| Research Abstract |
Several etched track detectors of PET, PC, PI and PADC films are exposed to proton and heavy ions, He, C, Ne, Si, Ar, Fe, Kr andXe ions, in the air. The examined region of stopping power was between 10 and 12,000 keV/μm. Chemical damage parameters of damage density, which is the number of loss of considering functional groups per unit length of tracks, radial size of track core, in which the considering chemical groups are lost, and the radiation chemical yields, G values, for each group are evaluated as a function of the stopping power. Latent track will be etchable when the radial track core size is larger than the distance between two adjacent breaking points of polymer chains. Such dominant breaking points are C-O bonds in ether, ester and carbonate ester bonds.
