Accidental Neutron Dosimetry with Human Hair

Popis výsledku v původním jazyce

Human hair contains sulphur, which can be activated by fast neutrons. The 32S(n,p)32P reaction with a threshold of 2.5 MeV was used for fast neutron dose estimation. It is a very important parameter for individual dose reconstruction with regards to theheterogeneity of the neutron transfer to the human body. Samples of human hair were irradiated in a radial channel of a training reactor VR-1. P-32 activity in hair was measured both, directly by means of a proportional counter, and as ash dispersed in aliquid scintillator. Based on neutron spectrum estimation, a relationship between the neutron dose and induced activity was derived. Even if the hair activation method was proposed several years ago, it is not an ordinary practice. The main purpose of the experiment was to get practical experiences and verify the proposed method in practice.
