title: [Ways to reduce radiation doses caused by radon during exploration of gas and oil fields in the North].
abstract: Analysis of literature data and the personal studies of oil and gas extraction enterprises proved that the radiation environment depends mainly on natural radionuclides (uranium-238, thorium-232, potassium-40) incorporated into soil, deposit water, oil, gas and construction materials. Radioactive barytic accumulations in compressor pump tubes appeared to b a possible cause for significant background gamma-irradiation (up to 3,000 microR/hr and more; Neftekoumsk town of Stavropol area). Major radiation dose received by personnel in such cases results mainly from radon-222 and its derivatives, that should be considered in placement of living area, location of industrial and special compartments, water extraction sites. The places with minimal rate of radon emission are recommended for such purposes. To decrease radiation doses associated with gas and oil extraction in the North, the authors suggested a scheme of radiation control and listed all the equipment necessary.
