To investigate whether low dose ionizing radiation caused perturbation of peripheral blood lymphocytes in radiology unit staff, the T-helper/suppressor ratio was examined in eight radiologists exposed to low dose radiation over a period of 6 to 27 years (mean 12 years). No significant difference was noted in the T-cell subsets between exposed radiologists and non-exposed control subjects. The effect of low dose ionizing radiation on peripheral blood lymphocyte subsets seems to be virtually negligible. Further, measurement of the T-helper/suppressor ratio is not a reliable way of demonstrating any damage to bone marrow caused by low dose ionizing radiation.
为了调查低剂量电离辐射是否会导致放射科工作人员外周血淋巴细胞紊乱，研究人员对8名在6至27年（平均12年）期间暴露于低剂量辐射的放射科医生的辅助性T细胞/抑制性T细胞比例进行了检测。暴露组的放射科医生与未暴露的对照组受试者之间的T细胞亚群没有显著差异。低剂量电离辐射对外周血淋巴细胞亚群的影响似乎实际上可以忽略不计。此外，测量辅助性T细胞/抑制性T细胞比例并不是证明低剂量电离辐射对骨髓造成任何损伤的可靠方法。
