The results of experimental studies on the following problems in the high energy electron beam therapy were reported : 1. On the measurements of the outputs and doses. Problems in conducting the measurements on the ionization type dosemeters were examined ; and, also, problems in other dosimetry were investigated. 2. Measurements of the energy. The practical range method and the radioactivating method were studied. And the fabrication of simple energy checkers which may utilize magnets and their applications were described. 3. As the subject of study in regard to the dose distribution, the relationships of the dose distribution with such factors as the energy, scatterer, area of radiation field and the material and shape of the treatment cone were scrutinized, respectively. 4. The attempts at improving the dose distribution. Several approaches were made with the aim of extending as much as possible the range of theraputic capacity of the acceleretors with the definit upper limits on enargy. The principal aims of these attempts were to increase the depth dose, and particularly, to give an effective radiationto small focns.
