Numerous studies are reporting the use of polymer composites as gamma-radiation shields. Different barite concentrations 0%, 10%, 20%, 30%, 40%, and 50% were added to epoxy, and the linear attenuation coefficients of the composites increased with the increase in barite concentrations (Al-Sarray et al. 2017 ). Abstract and Figures. To improve the physical properties of highly plasticized PVC, the polymer was crosslinked by gamma irradiation using a dose rate of 91 kGy/h. The effect of plasticizer type. Abstract In this paper, studies concerning the changes brought by gamma radiation on some PVC plates were made. The respective samples were exposed to gamma irradiation, at room temperature and different doses, such as (10, 20, 40, 80) kGy. The changes in the irradiated PVC plates' properties were studied by UV-Vis, electrical measurements, and SEM analysis on non-irradiated and irradiated. In this paper, studies concerning the changes brought by gamma radiation on some PVC plates were made. The respective samples were exposed to gamma irradiation, at room temperature and different.

Radiation shielding composites based on polyvinyl chloride (PVC) reinforced with different weight ratios of Pb(NO 3 ) 2 (5, 10, and 20 wt%) were prepared using the solution-casting technique. Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy, and tensile testing method were used to characterize the PVC. The use of gamma crosslinked plasticized PVC loaded with several particles has been proven to be useful materials for low dose ionizing radiation shielding (Nuñez-Briones et al., 2021) and similar materials loaded with tantalum carbide (TaC) are presented in this work. The gamma irradiation dose rate is evaluated during the crosslinking.
PVC is a glassy polymer well-known to be compatible with certain polymers to improve some properties for well-defined applications as an application in thermal aging conditions associated with gamma irradiations at nuclear centers. Often, this leaves sterilization by gamma irradiation as the most favorable alternative. 1. Unfortunately, exposure to gamma radiation has a negative effect on the appearance of flexible PVC. While physical properties and viscosity remain unchanged, immediately after sterilization the material tends to darken or yellow.

De vlakke plaat uit pvc is stevig en gaat minstens 5 jaar mee. Bevestig door te lijmen. Verkrijgbaar in verschillende afwerkingen en maten. Vaak samen gekocht Exposure of plasticized PVC to ionizing radiation, e.g., gamma rays or electron beam, causes changes in physicochemical and biological properties of material as described in the literature [62, 63]. The distinct discoloration of PVC occurs at a typical sterilization dose of 25 kGy; the material tends to darken or to turn yellow. This process is.
