Abstract
  • CR-39 foils were irradiated as part of nuclear accident dosimetry experiments using the Godiva reactor at the Nevada National Security Site and the Caliban and Prospero reactors at the Valduc Centre for Nuclear Studies in France. The irradiated foils were chemically etched using the standard Lawrence Livermore National Laboratory process for personnel neutron dosimeters. Following chemical processing, the optical density of the CR-39 foils was measured using a transmission densitometer and found to be a function of the fast neutron dose as measured by the neutron activation components of the nuclear accident dosimeters. The relationship between fast neutron absorbed dose and optical density exponentially approaches a maximum at an absorbed dose of about 1 Gy. For the chemical etching process used in this study, neutron doses above 1 Gy did not further increase the optical density of the CR-39 foils.
