Abstract

OBJECTIVE: To explore the relationship between low dose radiation and leukemia and assess resultant risk of leukemia. METHODS: The leukemia incidences (1950 - 1995) in 27,011 medical diagnostic X-ray workers and in 25 782 non-radiation workers in hospital employed between 1950 and 1980 in China were compared by O/E system. RESULTS: The relative risk (RR) of leukemia in the medical X-ray workers was 2.17 (95% CI = 1.58 - 2.91, P < 0.01). The highest RR of leukemia was found in those who engaged in X-ray work before 1960 or at age under 20 years. CONCLUSION: There was a relationship between incidence of leukemia and X-ray radiation in X-ray workers and accumulation of radiation dosage and employment at younger age increased the risk of leukemia.
