“…In a minute by minute analysis of water and saccharin preferences following simultaneous exposures to saccharin solution and gamma rays, Smith and Schaeffer [16] found that the aversion starts within 15 min after exposure. According to McLaurin and co-workers [9], delayed offering of post-irradiation test fluid in deed influences the degree of response in saccharin avoidance be havior. The question of saccharin avoidance in mice has been broadly studied by the investigators mentioned above for a period of ten days to two weeks after the animals were exposed to ioniz ing radiation.…”
