Groups of male opossum (Didelphis virginiana) at 6 months of age were exposed to 350, 500, 550, 600, 650, 700, and 750 rad of whole-body60 Co radiation at a midline dose rate of 125 rad/min. The 30-day LD50 was 511 rad with 95% confidence limits of 454 to 576 rad. The overall mean survival time was 17.9 days and the highest incidence of death occurred on the 16th day.
