Comparative analysis of some radiosensitivity index results of certain radiation workers in Chongqing from 2018 to 2019

objective This paper analyzes the physical examination results of blood routine, chromosome deformity rate, micronucleus rate and thyroid function test of some radiation workers in Chongqing from 2018 to 2019, understands the occupational problems of radiation workers, and provide scientific basis for putting forward reasonable suggestions method:Methods 2656 cases in 2018 and 2922 cases in 2019 were selected through the information platform of physical examination system. A total of 5578 physical examination results in two years were statistically analyzed and analyzed.Results The abnormal rate of blood routine, the detection rate and abnormal rate of chromosome distortion and micronucleus, and the abnormal rate of thyroid gland function (T3, T4, TSH) between the control group and the radiation group are significant differences (P < 0.05). There were significant differences in the abnormal rate of blood routine, thyroid function (T3, T4, TSH), chromosome teratosis rate, micronucleus detection rate and abnormal rate between radiation diagnosis and treatment and industrial flaw detection, but there was no significant difference in the abnormal rate of chromosome (P > 0.05). There was significant difference between < 10 year group and 10 ～20 year group, and there was significant difference in platelet, white blood cell and hemoglobin between 10 ～20 year group and 20 year group (P < 0.05). There was no statistical significance in erythrocyte difference (P > 0.05). There was significant difference in the abnormal rate of thyroid function among the three working age segments (P < 0.05). The detection rate of chromosome distortion was significantly different between < 10 years group and 10 ～20 year group (P < 0.05), but there was no significant difference between the other two groups (P > 0.05). There was significant difference in the abnormal rate between the two groups (P < 0.05). There was no significant difference in pairwise comparison of micronucleus detection rate among groups (P > 0.05), but there was significant difference in abnormal rate among groups (P < 0.05).Conclusion The long-term low dose ionizing radiation environment will damage the hematopoietic and endocrine system of radiation sensitive human body.
