摘要
狗在受到2Gy 裂变中子照射时,用含硼橡胶屏蔽身体的不同部位,可以减轻其辐射损伤。屏蔽狗的头颈部,可减轻由于中子对口腔粘膜直接损伤作用而产生的大片溃疡。屏蔽腹部可使早期胃肠反应症状消失、早期白细胞水平升高。屏蔽骨盆部或下腹+骨盆部,使受照射动物多数临床症状和外周血像改善,病情减轻最明显,活存率最高。屏蔽腹部、骨盆部及下腹+骨盆部,可使无屏蔽时的重度骨髓型急性放射病减轻为中度骨髓型急性放射病。
Dogs were irradiated by fission-neutron in dose of 2 Gy.Shielding of different parts of body by horonrubber,might alleviate the radiation damage. Shielding of head and neck could mitigate the ulceration of oral mucosa as a result of direct neutron injury.When the abdominal area was shielded the early symptoms of diges- tive tract disappeared and the WBC counts of the peripheral blood increased in the early pe- riod after exposure. Shielding of the pelvis or lower abdomen plus pelvic area had the best protective effects, the degree of damage decreased significantly,the survival rate was the highest,and there was only moderate hematopoietic type of acute radiation sickness.
