Changes of the peripheral blood picture after combined neutron and gamma irradiation

Changes of the peripheral blood picture of rats irradiated with a single dose of 2 Gy of neutrons were followed in comparison with a group of rats irradiated with a single dose of 2 Gy of neutrons followed by continuous gamma irradiation (daily dose rate 0.574 Gy, total dose 6 Gy). The decisive factor for the organism damage was the single 2 Gy neutron dose. The subsequent continuous gamma irradiation retarded the reparation of the peripheral blood elements.
