切尔诺贝利核电站事故病人外照射剂量与外周血淋巴细胞数间有一定的相关性.发现照后第1天无明显相关,第2天有相关倾向,第3至第6天相关性良好.但用3～6天的淋巴细胞平均数预测急性放射病严重程度的准确率仅50%～52%,而配合相邻组病人临床表现预测的准确率达88%.因而,推测人外周血淋巴细胞至少是由辐射敏感性不同的两部分组成,D_0值分别为0.43Gy和5.47Gy.
There was a certain correlation between the dose of external exposure and the number of peripheral blood lymphocytes in Chernobyl nuclear power plant accidents.It was found that there was no significant correlation on the first day after irradiation, the relative tendency on the second day and the correlation on the third to the sixth day However, the accuracy of predicting the severity of acute radiation sickness was only 50% -52% with the mean lymphocyte count of 3-6 days, while the accuracy of predicting clinical manifestations with adjacent group was 88% .Therefore, it is speculated that human peripheral blood lymph The cells consisted of at least two parts with different radiosensitivity with D_0 values of 0.43 Gy and 5.47 Gy, respectively.
