Among various existing techniques, registration of fast-neutron-induced recoil and (n,..cap alpha..) particle tracks directly in sensitive polymers such as polycarbonate foils provides a simple, sensitive and inexpensive means of fast neutron personnel dosimetry when recoil tracks are electrochemically etched. Some characteristics of this technique, including dose range, directional response, energy dependence, fading characteristics, etc. are reported. This technique has a wide dose range of interest for routine and accidental personnel dosimetry. It is insensitive to high doses of x, beta, and gamma radiation and it has negligible fading over a long period of time. The large size and good contrast of the tracks make track density evaluations very simple. The track density obtained can be simply converted to dose equivalent (rem) using a conversion factor which is a constant over a neutron energy range between 1 to 20 MeV. The technique is a good alternative to NTA films and fission fragment registration techniques and it can be applied to a number of applications especially fast neutron personnel dosimetry.
