天然~(C4)C在人体脂肪组织中建立了最大的吸收剂量(40μGy·a~(-1)),当前把它作为~(14)C的险要组织,红骨髓中的吸收剂量虽为26μGy·a~(-1),比脂肪组织低0.5倍,但红骨髓的放射敏感性却比脂肪组织高2倍,因此,~(14)C的险要器官应当是红骨髓,~(14)C的年摄入量限值(НРП)应进行修订。核电站周围居民(Б组)~(14)C主要随食物进入人体,在局部源所处地区的空气、食物、人体中,~(14)C存在着浓度平衡。这样, НГП=П天然·ПД/Д天然式中,НГП为按某器官剂量计算的~(14)C年摄入量
Natural C4C has the highest absorption dose (40μGy · a -1) in human adipose tissue. At present it is regarded as an important tissue of ~ (14) C, and the absorbed dose in red bone marrow is 26μGy · A ~ (-1), which is 0.5 times lower than that of adipose tissue, but the radiosensitivity of red bone marrow is 2 times higher than that of adipose tissue. Therefore, the key organ of ~ (14) C should be red bone marrow, ~ (14) C The annual intake limit (НРП) should be revised. Residents around the plant (group Б) ~ (14) C mainly enter the human body with food, and there is concentration balance of ~ (14) C in the air, food, and human body in the area where the local source is located. Thus, НГП = П natural · ПД / Д natural type, НГП is calculated according to an organ dose ~ (14) C annual intake
