Mycosis fungoides is treated with radiotherapy in which radiation is irradiated on human superficial layer. The present study was made as a part of clinical basic experiments for this radiotherapy, i.e. for the purpose of obtaining homogenous distribution of the exposure dose on human body surface. For this purpose, a method was adopted, in which human body was made to rotate centering around the body axis and the irradiation beam was irradiated at a large field from a direction perpendicular to the body axis, and possible distribution of the exposure dose on skin surface was examined.Rediation was performed at a large field of 100×100 cm^2,using high-energy electron beam of 8 MeV. Exposure dose on skin surface was measured, using human body phantom. The results rerealed homogenous ddose distribution from the head to the knee region within an error limit of ±15%. The present method was considered to be useful for radiotherapy.
