RESUMEN
The first studies of radiation exposure in old mines of Kryvyi Rih Iron Ore Basin (Kryvbas) began relatively recently, about 20 years ago. The results of these studies have shown that the problem of radon is present in the major part of the Basin mines. In 6 of 8 mines tested, an excess of radiation safety standards for the equilibrium equivalent decay products concentration (EEC) of Radon-222 was observed. According to the sum of the main measured parameters of radiation situation, a preliminary assessment of doses to underground workers was made and a classification of the Basin mines according to radiation danger was developed. Results of the recent radiation surveys of these mines are shown in this article. Data on the incidence of lung cancer among the miners are presented and classified into age groups. Measures to improve the radiation situation in the mines of Kryvbas are considered.

The town of Zhovti Vody is a 'capital' of uranium mining and processing industry of Ukraine. The mining and processing of uranium has been carried out in this area for more than 60 y. During this period, due to increasing production activities, the town has grown significantly. As a result of production activities and also due to the human factor, the territory of the town was contaminated by radioactive rocks. In addition, out of ignorance, radioactive rocks were used in the construction of houses and roads. To normalize the radiation situation in the town, a targeted State Programme was adopted in 2003 for a period of 10 y. In 2013, the Programme was subsequently extended until 2022. In accordance with this Programme, decontamination of the urban territory, measurements of radon isotopes in houses and anti-radon reconstructions of the premises have been performed. The results of these works are described in this article.
