Commissioning dosimetry and in situ dose mapping of a semi-industrial Cobalt-60 gamma-irradiation facility using Fricke and Ceric-cerous dosimetry system and comparison with Monte Carlo simulation data

Complex Long-term Effects of Radiation on Adult Mouse Behavior

“…At the age of 10 weeks (± 10 days), groups of 20 mice per sex and genotype were whole-body irradiated by doses of either 0.5, 1 or 2 Gy (dose rate 0.3 Gy/min; 60 Co source in Eldorado 78 tele-therapy irradiator, AECL, Canada). This 60 Co source is one the most widely used sources γ-radiation 27 . Concurrently processed control animals (in total 21 mice per sex and genotype, 7 accompanying each radiation dose group), had the same type of handling and other conditions of exposure, but without dose (sham radiation, 0 Gy group).…”

Dose mapping of products with different density irradiated in 60co irradiation facility of the Vinca institute, Serbia

“…Boxes with plas tic ma te rial are 43 cm high and filled to the top. Box has a vol ume of 0.091 m 3 . The weight of the prod uct with out the box is 15 kg, so the av er age den sity of the prod uct is 164.8 kgm -3 .…”

“…Dose map ping in dif fer ent ir ra di a tion fa cil i ties has been de scribed in sev eral pa pers [2][3][4]. How ever, due to the spe cific con struc tion of the irradiator at the Vin~a In sti tute, it is ex tremely im por tant to per form dose map ping for prod ucts of dif fer ent den si ties.…”

Water Radiocatalysis for Selective Aqueous-Phase Methane Carboxylation with Carbon Dioxide into Acetic Acid at Room Temperature

“…The optimal reaction condition of the 420 mL reactor containing 40 39 that the •OH radicals preferentially attack the weakest C−H bond of hydrocarbon molecules, such as the CH 2 group of C 3 H 8 and C 4 H 10 , to form the •CH(CH 3 ) 2 and •CH(CH 3 )CH 2 CH 3 radicals, respectively. The liquidphase products were barely observed when the hydrocarbon + H 2 O mixture was irradiated with γ-rays; meanwhile, the CO 2 conversion rates were much faster for the hydrocarbon + CO 2 + H 2 O mixture irradiated by γ-rays than for the CO 2 + H 2 O mixture irradiated by γ-rays.…”

“…Activity Measurements. Catalytic performance evaluations were carried out at the 60 Co γ-radiation facility (Figure S16) 40 located at the University of Science and Technology of China with a radioactivity of 1.37 × 10 15 Bq. The 60 Co source was stored in a pool of water used as a shielding material, surrounded by concrete barriers to prevent the operators and the public from being exposed to radiation.…”
