Description

Rugged design, direct reading personal electronic dosimeter for monitoring of exposure to gamma and neutron radiation. The principle of neutron detection allows to calculate correct dose value regardless of the neutron emission spectrum. Distinctive features and detection principal: Measurement of personal dose equivalent Hp(10) of neutron radiation is performed using two measurement channels: the channel for albedo thermal neutrons (neutrons moderated in the body and that escape the body in the area where the dosimeter is worn) and the channel for fast neutrons, directed to the body from outside. In the albedo channel, the dosimeter registers alpha particles from lithium target due to 6Li(n,α)3H reaction (the target is placed on the surface of silicon detector). Fast neutrons are registered by recoil protons that appear in the polyethylene target due to elastic scattering of fast neutrons (the target is placed on the detector). Dose equivalent Hp(10) is calculated according to special algorithm taking into account measurement information from both “albedo” and “fast” channels. Thanks to the presence of two measurement channels, the dependence of sensitivity on neutron energy of the DVS-02D is far less when compared with other measurement methods, that makes it possible to use the dosimeter for personal exposure monitoring in the fields of Pu(Be), Po(Be) and other neutron sources as well as near nuclear reactors, without preliminary estimate of neutron spectrum.
