为了与相同暴露条件下估计的内吸收剂量进行比较，有必要估计暴露于喷洒的中子活化56MN粉末的实验动物的外吸收剂量，这是正确解释观察到的生物效应所必需的。确定了同一实验动物在相同条件下，伽玛照射所致外吸收剂量的测量范围为1-15mGy1-15mGy1个数量级，小于内照射和β照射全身的最大剂量：根据现有文献数据，小鼠全身内照射的最大吸收剂量为330mGy1200mGy1，大鼠为100mGy150mGy1个数量级。结果表明，在分散中子活化粉末56MnO_2的实验条件下，实验动物的内照射是辐射照射的主要因素，而外照射是辐射照射的主要因素。
Estimates of external absorbed dose in experimental animals exposed to sprayed neutron-activated 56Mn powder are necessary for comparison with internal absorbed doses estimated under the same exposure conditions, which is required for a correct interpretation of the observed biological effects. It has been established that the measured dose of external absorbed dose as a result of gamma irradiation range 1–15 mGy, which is order of magnitude less than the maximal dose of internal gamma and beta irradiation of the whole body of the same experimental animals irradiated under the same conditions: according to the available literature data, the maximal values of absorbed dose of internal gamma-beta irradiation of the whole body are in the range of 330 mGy–1200 mGy for mice and 100 mGy–150 mGy for rats. It is concluded that under the conditions of experiments with dispersed neutron-activated powder 56MnO2, internal gamma-beta irradiation of experimental animals is the main factor of radiation exposure compared to external gamma irradiation.
