SHIELDING MEMBER FOR RADIOACTIVE SUBSTANCE, MANUFACTURING METHOD FOR THE SHIELDING MEMBER AND APPARATUS FOR PRODUCING RADIOACTIVE SOLUTION

摘要

The present invention provides a shielding member for radioactive substance which can be made compact in size and light in weight with maintaining its shielding ability, or improve the shielding ability while being kept in the same size thereby to store a large volume of radioactivity. At the same time, the present invention provides a manufacturing method for the above shielding member and a radioactive solution-producing apparatus using the above shielding member. The radioactive substanceshielding member uses two or more kinds of radiation shielding materials of different shielding abilities. A shielding body (51) made of a shielding material of the highest shielding ability is arranged at an area (5b) which is the nearest to a radioactive source.
