摘要：

We studied the track response for the copolymer of CR-39 monomer with N-isopropylacrylamide (NIPAAm) as well as etching properties. It was found that copoly (CR-39/NIPAAm/Naugard 445) composed in weight ratio of 99/1/0.01 is highly sensitive to low LET particles in the region below 10 keV/mu m of LET200 eV and able to record normally incident particles of LET200 eV down to similar to 1.5 keV/mu m, recording protons up to the energy of 27 MeV. These results were compared with the responses for two types of CR-39 detectors containing a small quantity of antioxidant. The threshold energy of proton registration is discussed.
