Effect of the low dose radiation pre-exposure on blood's reaction and survival of animals which were then exposed to high level radiation or combined radiation and thermal injuries

CBAxC57BL6 mice pre-exposed to 5 cGy gamma-irradiation then inflicted to LD70/30 acute radiation or combined injuries (radiation + thermal burn). In such protocol of the experiments preliminary adaptive dose radiation did not modify low 30-day survival rate and did not render an influence to the mean survival time. Leucopenia level and bone marrow devastation in 3 days after sublethal irradiation (4 Gy) and in their unexposed controls. Adaptive dose radiation decreased leukocytes number within the phase of hemopoiesis recovery (in 14 day after sublethal irradiation or combined injury)
