Study on the long-term medical effects of radiation in overexposed people

To investigate the long-term effects of radiation exposure on health and provide empirical data for radiological research. The clinical symptoms, lens, cytogenetic, immune function and tumor incidence of 45 people exposed to ionizing radiation in the dose range of 0.02–1.36 Gy were observed. Compared with those of cytogenetic examination, lens opacity and tumor detection, the detection rate of lymphocyte micronuclei in the medical follow-up over-exposure group, interventional radiation group and nuclear medicine group was greater than that in the conventional radiation group, and the detection rate was the highest in the medical follow-up over-exposure group. There was a significant difference between the medical follow-up overexposure group and the interventional radiation group, and the differences among the medical follow-up overexposure group, the interventional radiation group and the conventional radiation group were statistically significant. Excessive exposure has certain effects on lens function, immune function and cytogenetics, and the detection rate increases with increasing dose, reflecting a certain dose‒effect relationship. Genetic damage can persist in an infected person, increasing the risk of cancer.
