Abstract

This paper describes the principle and method for determining the relative neutron sensitivity (

) of the photon dosimeters. With a modified lead attenuation method

the

values of a 2cm

C-CO

(FWT

IC-17G) and a 3cm

Al-Ar (FWT

IC-17A1) chambers were determined as 0.271±0.021 and 0.132±0.006 respectively.

of a Geiger-muller counter (FWT

GM-2 (446)) was determined as 0.0173±0.002. Comparing these results with other experimental data one can find that the relative neutron sensitivity (

) of the photon dosimeters was

not

very sensitive to the

of photon component. The uncertainty of

measured in the lead filtration method was estimated. The neutron and gamma absorbed-doses for ICRV muscle tissues in same mixed field have been measured by technique of paired detectors.
