Tiivistelmä
A total of 2 944 safety licences for the use of ionising radiation were current at the end of 2020, 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 the maintenance of the Dose Register. The Radiation and Nuclear Safety Authority (STUK) conducted 103 inspections of safety-licensed practices in 2020. The inspections resulted in ten orders to remedy deficiencies.
A total of 14 700 occupationally exposed workers were subject to individual monitoring in 2020. Around 72 600 dose entries were recorded in the Dose Register maintained by STUK.
In 2020, regulatory control of non-ionising radiation (NIR) use focused on laser equipment, sunbeds, mobile phones, UV torches and cosmetic NIR applications. As part of the regulatory control, online auctions of hazardous laser equipment were intervened in 22 times. Two on-site inspections of show lasers were conducted. Municipal health protection authorities submitted the details of the inspections of 26 sunbed facilities to STUK for evaluation and decision. In addition, five sunbed facilities were surveyed based on monitoring carried out by STUK. An inspection based on documentation was conducted on 24 beauty care facilities, and the radiation level of one laser device was measured in the place of use.
In metrological activities, national metrological standards were maintained for the calibration of radiation meters used in radiotherapy, radiation protection and X-ray imaging as well as radon meters used for measuring radon in the air. In measurement comparisons, STUK’s results were clearly within the acceptable range.
Research related to the use of ionising and non-ionising radiation produced new information on, among other things, the exposure of the lens of the worker’s eye and IPL (intense pulsed light) devices. This research also helped develop the regulatory control of nuclear medicine.
There were 57 radiation safety deviations related to radiation use in 2020. Of these events, 24 concerned the use of radiation in industry and research, 21 the use of radiation in health care, six the use of radiation in veterinary practices and six the use of non-ionising radiation. In addition, 1 541 events and near misses assessed to be of minor significance for safety were reported in health care, and five radiation safety deviations were compiled for summarized reporting in industry and research.
Over 17 000 radon measurements at around 4 400 workplaces were recorded in the National radon database in 2020. At conventional workplaces, the radon concentration exceeded the reference level of 300 Bq/m³ at approximately 13 per cent of the measured workplaces.
