Abstract

Utilizing the advantage of the Tracer-encapsulated Solid Pellet (TESPEL) injection method, the radiation power emitted from heavy atoms such as tungsten is measured knowing the total amount of the heavy atoms. The experimentally obtained radiation power is compared with the theoretical calculations. The TESPEL method is found to be useful for evaluating the absolute radiation power from the heavy atoms, although the present status is preliminary and further data should be accumulated.
