The perennial cryolithozone is unique and one of the most complex environmental conditions on the Earth. This phenomenon is of global importance for the study of natural processes, as well as for the development and application of technologies in various industries, including oil production. Permafrost conditions are of significant interest to the oil industry due to their potential impact on a variety of activities, including infrastructure development, resource exploration and environmental management. The oil production industry is actively developing in areas of perennial cryolithozone, since proven oil and gas reserves are located precisely in such regions. However, one of the important factors that must be taken into account is the release of radon-222 gas in these areas. One of the aspects that require special attention in the field of oil production in the permafrost zone is related to the measurement of radon-222 flux density. In permafrost areas, measuring radon-222 flux provides a valuable tool for assessing potential risks and mitigating their impacts. Long-term exposure to radon-222 can lead to an increased risk of developing cancer in oil industry workers, especially those who are closer to sources of radon radiation. Radon-222 is released from the ground and can penetrate buildings, potentially exposing employee to increased levels of radiation. The article discusses the results of determining the flux density of radon-222 in order to ensure safe working conditions and health protection for employees of NK Rosneft - NTC LLC.
