Direct Registration of an Instantaneous X-Ray Effect in Rats and Man


IN order to study chemoprotection against radiation damage we tried to find radiobiological reactions as near as possible to the primary radiochemical process. In this we were guided by the assumptions that we must look for this in macromoleeular systems and that we might find most radiosensitivity outside the domain of natural chemoprotection against oxidative or reductive radicals, that is, the respiring cytoplasm.
