Radiological Safety Training for Uranium Facilities

Module 103 External Dose Control

Personnel dosimeters produce the data which becomes the formal or "legal" record

of personnel exposure, thermoluminescent dosimeters, used in most DOE uranium

facilities, provides the most accurate and precise means of measuring doses

received by workers.

External Dose Reduction and Control Techniques

1. External Dose Control Program

The primary purpose of an external dose control program is to control dose to

the individual radiation worker to below regulatory limits and administrative

levels and ensuring that doses are As Low As Reasonably Achievable

(ALARA). In all cases at DOE facilities, dose received by an individual shall

not exceed the limits specified in Title 10 of the Code of Federal Regulations,

Part 835 (10 CFR 835).

The elements of an external dose control program include:

detecting and characterizing the beta, gamma, X-ray, and neutron radiation

fields;

measuring and/or quantifying these radiation fields;

measuring personnel exposure; and

determining external exposure control practices.
