U.S. Nuclear Regulatory Commission

Question 223: Are radiographers exempt from posting at a

temporary field site, under 10 CFR 20.1903 (a), since they

perform radiography in each area less than 8 hours, attend

the material to prevent exposure of individuals in excess

of the limits (i.e., have clear sight over the designated

area and are in constant attendance), and control the area

(i.e., tell individuals to leave if they come too close to

the source)?

Answer: The revised Part 20 requirements do not change

this exemption. Radiographers continue to be exempt under

20.1903 (a); however, industrial radiographers are required

under 10 CFR 34.42 to conspicuously post areas where

radiography is being performed. (Reference: 10 CFR

20.1903, 34.42)
