Abstract
The comparative study of three differnt types of fast neutron dosimeters based on solid state nuclear track detectors is presented; the dosimeters studied were: • microscopic soda glass in contact with 232Th; • polycarbonate Makrofol E; and • cellulose nitrate Kodak LR 115. All detectors were evaluated by visual counting in a microscope. We have studied such properties as the background, angular as well as energetical dependences of detectors. The results obtained show that all studied detectors are suitable for fast neutron dosimetry; their application depends however on the concrete experimental conditions (neutron spectrum, fluence etc.). We present both advantages and disadvantages of each of them.
