The U.S. Nuclear Regulatory Commission (NRC) issues regulatory guides to describe and make available to the public methods that the NRC staff considers acceptable

for use in implementing specific parts of the agency’s regulations, techniques that the staff uses in evaluating specific problems or postulated accidents, and data that the

staff need in reviewing applications for permits and licenses. Regulatory guides are not substitutes for regulations, and compliance with them is not required. Methods

and solutions that differ from those set forth in regulatory guides will be deemed acceptable if they provide a basis for the findings required for the issuance or continuance

of a permit or license by the Commission.

This guide was issued after consideration of comments received from the public. The NRC staff encourages and welcomes comments and suggestions in connection

with improvements to published regulatory guides, as well as items for inclusion in regulatory guides that are currently being developed. The NRC staff will revise existing

guides, as appropriate, to accommodate comments and to reflect new information or experience. Written comments may be submitted to the Rules and Directives Branch,

Office of Administration, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001.

Regulatory guides are issued in 10 broad divisions: 1, Power Reactors; 2, Research and Test Reactors; 3, Fuels and Materials Facilities; 4, Environmental and Siting;

5, Materials and Plant Protection; 6, Products; 7, Transportation; 8, Occupational Health; 9, Antitrust and Financial Review; and 10, General.

REGULATORY GUIDE 8.7

(Draft was issued as DG-8029, dated May 2005)

INSTRUCTIONS FOR RECORDING AND REPORTING

OCCUPATIONAL RADIATION DOSE DATA

A. INTRODUCTION

In Title 10, Part 20, of the Code of Federal Regulations (10 CFR Part 20), “Standards for Protection

Against Radiation,” Section 20.1502 establishes “Conditions Requiring Individual Monitoring of External and

Internal Occupational Dose.” Specifically, 10 CFR 20.1502 requires licensees to provide radiation monitoring

for all occupationally exposed individuals who might receive a dose in excess of the specified percentage of the limits

defined in 10 CFR 20.1201, 1207, or 1208. To augment that provision, 10 CFR 20.2106, “Records of Individual

Monitoring Results,” requires licensees to maintain records of the radiation exposures of all individuals for whom

personnel monitoring is required pursuant to 10 CFR 20.1502. Also, according to 10 CFR 20.2104, “Determination

of Prior Occupational Dose,” licensees shall determine the dose in the current monitoring year for all persons

who must be monitored, and attempt to obtain the records of cumulative occupational radiation dose. In addition,

10 CFR 20.2104(b) requires that, prior to permitting an individual to participate in a planned special exposure,

licensees shall determine the internal and external doses from all previous planned special exposures, and record

all previous doses in excess of the limits received during the lifetime of the individual. Licensees are required

to maintain prior dose records on NRC Form 4 or its equivalent (Appendix A to this guide). Further, 10 CFR 20.2206,

“Reports of Individual Monitoring,” requires certain licensees to submit to the U.S. Nuclear Regulatory Commission

(NRC) an annual report of the results of individual monitoring. Licensees are required to record these annual reports

on NRC Form 5 or its equivalent (Appendix B to this guide).
RG 8.7, Rev. 2, Page 2

This guide describes an acceptable program for the preparation, retention, and reporting of records

of occupational radiation doses. It includes copies of NRC Forms 4 and 5, as well as detailed instructions

for completing those forms.

Any information collections mentioned in this regulatory guide are established as requirements

in 10 CFR Part 20, which provides the regulatory basis for this guide. The Office of Management

and Budget (OMB) has approved those information collection requirements under OMB control number

3150-0014. The OMB has also approved the existing requirements for NRC Forms 4 and 5 under

approval numbers 3150-0005 and 3150-0006. However, the amended information collection requirements

reflected in this guide will not become effective until they receive OMB approval. Notice of OMB

approval will be published in the Federal Register. The NRC may neither conduct nor sponsor,

and a person is not required to respond to, an information collection request or requirement unless

the requesting document displays a currently valid OMB control number.

B. DISCUSSION

This guide is structured to reflect the process a licensee would follow to decide whether

monitoring for occupational exposure to radiation is required under the revised 10 CFR Part 20. 

Toward that end, this guide describes acceptable methods for determining prior doses, recording

monitoring results, and reporting those results, when required, to comply with 10 CFR Part 20. 

This guide also includes copies of NRC Forms 4 and 5, as well as detailed instructions for completing

those forms. In addition, Appendix C to this guide discusses the format for electronic submittal of

dose data to the NRC.

The term “total organ dose equivalent” (TODE) has been added to denote the sum of the deep dose

equivalent (DDE) and the committed dose equivalent (CDE) to the organ receiving the highest dose,

as described in 10 CFR 20.2106(a)(6).
RG 8.7, Rev. 2, Page 3

C. REGULATORY POSITION

1. Determining the Need To Monitor

According to 10 CFR 20.1502, monitoring is required if an adult is likely to receive

in a calendar year a dose greater than the specified percentage of the limits defined in 10 CFR 20.1201,

1207, or 1208, or is entering a high or very high radiation area. The licensee should evaluate the dose

that such an individual is likely to receive before allowing the individual to receive the dose. The licensee

need not perform a dose evaluation for every individual; evaluations can be performed for employees

with similar job functions or work areas. Regulatory Guide 8.34, “Monitoring Criteria and Methods

To Calculate Occupational Radiation Doses” (July 1992), provides further guidance for use in determining

the need to monitor an individual’s occupational radiation dose.

1.1 If Monitoring Is Not Required

If the prospective evaluation shows that an individual is not likely to receive in a calendar year

a dose that exceeds the specified percentage of the limits defined in 10 CFR 20.1201, 1207, or 1208,

10 CFR Part 20 does not require recordkeeping or reporting regarding the individual’s dose. For individuals

who received a dose at other facilities in the current year, the previous dose need not be considered

in this prospective evaluation. Only the dose that could be received at the facility performing the evaluation

need be considered when determining the need for monitoring and, therefore, the recordkeeping

and reporting requirements. If the licensee determines that monitoring is not required and a subsequent

evaluation shows that the individual exceeded (or will exceed) the monitoring limit threshold,

the licensee should estimate, record, and report the dose received when monitoring was not provided. 

These estimates can be based on any combination of work location radiation monitoring or survey results,

monitoring results of individuals in similar work situations, or other estimates to produce a “best estimate”

of the actual dose received.

If monitoring is not required to demonstrate compliance with all limits, but is required relative to

one or more specific limits, the licensee should enter “NR” for “Not Required” in the blocks on NRC

Forms 4 and 5 to indicate the areas for which monitoring was not required (e.g., extremity or skin doses). 

Where monitoring was provided but the dose was not measurable, the licensee should enter “ND” for

“Not Detectable.”

1.2 If Monitoring Is Required

If the prospective evaluation shows that an individual is likely to receive in a calendar year

a dose that exceeds the specified percentage of the limits defined in 10 CFR 20.1201, 1207, or 1208, 10

CFR 20.1502 requires monitoring. In addition, 10 CFR 20.2106(a) and 20.2206(b), respectively, require

recording and reporting of the monitoring results, regardless of the actual dose received (even if the

actual dose received is less than the dose limits for which monitoring is required).
RG 8.7, Rev. 2, Page 4

1.3 Documentation of Prior Doses

For those individuals for whom monitoring is required (i.e., individuals who are likely to receive

in a calendar year, an occupational dose requiring monitoring pursuant to 10 CFR 20.1502), 10 CFR 20.2104

requires a determination of the individual’s current year dose at other facilities. For individuals entering

a high or very high radiation area, determination of current year prior occupational dose is not required

unless the individual is likely to receive in a year, an occupational dose greater than the specified percentage

of the limits defined in 10 CFR 20.1201, 1207, or 1208. To document that determination, the licensee

is required to obtain an NRC Form 4 signed by the individual to be monitored, or a written statement

that includes the names of all facilities that monitored the individual for occupational exposure to radiation

during the current year and an estimate of the dose received. Although not required by the regulations,

it is considered good health physics practice to verify the information provided by the individual. 

Verification may be documented in any of the following ways:

• an NRC Form 5 for each listed monitoring period

• electronic, telephone, or facsimile transfer of dose data provided by licensees listed

on the written statement

• an NRC Form 4 countersigned by a licensee or current employer

In addition, 10 CFR 20.2104(a)(2) requires that licensees must attempt to obtain records of

the individual’s lifetime cumulative occupational radiation dose. To demonstrate compliance with this

requirement, the individual to be monitored may provide a written estimate of the cumulative lifetime

dose or an up-to-date NRC Form 4 signed by the individual. The licensee need not verify this

information, so long as the individual does not participate in a planned special exposure.

NRC Forms 4 and 5, termination letters, and/or reports that document the results of monitoring

performed before implementation of the 1991 revision of 10 CFR Part 20 may be used without recalculating

dose according to the requirements of the 1991 revision of 10 CFR Part 20. For the purpose of assessing

prior dose, whole body dose, in rem, as reported on the old NRC Forms 4 and 5 (from 1981 or earlier)

can be considered equivalent to total effective dose equivalent (TEDE).

1.4 Records of Prior Dose for Persons Participating in Planned Special Exposures

If the monitored individual has any periods of exposure (throughout his or her life) that have not

been monitored and documented, the individual is not permitted to participate in a planned special

exposure. Acceptable documentation of prior exposure is similar to that required to document

current-year exposure. The licensee may ask the NRC to provide a report of the monitored individual’s

exposure history, by submitting a request via the NRC’s Radiation Exposure Information and Reporting

System (REIRS) for Radiation Workers (a secure web site) at http://www.reirs.com. Alternatively,

the licensee may send a request signed by the monitored individual to the following point-of-contact:

REIRS Project Manager

Office of Nuclear Regulatory Research

U.S. Nuclear Regulatory Commission

Washington, DC 20555

Each request should contain the social security number (or other unique identifier) of the

monitored individual authorizing release of the information and the name and address of the person or

licensee to whom the report should be sent. The NRC’s REIRS database contains copies of all licensee

exposure records submitted to the NRC. However, the database only contains reports submitted by the

seven classes of licensees that 10 CFR Part 20 requires to report occupational exposures. Any missing

monitoring periods should be obtained directly from licensees.
RG 8.7, Rev. 2, Page 5

1.5 Use of ID Types Other than Social Security Number

Doses to individuals who do not have a social security number, such as citizens of foreign countries,

and individuals who are either unwilling or unable to provide (cannot locate or do not want to disclose)

a social security number, should be reported using another unique identifier. It is important to record

the type of identification in the data block labeled “ID Type,” which follows the “Identification Number”

data block on NRC Forms 4 and 5. The instructions on the back of these forms define all valid ID types. 

Licensees should insert the appropriate code (listed below) in the blank labeled “ID Type”.

ID TYPE CODE

U.S. Social Security Number SSN

Passport Number PPN

Canadian Social Insurance Number CSI

Work Permit Number WPN

INDEX Identification Number IND

PADS Identification Number PAD

Other OTH

The use of licensee-generated identification numbers should be avoided whenever possible.

2. Records of Monitoring Results for Individuals for Whom Monitoring Is Required

The preparation of NRC Form 5 with the information clearly and legibly shown, or the collection

of all information requested by NRC Form 5 using paper or electronic media (see Appendix C), is required

by 10 CFR 20.2106. The licensee shall maintain such records for each individual for whom occupational

monitoring is required by 10 CFR 20.1502. In addition, certain classes of licensees are required to report

the results of this monitoring to the NRC, pursuant to 10 CFR 20.2206, either by submitting copies

of NRC Form 5 or by transmitting the required information to the NRC through electronic media. 

This report, covering the preceding year, must be filed on or before April 30 of each year. NRC Form 5

provides instructions and additional information pertinent to each item.

2.1 Multiple Badges

Regulatory Guide 8.34, “Monitoring Criteria and Methods To Calculate Occupational Radiation

Doses” (July 1992), provides further guidance on interpreting the results of multiple dosimetric devices

placed at different locations on the body to track doses to various parts of the whole body. In addition,

NRC Regulatory Issue Summary 2002-06, “Evaluating Occupational Doses Exposed to NRC-Licensed

Material and Medical X-rays” (April 16, 2002), provides additional guidance.
RG 8.7, Rev. 2, Page 6

2.2 Dose Calculations for CDE and TODE to the Maximally Exposed Organ

As required by 10 CFR 20.2106(a)(6), licensees shall record, when applicable, the total organ

dose equivalent (TODE), which is the sum of the deep dose equivalent (DDE) and the committed dose

equivalent (CDE) to the organ receiving the highest dose (the maximally exposed organ). For cases

where the licensee is using effective dose equivalent (EDE) in lieu of DDE (please refer to NRC

Regulatory Issue Summary 2003-04, “Use of the Effective Dose Equivalent in Place of the Deep Dose

Equivalent in Dose Assessments”), record the EDE in item number 11 of NRC Form 5 and note

in the comment block that EDE is being used in lieu of DDE. Organ doses need not be calculated

if the committed effective dose equivalent (CEDE) does not exceed 1 rem, and there are no overexposures

in any dose category within the monitoring year, including doses previously reported by other licensees. 

In this case, the licensee may record “NC” for “Not Calculated” in items 16 and 18 on NRC Forms 4 and 5. If

during the course of the year, the CEDE to date for the year exceeds 1 rem or the individual receives

an overexposure in another dose category, the licensee is required to calculate, record, and report the CDE

and TODE to the maximally exposed organ. When the CDE and TODE to the maximally exposed organ

are required to be calculated, the licensee should refer to Regulatory Guide 8.34, “Monitoring Criteria

and Methods To Calculate Occupational Radiation Doses” (July 1992).

2.3 Dose to the Embryo/Fetus

A declared pregnant worker is a worker who has voluntarily informed her employer (in writing)

of her pregnancy and the estimated month and year of conception. In such instances, the licensee shall

record the dose to the embryo/fetus for the entire gestation period [10 CFR 20.2106(e)], but need not

include that information on NRC Forms 4 and 5. Multiple records are not required in the case of

multiple births (twins, triplets, etc.). Licensees are required to record any dose measured to demonstrate

compliance with 10 CFR 20.1208.

Licensees should be sensitive to the issue of personal privacy with regard to the dose to the

embryo/fetus. If requested by the monitored woman, a letter report may be provided to subsequent

licensees to document prior embryo/fetus dose. Regulatory Guide 8.36, “Radiation Dose to the

Embryo/Fetus” (July 1992), provides further guidance on assessing the dose to the embryo/fetus.

2.4 Transmittal of Reports to the NRC

As required by 10 CFR 20.2206(c), certain licensees are required to submit reports of monitoring

for the previous year to the NRC on or before April 30 of each year. According to 10 CFR 20.2206(b),

“...The licensee shall use Form NRC 5 or electronic media containing all the information required by

Form NRC 5.” Licensees shall submit their reports to the REIRS Project Manager by an appropriate method

listed in 10 CFR 20.1007 or via the REIRS Web site at http://www.reirs.com. Reports submitted by mail

should be addressed as follows:

REIRS Project Manager

Office of Nuclear Regulatory Research

U.S. Nuclear Regulatory Commission

Washington, DC 20555

2.5 Electronic Reporting of Dose Data

Licensees (especially those with a large number of monitored individuals) are encouraged

to record and report these data electronically. Appendix C to this guide provides guidance for reporting

radiation dose data to the NRC in an electronic, machine-readable format.
RG 8.7, Rev. 2, Page 7

D. IMPLEMENTATION

The purpose of this section is to provide information to applicants and licensees regarding

the NRC staff’s plans for using this guide. No backfitting is intended or approved in connection with

the issuance of this guide.

Except in those cases in which an applicant or licensee proposes or has previously established

an acceptable alternative method for complying with specified portions of the NRC’s regulations, the

methods to be described in the active guide will reflect public comments and will be used in evaluating

(1) submittals in connection with applications for new licenses, license renewals, and license

amendments, and (2) compliance with 10 CFR 20.1001-20.2401.

SMALL BUSINESS 

REGULATORY ENFORCEMENT FAIRNESS ACT

The NRC staff has determined that this final action is subject to the Small Business Regulatory

Enforcement Fairness Act of 1996 because it is the whole or part of a final agency action that has general

applicability and future effect designed to implement, interpret, or prescribe law or policy. However,

the final action does not constitute a “major rule” as defined in 5 U.S.C. 804(2).

REGULATORY ANALYSIS

The NRC staff did not prepare a separate regulatory analysis for this regulatory guide. 

The regulatory analysis prepared for 10 CFR Part 20, “Standards for Protection Against Radiation”

(56 FR 23360), also provides the regulatory basis for this guide and examines the costs and benefits

of the rule as implemented by the guide. A copy of the “Regulatory Analysis for the Revision of

10 CFR Part 20” (PNL-6712, dated November 1988), is available (as an enclosure to 10 CFR Part 20)

for inspection and copying for a fee at the NRC’s Public Document Room, located at 11555 Rockville Pike,

Rockville, Maryland.

APPENDIX C

FORMAT FOR ELECTRONIC SUBMITTAL OF DOSE DATA

Introduction

This appendix outlines a means by which licensees may satisfy the requirements of 10 CFR 20.2206,

“Reports of Individual Monitoring.” Where practicable, the NRC prefers to have licensees submit an

electronic file via the Radiation Exposure Information and Reporting System (REIRS) for Radiation

Workers (a secure Web site) at http://www.reirs.com. Regardless of submittal method, licensees who

have their exposure records in an electronic format are encouraged to submit electronic files. This is

especially important for those licensees who have a large number of monitored individuals, because data

entry is inefficient and can introduce an additional source of error.

Media Requirements

For electronic data mailed to the REIRS Project Manager (PM), the following data storage media are

compatible with REIRS. Other data submission formats may also be acceptable. The NRC will provide

additional guidance to licensees upon request to the REIRS Project Manager.

• PC Diskettes: 31⁄2-inch

Standard IBM-PC format

ASCII character format

• Compact Disk (CD-ROM): Standard IBM-PC format

ASCII character format

Transmittal Letters

For electronic files that are not submitted through the REIRS Web site, the licensee should also

submit a transmittal letter containing information that will minimize processing time and help resolve

possible discrepancies. Each letter should contain the following information (as a minimum):

• File name Descriptive name of the file(s) contained on the disk

• Date created Date each file was created

• Operating system Operating system and version used to format the disk

• Contact Name and telephone number of the cognizant point-of-contact

• Other instructions Comments or explanation regarding the submission, the actual date,

the data format, or other important information

• Signature and date Dated signature of the licensee’s authorized representative responsible

for the data
Appendix C to RG 8.7, Rev. 2, Page C-2

Expected Data

Each licensee is expected to submit one routine NRC Form 5 for each monitored individual at the given

facility for each monitoring year. Licensees should also submit a separate NRC Form 5 for each individual

for whom planned special exposures were authorized. Because there should be few repetitions,

the employee information is included on the Form 5. The primary license number is also included

on each Form 5 to ensure that the records are assigned to the proper facility.

File Structure

The file structure consists of a header record, which provides information about the source of the data

file, followed by Form 5 dose records and supporting Form 5 intake records. Where applicable, the file

may also include one or more Form 5 comment records to explain special exposure calculations or

overexposures. Each record contains only ASCII or EBCDIC printable characters and is terminated with

a carriage return (CR) and a line feed (LF). All empty space in a field is padded with spaces. Text

strings are left justified in a field, and numbers are right justified in a field.

Header Record

The header record occurs only once at the top of each file to identify the source of the data.
