    The results of exposure measurements using film badges and thermoluminescent dosimetry (TLD) were compared at an operating nuclear power reactor. The film badge overresponded to the high-energy Nitrogen-16 gamma rays produced under power, while the TLD did not. Discussions of charged-particle equilibrium and energy dependence are included. The cause of the overresponse was determined to be the excess pair production electrons created because of the high atomic number in the lead energy-compensating shield surrounding the film and in the film itself.
