Title: Mixed field radiation dosimeter

Abstract

A dosimeter for use in mixed radiation fields is disclosed. The dosimeter consisting of a single element may be used in a photon-neutron field if the energies of the photons and neutrons are known. In a mixed photon-neutron-beta radiation field of unknown energies, a detector having four elements is sufficient to provide an estimate of the exposure. The dosimeter makes use of the high temperature readout from a 6Li doped LiF thermoluminescent detector to provide an estimate of both the neutron and photon exposures.
