Abstract

The evaluation method of neutron dose equivalent was studied on the basis of the albedo type neutron dosimetory to design the personnel dosimeter. The dosimeter was composed of three ⁶Li₂¹⁰B₄O₇(Cu) TL elements and one ⁷Li₂¹¹B₄O₇(Cu) element.
The equations for assessing thermal, epithermal and fast neutron dose equivalents were derived by ²⁵²Cf, ²⁴¹Am-Be and PuO₂ neutron sources.
The minimum detectable amount of ⁶Li₂¹⁰B₄O₇(Cu) element to thermal neutron was 0.02 mrem. The neutron dose equivalent and the gamma one were evaluated separately within about 20% error in the mixed radiation field.
