Personnel Neutron Dosimeter for Nuclear Accident

Abstract

Two types of personnel dosimeter are presented: an emulsion containing IOB and T h'b 1 d dl bd' al. a osiagass-cove~e mo e em o ymg natur uranmm foiL If a Cd sheet is used to rerluce thermal neutrons leavmg the human body, measurements of the dose equivalent will be poss,:J!e to cover a neutron energy ra~e betw~en thermal ~d 10 MeV. Experimental results show that the minimum detectable d?Be eqmvalent. with the dosimeters are 0.15 rem and 10 rem for the emulsion type and the etched pit type, respectively.
