“…The PM-355 is a SSNTD and has the same chemical formula that of CR-39 or PADC. PM-355 SSNTDs have been widely used for the detection of ions [11][12][13][14][15]. Nouh and Bahammam have studied the effect of electron beam irradiation on PM-355 polymer within the radiation dose 20-250 kGy [13].…”

This work is based on the effect of different gamma doses with pre- and post-alpha-irradiated PM-355 polymer (polycarbonate of allyl diglycol). The phase crystallinity and structural analysis of the reference and irradiated PM-355 polymer were analyzed using an X-ray diffraction (XRD) study. It is revealed that the irradiation and etching reduce the %crystallinity but increase the crystallite size of the PM-355 polymer. The increase in crystallite size of PM-355 polymer after irradiation is supported by the scanning electron microscopic (SEM) analysis. The etching of the samples results in an increase in its track diameter. The optical band gap energy, measured by ultraviolet-visible (UV-VIS) spectroscopy, shows a decrement trend with the increase of gamma and alpha irradiation doses, and etching for all sets of samples under investigation. The number of carbon atoms per conjugation and per cluster has increased after gamma irradiation and etching. However, the increment is more pronounced for etched samples compared to nonetched ones. This indicates that etching results in a bigger size of cluster. Photoluminescence (PL) for both cases before and after etching has a dominant peak around 430 nm before and after irradiation, and change in peak intensity after irradiation confirmed that particle bombardment induced defects and clusters in the PM-355, which serves as nonradiative centers. The polymer can be used as a detector for gamma irradiation.

“…On the other hand, the modification of polymers by irradiation, either to achieve crosslinking or chain scission, is a significant industrial process throughout the world. Extensive studies have been performed to investigate this technology and thus the effects of radiation on the most significant classes of polymers are reasonably well understood . Kharazmi et al studied the structural, optical, and thermal properties of ZnS–PVA nanofluids synthesized using gamma irradiation.…”

Nanocomposite of polyvinyl alcohol (PVA) and zinc sulfide (ZnS) was fabricated by ex situ casting technique. ZnS nanoparticles were prepared by chemical coprecipitation method in air atmosphere using EDTA-ethylenediamine as stabilizing agent. Rietveld refinement of X-ray data showed that the prepared ZnS adapts cubic zinc blend structure with a lattice parameter fits 5.345 Å and a mean grain size of 4 nm. Samples from ZnS/PVA nanocomposite have been exposed to gamma doses in the range 0-400 kGy. The effect of gamma radiation on the structural and optical properties of ZnS/PVA has been investigated using XRD and UV-Vis spectroscopy. The absorption spectra confirm the formation of hybridized film ZnS/PVA nanocomposite with refractive index in the range of 1.3123-1.5253 (at 700 nm). Also, the gamma radiation reduces the optical energy gap from 4.58 to 2.75 eV. This could be attributed to the increase in structural disorder of the irradiated ZnS/PVA nanocomposite due to the formation of coordination reaction between OH of PVA and ZnS nanoparticles. This means that the gamma radiation led to a more compact structure of ZnS/PVA nanocomposite and causes proper dispersion of ZnS nanoparticles in the PVA matrix. Further, the Commission Internationale de E'Claire (CIE units x, y, and z) methodology was applied for the description of colored samples. The color intensity ΔE, the color difference between the non irradiated sample and the irradiated ones, was increased from 1.39 to 11.18 with increasing the gamma dose up to 400 kGy.
