Effect of Solar radiation induced and alpha particles on Nonlinear behavior of PM-355 film

Abstract

Abstract In the current work of radiology, polymeric sheets of the PM-355 nuclear track detectors (SSNTDs) were exposed with α-particles and solar radiation for several exposure times. The absorption spectrum of samples exposed to the sun showed that the edge of the absorption accidentally changed to longer wavelengths. An investigation of continue waveguide laser effects on the nonlinear absorption properties of nuclear track polymer has been done. Non-linear absorption increases with increasing levels of exposure to sunlight and is highly connected to revealed surface morphology and chemical structural modifications. In case of high solar radiation flux and α-particles irradiation, the nuclear track detectors showed high nonlinearities, represented by the appearance of a number of diffraction rings.
