Each film badge, OSLD, and TLD must be assigned to and worn by only one individual. Film badges must be replaced at least monthly and OSLDs and TLDs must be replaced at least quarterly. After replacement, each film badge, OSLD, and TLD must be processed promptly.

Acceptable dosimeters must read within 30 percent of the true radiation dose.
