Abstract
The moving irradiations, which aim to reduce the dose burden on the unit surface of the irrdiated skin and to convert the ray-bundle to the lesion, are devided according to the dose-distribution into three, namely, rotating, pendular and convergent method. The dose-distribution under the skin surface in these method is so complicated that the theoretical values very often fail to accord with actual ones. This is mainly due to the fact that the scattering rays, which are not very important in the static irradiations, are accumulated in the moving irradiations and have much to do with accumulated in the moving irradiations and have much to do with dose-distribution and that it is difficult to apply a certain mathmatical formula in order to get the accumulated doses. A beewax-phantom of the waist of a normal woman was made and the measurements were repeated to get as near doses to the actral value as possible using the excentric pendular rotating method.
