The effect of a grid on whole-body megavoltage radiation tolerance in C3Hf/SED mice was studied. Adult mice were irradiated beneath a 50% megavoltage grid. LD50 (50% lethality) values were measured at ten and 30 days. LD50/30 day increased by a factor of 1.5 for mice receiving both single and two fraction irradiation beneath the grid. LD50/ten day increased by factors of 1.1 to 1.2 for single, two, and five fraction irradiation beneath the grid.
