Sec. 36.55  Personnel monitoring.

    (a) Irradiator operators shall wear either a film badge or a 
thermoluminescent dosimeter (TLD) while operating a panoramic irradiator 
or while in the area around the pool of an underwater irradiator. The 
film badge or TLD processor must be accredited by the National Voluntary 
Laboratory Accreditation Program for high energy photons in the normal 
and accident dose ranges (see 10 CFR 20.1501(c)). Each film badge or TLD 
must be assigned to and worn by only one individual. Film badges must be 
processed at least monthly, and TLDs must be processed at least 
quarterly.
    (b) Other individuals who enter the radiation room of a panoramic 
irradiator shall wear a dosimeter, which may be a pocket dosimeter. For 
groups of visitors, only two people who enter the radiation room are 
required to wear dosimeters. If pocket dosimeters are used to meet the 
requirements of this paragraph, a check of their response to radiation 
must be done at least annually. Acceptable dosimeters must read within 
plus or minus 30 percent of the true radiation dose.

    Effective Date Note: At 65 FR 63752, Oct. 24, 2000, Sec. 36.55 was

irradiator or while in the area around the pool of an underwater 
irradiator. The personnel dosimeter processor must be accredited for 
high energy photons in the normal and accident dose ranges (see 10 CFR
