Response of a gamma -Ray 'Telescope' Dosimeter to the (N + gamma ) Radiation from a sup 239 Pu-Be Source

摘要

The design, construction, and investigation of a gamma-ray telescope that can tell the direction of incident photons is reported. The dosimeter is based on LiF thermoluminescence. The gamma-ray telescope dosimeter was tested with a sup 239 Pu-Be source and found to perform satisfactorily. For a high-energy neutron field the gamma-ray telescope dosimeter contributes very little to the total dose equivalent. (ERA citation 11:001250)
