説明

Registration of α-tracks and fast-neutron-induced recoil tracks by the electrochemical etching (ECE) technique as applied to sensitive Lexan polycarbonate foils has provided a simple, sensitive, and inexpensive means of neutron dosimetry. The application of this ECE technique to the amplification of alpha particle tracks in 250-μm-thick Lexan polycarbonate foils was studied here. The intention is to produce permanently stable tracks which are suitable for α particle detection.<br>The detection efficiency for α particles as a function of etching time under conditions of 1, 000V, 2kHZ, 22°C, and 50% alcoholic KOH solution was shown. It seems that the track registration efficiency is not proportional to the specific ionization in the polycarbonate foil. From the study on the relative frequency of track diameter distribution it is evident that the track diameter depends only on the latent track position in the foil.
