Chromosome aberration frequencies in the peripheral blood lymphocytes have increasingly been used for the study of the effect of various occupational and environmental mutagens. In the south of China there is a high background radiation area (HBRA) where the level of natural radiation is 3 to 5 times higher than control areas (CA). The level of natural radiation at HBRA is high due to radionuclides such as Thorium 232 and Uranium 238 decay products in the soil and in the building materials of houses. The elevated dose rate level of natural radiation in HBRA is about equal to that of routine chest X-ray examination of about once a week. To determine the effect of low-dose radiation on human health, we analyzed the chromosomes of peripheral lymphocytes of the residents in the HBRA and compared the results with those obtained from the residents in a control area in Guangdong Province and in Beujing.
In the present paper we review our cytogenetic studies performed in the above 3 places and discuss the effect of low dose radiation on human health. All the results presented here were obtained by the Chine-Japan collaborative study on the HBRA conducted by Prof. Tsutomu Sugahara, Japan, and Prof. Luxin Wei, China.
