Effects of the addition of MWCNT and ZrO nanoparticles on the dosimetric properties of PVDF.

The industrial application of radiation processing involves high doses of gamma or electron radiation to cause structural changes in materials, such as rubber vulcanization and polymer degradation, among others. A reliable dosimetric system is necessary to guarantee the desired effects and also to avoid damages. Poly(vinylidene fluoride) [PVDF] homopolymer has been recently proposed for application in high gamma dose dosimetry.

Very sensitive α-AlO:C polycrystals for thermoluminescent dosimetry.

New materials have been widely investigated for ionizing radiation dosimetry for medical procedures. Carbon-doped alumina (α-AlO:C) have been reported to be excellent thermoluminescent (TL) and optically stimulated luminescence (OSL) radiation dosimeters. In the present study, we have synthetized nano and micro-sized α-AlO:C polycrystals, doped with different percentages of carbon atoms aiming to compare their efficiency as TL dosimeters.
