Kgy gamma radiation
Web27 feb. 2016 · We report the first observation of a significant gamma radiation-induced blue shift of the reflection/transmission peak of fibre Bragg gratings inscribed into pure-silica core fibres via multiphoton absorption of femtosecond pulses. At a total dose of ~100 kGy, the shift is ~20 pm. The observed effect is attributable to the ionising radiation-induced … WebAbeBooks.com: Post harvest preservation of Cucumis sativus through gamma irradiation: Quality control and shelf life extension (9783659748967) by Bashir, Naila; Abdullah, Roheena; Naz, Shagufta and a great selection of similar New, Used and Collectible Books available now at great prices.

Quercetin was gamma-irradiated at doses of 0, 15, 30, 50, 100 and 150 kGy, which induced new radiolytic peaks (the highest radiolytic peak at a dose of 30 kGy).Treatment of intact- and gamma-irradiated quercetin did not induce a significant …
WebThe main objective of this study was to examine the potential of gamma ray irradiation with various radiation doses in improving the mechanical and thermal properties of WPC. Gamma ray irradiation was carried out at doses of 0, 25, 50, 75, and 100 kGy at a dose rate of 3.5 kGy/h using a 60Co source. WebThe reduction methods were Aloe vera extract and gamma ray irradiation with a dose rate of 0.756 kGy/h and a total dose of 40 kGy from a 60Co-source. The chemical species of the nanoparticles (NPs) obtained by Aloe vera extract were Ag, CuO, and ZnO; while the NPs obtained using gamma irradiation were Ag and Cu2O.
WebThe nutrients contents in red pepper were respectively 98.6% and 92.3% for total phenol, and 97.8% and 94.5% for beta-carotene, right after irradiation at the dose of 10 and 20 kGy. The vitamin C contents decreased with irradiation doses up to 76.4% (10 kGy) and 68.5% (20 kGy) and B1 contents decreased to 54.9% and 80.7% of non irradiated red ...
WebThe ionizing radiation promotes chain scission and creates free radicals which can recombine, providing their annihilation, for crosslinking or branching.
