(All doses should be stated in rems)
11A. EDEX – Enter the EDEX for the entire monitoring period

methods).

monitored in the format (MM/DD/YYYY).
6. Enter the monitoring period for which this report is filed.
The format should be (MM/DD/YYYY) - (MM/DD/YYYY).

16. Enter the committed dose equivalent (CDE) recorded for the
maximally exposed organ.

7. Enter the name of the licensee or facility not licensed by
NRC that provided monitoring.

17. Enter the total effective dose equivalent (TEDE). The TEDE
is the sum of items 11a and 15.

8. Enter the NRC license number or numbers.

18. Enter the total organ dose equivalent (TODE) for the
maximally exposed organ. The TODE is the sum of items
11b and 16.

9. Place an “X” in Record, Estimate, or No Record. Choose
“Record” if the dose data listed represent a final
determination of the dose received to the best of the
licensee’s knowledge. Choose “Estimate” only if the listed
dose data are preliminary and will be superseded by a
final determination resulting in a subsequent report. An
example of such an instance would be dose data based
on self-reading dosimeter results and the licensee intends
to assign the record dose on the basis of TLD results that
are not yet available. If the individual or an organization
has indicated that the individual was monitored, but the
monitoring records could not be obtained, enter “No
Record” for this monitoring period. The individual would
not be available for a PSE. For monitoring periods during
the current year where records are not available, reduce
the individual’s allowable dose by 1.25 rems for each
quarter for which records were unavailable as required by
10 CFR 20.2104(e)(1).
10. Place an “X” in either Routine or PSE. Choose “Routine”
if the data represent the results of monitoring for routine
exposures. Choose “PSE” if the listed dose data
represents the results of monitoring of planned special
exposures received during the monitoring period.

19. Signature of the monitored individual. The signature of the
monitored individual on this form indicates that the
information contained on the form is complete and correct to
the best of his or her knowledge.
20. Enter the date this form was signed by the monitored
individual.
21. [OPTIONAL] Enter the name of the licensee or facility not
licensed by NRC, providing monitoring for exposure to
radiation (such as a DOE facility) or the employer if the
individual is not employed by the licensee and the employer
chooses to maintain exposure records for its employees.
22. [OPTIONAL] Signature of the person designated to represent
the licensee or employer entered in item 21. The licensee or
employer who chooses to countersign the form should have
on file documentation of all the information on the NRC
Form 4 being signed.
23. [OPTIONAL] Enter the date this form was signed by the
designated representative.

PRIVACY ACT STATEMENT
NRC FORM 4
CUMULATIVE OCCUPATIONAL DOSE HISTORY
Pursuant to 5 U.S.C. 552a(e)(3), enacted into law by Section 3 of the Privacy Act of 1974
(Public Law 93-579), the following statement is furnished to individuals who supply
information to the U.S. Nuclear Regulatory Commission (NRC) on NRC Form 4. This
information is maintained in a system of records designated as NRC-27 and described at 84
Federal Register 71558 (December 27, 2019), or the most recent Federal Register
publication of the NRC's Systems of Records Notices that is located in NRC's Agencywide
Documents Access and Management System (ADAMS).
1. AUTHORITY: 5 U.S.C. 7902; 29 U.S.C. 668; 42 U.S.C. 2051, 2073, 2093, 2095, 2111,
2133, 2134, and 2201(o); 10 CFR Parts 20 and 34; Executive Order (E.O.) 9397, as
amended by E.O. 13478; E.O. 12196, as amended; E.O. 13708.
2. PRINCIPAL PURPOSE(S): The information is used by the NRC in its evaluation of the
risk of exposures to radiation and radioactive material associated with licensed activities
and in exercising its statutory responsibility to monitor and regulate the safety and health
practices of its licensees. The data permits a meaningful comparison of both current and
long-term exposure experience among types of licensees and among licensees within each
type. Data on your exposure to radiation is available to you upon your request.
3. ROUTINE USE(S): In addition to the disclosures permitted under subsection (b) of the
Privacy Act, information may be used to provide data to other Federal and State agencies
involved in monitoring and/or evaluating radiation exposure received by individuals
monitored for radiation exposure while employed by or visiting or temporarily assigned to
certain NRC licensed facilities; and to return data provided by licensee upon request.
Information may be disclosed in accordance with any of the Routine Uses listed in the
Prefatory Statement of General Routine Uses, including to an appropriate Federal, State,
local or Foreign agency in the event the information indicates a violation or potential
violation of law; in the course of an administrative or judicial proceeding; to an appropriate
Federal, State, local and foreign agency to the extent relevant and necessary for an NRC
decision about you or to the extent relevant and necessary for that agency's decision about
you; in the course of discovery under a protective order issued by a court of competent
jurisdiction, and in presenting evidence; to a Congressional office to respond to their inquiry
made at your request; to NRC-paid experts, consultants, and others under contract with the
NRC, on a need-to-know basis; or to appropriate persons and entities for purposes of
response and remedial efforts in the event of a suspected or confirmed breach of data from
this system of records.
4. WHETHER DISCLOSURE IS MANDATORY OR VOLUNTARY AND EFFECT ON
INDIVIDUAL OF NOT PROVIDING INFORMATION: It is voluntary that you furnish the
requested information, including the Social Security number (SSN) in block #2. The SSN is
used to assure that NRC has an accurate and unique identifier not subject to the
coincidence of similar names or birth dates among the large number of persons on who
data is maintained and to assure that there are no missed doses or monitoring periods and
an individual gets a complete dose history when requested. The licensee must complete
NRC Form 5 on each individual for whom personnel monitoring is required under 10 CFR
20.1502. In addition, licensees must submit this information to NRC in accordance with the
requirement under 10 CFR 20.2206. Failure to do so may subject the licensee to
enforcement action in accordance with 10 CFR 20.2401.
5. SYSTEM MANAGER AND ADDRESS: REIRS Project Manager, Radiation Protection
Branch, Division of Systems Analysis, Office of Nuclear Regulatory Research, U.S. Nuclear
Regulatory Commission, Washington, DC 20555-0001.
