Abstract
Many explorations have been done by our antecessors to find out about the congenital anomalies which might be caused by X-ray or γ-ray and experimental teratological researches have also been done, with some results. However, there have been less systematic studies on corpuscular radiation. Neutron ray is a radioactive ray no electrically-charged equally as photon (X-ray, γ-ray). With an equal dosage of it as photon's, its localized energy is high so that it is different in RBE. OER, etc. In heavy charged particle (proton ray. He ion, Ne ion, π-meson ray), there is the characteristic that the energy increases at around the deepest spot within the range rather than at the point of injection into a system, which is called Bragg peak. The type and energy of this radiation reflected in the uniqueness in energy distribution, in ionization density and in LET makes it the most important radioactive biological parameter. At this paper, we shall review the types of radioactive rays and discuss the congenital anomalies (teratogenecity) including the experimental results obtained by application of our proton ray.
