Medaka/Chronic ƒÁ-irradiation/Fecundity /Fertility Eggs of the medaka, Oryzias latipes, were irradiated continuously with 137Cs ƒÁ-rays at exposure-rates of 10, 100 and 1000 R/day from the morula stage to hatching. Newly hatched fry were transferred to non-irradiation field. At one year after hatching medaka were tested for their fecundity and fertility. When irradiated females were mated with ...
