Chemical damage parameters of damage density, which is the number of loss of considered function groups per unit length of tracks, effective track core radius, in which the considered chemical groups are lost, and the radiation chemical yields, G values, for each group are evaluated as a function of the stopping power. The chemical damage parameters for the losses of ether and carbonate ester bonds in PADC are hardly affected by the environmental conditions in the cases of He and C ion irradiations whether irradiated in air or in vacuum. The yield of OH group formation was fairly suppressed in vacuum irradiations, compared to that in air.}, pages = {178--179}, title = {Damage structure along heavy ion tracks in solid state nuclear track detectors}, volume = {NIRS-M-273}, year = {2014} }
