Abstract Residential Radon Exposure and Lung Cancer: A Survey in Chiang Mai Province

§Chiang Mai Provincial Health Office, ^#Academy of Science, the Royal Institute, Bangkok

This survey was conducted in four districts in Chiang Mai Province as part of a multidisplinary research study by academic staff of three universities, namely Chiang Mai, Songkhla and Khon Kaen university, in collaboration with researchers from the Thailand Institute of Nuclear Technology and the Royal Institute, with the aim of verifying the association between residential radon exposure and lung cancer risk. The study was carried out by measuring radon gas levels in the homes of proven cancer patients and in other homes as controls for the purpose of comparison. As the findings in both categories of residences showed that the radon levels did not exceed the safety threshold (148 Bq/m³), it was con- cluded that radon gas exposure in such a situation of low levels would likely not be a significant cause of lung cancer, but rather attributed to the heavy smoking habit of the northern citizens.

Key words: radon gas, lung cancer
