SOME EFFECTS OF MIXED IONIZING RADIATIONS ON RHESUS PRIMATES EXPOSED UNDER LABORATORY CONDITIONS
Abstract
THE RADIOBIOLOIST HAS BE COCERNE WITH BOTH THE EARLY AN LATE EFFCTS O IOIZIN RADIATIOS ADMINISTERE IN SMALL INCREETS OR A RELATIVELY LONG PERIOD OF TIM. In 195, 48 Macaca mulatta primates were exposed to an irradiatio schele inolvin fast neutrons and gamma rays which resulte in the accumulation o doses from 7 to 614 rep. Since the exsure schedules afforde rest and recoery prios, it was proosed an f that the effects wre less severe than the effects from comparable doses given acutely. The principal early effct nted was a transiet decrease in pripheral cell counts for leukocytes and erythrocytes noted in the higher dose group. The principal late effects involved a reduction in visual acuity in the 307- and 614-rep grous; a series of deinitive, cotinuin behavioral changs; and evidence of dose-deendnt testicular damage as note by histopathologic methods. Evaluatio of the data susts that radiation was probably not a factor in life-shortening.
