Chemical effects of gamma radiation on iodine in aqueous solutions

摘要: Abstract Gamma radiolysis of iodine ions in aqueous solutions was investigated under high intensity gamma-rays (at 4.5 × 106 R/h) from 60Co at ambient temperature. The yields radiation induced oxidation products, I2 and IO3− were measured as a function dose, I− concentration solution pH. yield increased with increasing decreasing G(I2) value is determined to be 0.2 pH 2 containing 10−3 MI−. At an iodide 10−5 M or less, the formation diminished, whereas found. Iodide converted nearly quantitatively hwern initial 10−6 less range 3 9. maximum G(IO3−) 0.001 8 solution.

Experimental data have demonstrated that iodate BWR coolant result effects on radioniodine coolant. would predict steam phase probably distillation volatile
