The calibration screen can be accessed from the front “Dose” screen by pressing“Setup” to access the “Dose Setup” screen and then by pressing “Calibrate”.
Two calibration methods are provided. “Auto calibration” requires a Cs-137 source
and automatically finds the centroid of two lines to provide a calibration.
Alternatively, a “manual” calibration can be performed using any available gamma
ray sources.
Auto Calibration
1) Point the probe at a Cs-137 calibration
source and press the ‘Automatic’ button.
Pressing ‘Automatic’ will clear all the existing
points from the previous calibration.

2) After the acquisition has completed theoperator will be given the option to use thecalibrated values.
Press “ok” to apply the new calibration.

8

Manual Calibration
Calibrations are generally performed with sealed
sources such as:
SourceGamma-ray energy

241

Am

60 keV

137

Cs

662 keV

Other sources can be used or added if
available. However, a minimum of two gamma
rays must be used for an adequate calibration.
3) Place the source in front of the detector andpress “Manual”.

4) Once sufficient data has been collected,press “Stop” to finish the acquisition andcontinue.
Note that the horizontal axis of the spectrum isin detector channel number.

5) The “Energy Selection” screen will be
displayed.
Move the cursor to the known peak position.
A single tap with the stylus will position the
cursor. To drag the cursor, not the graph, holdthe stylus stationary on the graph for 1s or morethen move the cursor.

96) Use the + and – buttons to zoom in/out on
the peak of interest. The peak can be centredon the screen by dragging with the stylus to theright or left.
Zooming in can also be achieved by double
tapping the graph.
Zooming out by holding the stylus stationary on
the graph for 1s or more and then releasing.
The peak can also be moved by using a fast
swipe with the stylus on the graph.

7) Place the green cursor line on the centroid of
the peak relating to the source and press“Assign”.

8) The channel number for the cursor position
will be displayed. If this is in the correct place
select “OK”. If not, adjust the value until thecentroid is found.

109) Enter the corresponding energy of the peakin keV, then press “OK”.

10) The “Calibration” screen will be displayed.
The ‘Repeat’ button allows multiple peaks fromthe same measurement to be used, or steps 6
to 12 can be repeated for a second source.
A straight line is fitted through the calibration
points and the calibrated values used in the2device are displayed in the lower box. The R
value measures the quality of the fit and should
be close to 1 for a good calibration.
To remove any calibration values select them inthe list and press the delete button.

11) Pressing “Graph” displays a graph of thecalibration points and the straight line fit. Thisgraph is useful for identifying errors in thecalibration points.
Pressing back returns to the calibration screen.

11Section 5: Stored backgroundThe device uses a stored background spectrum as a reference in somealgorithms.The spectrum can be accessed from the front “Dose” screen by pressing“Setup” to access the “Dose Setup” screen and then by pressing “Background”.
Whenever the background spectrum is being used by the device the user is given
the option to update the spectrum.
1) The measure time can be adjusted if
desired.
Press “Start” at the bottom of the screen to
begin collecting2) While the background is being measured thegreen bar at the bottom shows the progress.
To conclude the measurement early press‘stop’.
‘Abort’ will abandon the measurement.

123) After the background has been acquiredpress ‘OK’ to accept the background.
After pressing “Accept” the “Dose” screen will be
displayed.

13Section 6: Dose Setup and CPS Alarm
1) Press “Setup”.

2) Enter the required “Integration Time” thenpress “OK”. The default value is 60 seconds.

3) Enter the required “Update Time” and press“OK”. The default value is 10 seconds.
Press “Back”.

144) Enter the required Counts Per Second (CPS)
alarm. The default value is 30,000.

5) When the count rate exceeds the alarm value
the background will turn red.
A log file of alarms is also written to the device.
Please see the section on exporting data
manually for how to access the log files.
6) The units used by the RayMon10 can be
configurated between SI (dose in µSv/h) or US
Standard (dose in mrem/h) using the drop down
box.

15

Section 7: Search Mode
1) From the front ‘Dose’ screen press “Search”.

2) Search mode works by comparing themeasured total counts from the detector in a fast
response channel (red line) to a backgroundlevel (blue line).

If the measured counts exceed the backgroundlevel by a significant amount, the user is alerted
to the presence of a radiation source by thecount rate box becoming red and the graphbeing given a red shading.

163) Pressing ‘setup’ allows the search mode to
be configured.
Fast Integration Time
This determines the integration time of the fastchannel. By default this is 1 second.
Confidence Limit
This is the level above the background that
results in the alarm being triggered. By default
this is 99.999% which equates to less than 1
false alarm every 10 hours meeting the ANSI
N42.48 standard.
Audible Alarm
Check this box to have an alarm sounded whena radiation source is detected.
4) If the background is set to ‘Auto-track’ in the
setup, a slow rolling average of the counts ismaintained.
The background integration time should be longcompared to the fast integration time.
By default this is set at 60 seconds. It is notrecommended to use values below 20 seconds

5) Note that when using an auto-tracked
background the background counts are affectedby the counts in the fast channel.
It may take time for the background to return toa realistic level after finding a source.
Longer background integration times are lesssusceptible to a short increase in count rate,
although once they have been affected theytake longer to return.

176) The alternative to an auto-tracked
background is to record the background thenuse it as a constant reference level. Remove thetick from the auto-track check box.
The fixed background level in counts per second(cps) is displayed, along with how long ago thebackground was recorded. Press ‘update’ torecord a new background level.

7) The existing background spectrum will be
displayed.
The “measure time” can be adjusted to set the
duration of the acquisition.
By default this is set to 60s.
Press ‘Start’ on the green bar to start a newacquisition.

8) While the background is being measured thegreen bar at the bottom shows the progress.
To conclude the measurement early press‘stop’.
‘Abort’ will abandon the measurement.

189) After the background has been acquiredpress ‘OK’ to accept the background.
10) Press ‘Accept’ to return to the dynamic
search screen.

11) Press ‘back’ to return back to the Search.

Section 8: Measurement Setup
1) Press “Measurement”.

2) Press “Setup”.

3) the Measurement Setup screen will be
displayed with the settings arranged on threetabs.
Note that the RadBar and Identify tabs are only
available if the associated checkboxes areticked on the measure tab.

204) Enter the required measurement time inseconds then press “OK”. If a measure time of
0s is entered the measurement will continue
indefinitely until the user presses either ‘Finish’or ‘Abort’.
The measurement time refers to real time unlesslive time is enabled by selecting the check box.
Real time is the total time of the measurement.
Live time is the length of time that the pulse
processing hardware has actually been active
and able to detect pulses during the dataacquisition. Therefore, live time is the real time
reduced by the total time that the hardware has
been inactive as a result of pulse processing
activities.
5) The “RadBar On” check box determines
whether a RadBar is available during and after ameasurement.
A RadBar shows the dose contribution from theincident gamma rays as coloured bins on anenergy scale. It allows the dose contribution
from different radionuclides to be identified.

6) The scaling of the RadBar can be configured
by selecting one of the options in the RadBar tab:•••

“To Max” adjusts the scale so the highest
value in any bin is at the top of the scale“Fixed ” applies a constant scale,configurable in dose units of µSv/hour or
mrem/hour“Total” rescales the whole RadBar to thetotal dose rate

The colours used for “To Max” and “Fixed”
scaling can be configured by selecting the colour
box and choosing a colour and then entering thelevel where this colour should be used.
Intermediate data points are represented by aninterpolated colour.
21.

7) The critical limit parameter is used to adjust
the sensitivity with which peaks are detected
when analysing the spectrum. Click on thecritical limit box to change the value. The default
value for this is 99.9%.

8) The Confidence Limit parameter is used
when calculating the upper and lower bounds
for net counts in a peak region. This confidencewith which these values are calculated can be
adjusted by clicking in the Confidence Limit box
and altering the value. The default value is 95%.

9) The ROI width factor determines the width ofthe peak region used for analysis calculations.
Reducing this percentage makes the peakregion narrower and will affect the values shownin the results table, e.g. net counts. To change
this value click the “ROI width factor” box andselect a different value. The default value forthis parameter is 95.45%.

2210) The Lower Level Discriminator (LLD) value
cannot be altered. It is the threshold below
which the detector’s electronics cannot registera signal and is determined by the firmware on
the detector.

11) If “Auto Save” is ticked each measurement
will automatically be saved and identified by thedate and time of the measurement.
If “Auto Repeat” is enabled the measurement
will be saved and the RayMon will then
immediately
begin
acquiringanewmeasurement. This is performed a set numberof times. If 0 is entered in the repeat number
box the repetitions continue indefinitely until theuser presses either “Finish” or “Abort”.
Press the “Back” button to return to the“Measurement” Screen.

12) When ‘Identify On’ is checked automatedradionuclide ID is available after a measurement
has been completed.

23Section 9: Making a Measurement

5) The + and – buttons can be used to zoom
in/out on the peak of interest.
Zooming in can also be achieved by double
tapping the graph.
Zooming out by holding the stylus stationary on
the graph for 1s or more and then releasing.
The peak can also be moved by using a fast
swipe with the stylus on the graph.

6) The green cursor can be used to measure
the counts in a specific channel. Use the stylus
to move the cursor position.
A single tap with the stylus will position the
cursor. To drag the cursor, not the graph, holdthe stylus stationary on the graph for 1s or morethen move the cursor.

257) If RadBar has been enabled in themeasurement settings, pressing the ‘RadBar’
button will display the RadBar of themeasurement and the total dose rate measured.
