Thermal and Fast Neutron Effects on Dosimeter Films
Abstract
To accurately measure the initial gamma radiation from atomic detonations, the effect of neutrons on gamma detectors was evaluated. Eight film types, encased in NBS holders and covering a range of 0.3 to 50,000 r, were exposed to thermal-and-fast-neutron radiation. The lithium extrapolation method was used in the evaluation. Two points seem evident concerning the fast-neutron sensitivity of film: (1) the sensitivity of the film increases with increasing neutron energy from 1 to 14 Mev and (2) the ratio of the sensitivity of the film is roughly equal to the reciprocal of the ratio of their grain sizes.
