“…For this purpose, PM-355 sample irradiated with α-particles was selected. N and M values of the PM-355 nuclear track detector film used in present work are compared with materials known to have proven to be a sensitive nuclear track detector by having a good carbon atoms per conjugation length value such as (N=5.4, M=106) [22], (M=80 ) [23], (N=4, M=67) [24], (N=~5 ) [25], present work (N=~5, M=90.77), All the values for the PM-355 nuclear track detector above are measured before etching time except present work has been done under etching time. It is noticed that the PM-355 nuclear track detector film has a carbon atoms per conjugation length (N) and the number of the carbon atom per clusters (M) values large than these detectors, which means that our technique have a better SSNT detectors properties compared to these materials.…”

The imaging processing technique was used for studying a laser beam nature that transmitted through films of PM-355. The thermal nonlinearity of PM-355 films was studied using a 635 nm cw diode laser at 15 mW as the source of excitation. Third order nonlinear optical properties of PM-355 films irradiated with α-particles at different times and pristine sample has been studied using Z-scan technique. The samples showed a negative and large nonlinear refractive index and reverse saturable absorption (RSA) with high values of the nonlinear absorption coefficient. The fluorescence spectra of PM-355 films were investigated at room temperature and wavelength range of 250–500 nm for a pristine film and in different times of exposure to α-particles. The broad peaks were between 350, 420 and 465 nm. All-optical switching property of PM-355 samples irradiated with α-particles at 20 min was also studied using the standard pump-probe technique.

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.
