Tiivistelmä
A total of 2 887 safety licences for the use of ionizing radiation were current at the end of 2021, in addition to three safety licences for aviation operations. The use of radiation was controlled through regular inspections performed in places of use, regulatory control queries, and maintenance of the Dose Register. The Radiation and Nuclear Safety Authority (STUK) conducted 137 inspections of safety-licensed practices in 2021.
A total of 13 660 workers were subject to individual monitoring in 2021. Around 76 500 dose entries were recorded in the Dose Register maintained by STUK.
In 2021, the regulatory control of non-ionizing radiation (NIR) use focused on laser equipment, sunbeds, mobile phones, torches and cosmetic NIR applications. As part of the regulatory control, STUK intervened four times in online auctions of hazardous laser equipment. Two on-site inspections of show lasers were conducted. Municipalities’ health protection authorities submitted the details on inspections of 18 sunbed facilities for STUK to evaluate and make decisions on. In addition, four sunbed facilities were supervised based on monitoring carried out by STUK. An inspection based on documentation was conducted on 25 beauty care facilities. The radiation levels of ten mobile phones were checked during the year. In metrological activities, national metrological standards were maintained, and radiation meters used in radiotherapy, radiation protection and X-ray imaging as well as radon meters used for measuring radon in the air were calibrated. In measurement comparisons, STUK’s results were clearly within the acceptable range. As a significant recognition of the Dosimetry laboratory, STUK was accepted as a member in the the Dosimetry section of the Consultative Committee for Ionizing Radiation (CCRI) of the International Committee for Weights and Measures (CIPM).
STUK was accepted as a participant in a research project coordinated by the IAEA which aims to examine the need to update dosimetry practices in X-ray imaging.
There were 42 radiation safety deviations related to radiation use in 2021. Of these incidents, 21 concerned the use of radiation in industry and research, 18 in health care and one in veterinary practices. Two incidents were related to the use of non-ionizing radiation. In addition, 2 434 incidents and near misses assessed to be of minor significance for safety were reported in health care, and a summarized notification was submitted of four radiation safety deviations in industry and research.
Over 12 000 radon measurements at around 3 000 workplaces were recorded in the national radon database in 2021. At approximately 14% of the measured conventional workplaces, the annual average for radon concentration exceeded the reference level of 300 Bq/m³. One safety licence was granted to an underground construction site where reducing radon concentrations was not possible.
