It is known that 40%-75% common doze of people’s exposure by natural radioactive sources comes from radon and its decay products based on the International Committee on Radiation Protection. In 1987, radon and its decay products were identified by experts from the International Agency on Cancer Research as a group of carcinogenic elements threatened for humans. Currently, people protection from radioactive natural gas exposure is the important problem necessitating to conduct a number of researches to reveal the radon sources, to define its quantity in populated points. Indoor radon studies in Azerbaijan were carried out firstly during 2010-2011. Within 2014-2015 the investigation of radon problem in Azerbaijan continued in the framework of Azerbaijan state program for the covering period of 2014-2018. The paper describes results of correlative analysis between the rates of lung cancer among the population and radon distribution in Azerbaijan. Correlation coefficients for 2012-2015 vary from 0.5 to 0.8, which indicates an obvious correlation between high levels of radon concentration and lung cancer risk.
