PROBLEM TO BE SOLVED: To easily manufacture a point radiation source from radioactive solution including volatile radioactive substance without polluting the surrounding environment and an exhausting system.SOLUTION: A radiation source is manufactured inside a closed vessel 100 in which a radioactive solution suction and discharge device 120 and a radiation source supporting device 142 are installed, to minimize contact between radioactive solution 14 and the open air. An adsorption gas inflow system 200 and a gas circulation adsorption system 300 are connected to the closed vessel 100. Thus, it is possible to suppress radioactive gas generation in the closed vessel 100 and a gas adsorption tank 310 in the gas circulation adsorption system 300 is capable of adsorbing the radioactive gas generated in the closed vessel 100, to minimize pollution of the surrounding environment even if the closed vessel 100 is opened. |
