With the advent of the atomic age, a great deal of attention has been given to the effects of radiation of various types on the living organism. Some emphasis was placed also on the particular effects damaging radiation has on the central nervous system. Of particular importance was the dis -covery of the high resistance to irradiation exhibited by the central nervous system, and the observation of a latent period after exposure, during which the individual appears normal, followed by deterioration and death. Explan - ations of this unique reaction have caused some controversy and, currently, one of two theories are supported by most workers: (1) vascular damage is the primary cause of brain damage, precedes it, and causes necrosis; (2) direct damage is caused to nerve tissue by radiation and vascular damage is of secondary importance. Both theories have good supporting evidence as will be reported later.
