Abstract
An apparatus for chemical reaction by irradiation of materials in liquid phase with Kr-85 as the source is devised. Circulation of bubbling Kr-85 gas through the reactant facilitates the reac-tion. In this method, the dose rate is controlled by changing the fractional void and concentration of Kr-85 gas. When 1000 ml of water was used as the reactant with 40% fractional void and5% concentration of the gas, use of 200 curies of Kr-85 gave the dose rate of 2.8×104rad/h at 60°C and 0.9 atm pressure.
