digitally display accumulated doses from 1 uR to 10,000 R. The
analog display covers 10 uR to

1000 R.

Features of the ADM 300 include:

• The ADM 300 has a liquid crystal display that shows three digits,
decimal point and unit of measure for dose rate/count rate or
accumulated dose. The display will also indicate low batteries and
faults.

• This instrument has an illuminated display for operating at night.

• Has an external probe attachment for increased and remote monitoring.

• It can be vehicle, commercial, or battery powered and mounted.

• The ADM 300 has an audible and visual alarm which can be set
independently for dose rate and accumulated dose.

• It is calibrated thru an RS-232 serial computer port. The sequence
code was a question (Earl Pollock will get back with the HPIC members on
the answer.) The keyboard is not static sensitive.

• Linearity is ± 5%.

• Accuracy is ± 10% of reading over entire range.

• Environmental testing as follows:

Temperature: Operating: -25°C to 50°C

Storage: -40°C to 60°C

Altitude: Operable from sea level to 10,000 ft.

Humidity: 0 to 100%

Shock/Vibration: Tested to MIL-STD-810

• The battery compartment is separated from the electronics and is leak
proof and sealed. The battery life is 100 hours extendable to in excess
of 200 hours using an external battery pack.

• It has a 1 yr. warranty on parts and labor.

• Training is available. Tech Manuals and schematics are provided.

• The ADM 300 is 4-18\" wide x 1-78\" high x 7-3/4\" long and weighs
less than 3 lbs. NRC offers several optional accessories:

--- A carrying strap, check source, external speakers, carrying case,
ear phones, bar code reader, and external smart probes.

The main meter of the ADM 300 contains two internal Geiger-Muller tubes
for radiation detection. One of the tubes is for low range gamma and
beta radiation. This tube detects at a range of 10 uR to 5 R per hour.
The other tube is for high range gamma radiation only, detecting at a

**TOPIC: An update on the DP Focus Group given by Paul Krumpe and Dave
Hickman**

Paul Krumpe discussed a Memo, Dated Oct. 31, 1996, Subject: Defense
programs technical position on the standardization and type testing of
radiological monitoring instrumentation used at Defense Programs
Facilities for radiation protection. Please read over, if you have any
comments or changes, let Paul Krumpe know.

The DP Focus Group is working at looking at all the instruments at the
DP sites. The unified approach to the implementation of the regulations
and sharing of operational and test data is expected to save DP from 1
to 4 million dollars during the next several years. The DP Focus Group
have meetings twice a year.

The DP Focus Group have been concentrating on type reduction,
consolidation, and cost efficiencies. They established a testing program
at Oak Ridge National Lab (ANSI 42.17). They are now working on the DP
Web Site.

Need to look at adding more TBD's, BOA information, and the HPIC
minutes, to the HPIC Web site. Reports and summaries for each test on
instruments evaluated should be added to the HPIC Web Site which would
reduce a lot of duplication of effort.

**TOPIC: A discussion on Standards-Based Instrument Testing and
Evaluation Program at Oak Ridge National Lab given by Peter Chiaro.**

Peter Chiaro is responsible for the "Standards-Based Instrument Testing
and Evaluation Program", at the Environmental Effects Laboratory, which
is still in the research end. The reports and summaries for each test on
instruments evaluated are available.The instruments evaluated and test
information is listed on the home page. The future plans is to support
the research and development of new equipment, installation of a screen
room for noise-less evaluations, and to improve data collection
methodology. For more information call:

**TOPIC: Discussion on the construction, calibration, and optimization
of the Bicron-NE DP6 given by BicronuNE**

The probe manual has recently been modified to clarify the best method
for defining the correct operating voltage for Dual Probes such as the
DP6. The methodology in the older test tended to guide the user into
setting an H.V. that was too high. This may have caused one or more of
these faults;

1\) High Beta Backgrounds

2\) Light Sensitivity

3\) Too many Beta's in Alpha Channel

4\) High Alpha Backgrounds

If you have experienced any of these problems they may be reduced or
eliminated by following the procedure from the newer manuals. The first
"DIP" method to be the most effective followed by efficiency checks for
both Alpha and Beta responses. These efficiencies will be slightly lower
but the MDA and reliability will be improved. The "DIP" method will
usually give a "Dip Curve".

**TOPIC: Growth of the HPIC**

**TOPIC: A discussion on the Bicron-NE RSO-50E given by Peter Chiaro**

Bicron replaced the RSO-5s and 50s with 50Es. Oak Ridge National Lab
evaluated 5 of the RSO-50Es and 4 out of 5 had temperature
susceptibility (no response when ambient temperature exceeded 93°F on 5
mR/hr range. Oak Ridge met with Bicron's engineering staff to discuss
the problem. Bicron discovered the cause and repaired the instruments.
The RSO-50Es were re-evaluated with acceptable results. Oak Ridge now
has 17 instruments in their inventory which includes 5 different
versions. Oak Ridge's recent observations were; occasionally oscillates
wildly from off-scale low to off-scale high. It typically returns to
normal when a latch is released, temperature is reduced below 30^0^C, or
switched off then on. This was identified in August, 1996. Bicron was
notified. After investigating, they found that other facilities had
returned instruments to Bicron with similar problems. The problem occurs
during temperature testing, during radiation calibration, when switched
on, and after mechanical shock. The initial theories were wet/dirty
high-impedance circuit, tight screw-to-chamber tolerances, and circuitry
design. Oak Ridge learned that the circuit design is acceptable. The
method used to ground chamber could be improved and using standoffs as
part of the power circuit may be a problem. Bicron used very close
tolerances between can screws and chamber, and/or may be moisture
related. The moisture could be picked up as air flows over or through
damp desiccant, the operational design makes desiccant critical. Bicron
made improvements to the high impedance section. They improved isolation
from environmental conditions, using 4 screws instead of 2 for the
chamber board mounting and trimmed screws inside of the can to increase
tolerances. Oak Ridge recommended the HPIC to obtain history of other
similar instruments for comparison and evaluate long-term stability of
the RSO-50E.

**[TOPIC:]{.underline} [A discussion on gas mixure analysis was given by
Pete Chairo]{.underline}**

Oak Ridge National Lab has been attempting to address temperature
sensitivity of gas-flow proportional detectors for use in the
environment. The objectives of this analysis was to decrease the
temperature sensitivity of the detector and to increase the reliability
of survey results. The evaluation process determined that is an increase
in back pressure could improve response, if another method could be used
to establish the high voltage setting. They evaluated different back
pressures, high voltage settings and different gas mixtures, such as
P-10, P-5, and 80/20.

The *Alpha* Results:

P-10

• Significant over-response (breakdown) at temperatures above 20^0^C

• Non-linear

P-5

• Over-response at temperatures above 40^0^C

• More linear than P-10

80/20

• No over-response observed

• Linear effects

The *Beta* Results:

P-10

• Linear effects until breakdown at 50^0^C

• Relatively flat slope

P-5

• No breadowns observed

• Linear

• Greatest slope of three gases evaluated

80/20

• No breakdowns observed

• Linear

The *Gamma* Results:

P1-, P-5, 80/20

• No breakdowns observed

• Linear

• Each gas mixture had equivalent slopes

The bias compensation was:

Can temperature sensitivity be reduced through adjustment of the
detector's bias?

Possibility depends upon:

• linearity of the temperature effect

• gas mixture used

Evaluated P-100

• evaluating P05 and 80/20

The evaluation Process was:

Stabilize the detector at 22°C and establish bias (high voltage) set
point

Change ambient temperature and stabilize

Adjust voltage to bring average response to within 15% of the average
22°C response

The compensation results were:

Adjusting the detector bias decreased temperature sensitivity

Less dependent on the type of radiation

Improved counting reliability

What's next?

Complete the gas mixture analysis

Depending on the analysis

• Develop an interface box

--- Automatically adjust high voltage based on gas temperature

• Replace gas with another, less sensitive mixture

Try to keep the instrument design changes to a minimum

**TOPIC: A discussion on Radon Thoron Monitoring instruments by Riasp
Medora/Fluor Daniel Fernald**

1\) CFR's are now requiring a work place for Radon-Thoron Monitoring -
this becomes Price-Anderson ACT enforceable.

2\) DOE has lost Radon/Thoron calibration capabilities.

3\) A question was raised about how other HPIC members calibrated
Radon/Thoron instruments.

4\) EPA Nevada can calibrate some instruments.

5\) Jim Bruner/WASTREN, notified the HPIC members that Grand Junction
had locked the doors on the Radon Calibration Lab., but could possibly
re-open if need was sufficiant.

6\) The HPIC members need to define DOE's over all need for calibration
on Radon/Thoron instrument then present findings at the next HPIC
meeting.

**TOPIC: Location for the next proposed HPIC Meeting**

(1st choice) Santa Fe, New Mexico

(2nd choice) Williamsburg, Virginia

(3rd choice) Charleston, South Carolina

**[TOPIC:]{.underline} [Date of the next proposed HPIC
Meeting]{.underline}**

(1st choice) May 5, 1997
