Tiivistelmä
A total of 3086 safety licences for the use of ionizing radiation were current at the end of 2017. The use of radiation was controlled through regular inspections performed at places of use, test packages sent by post to dental X-ray facilities and maintenance of the Dose Register. The Radiation and Nuclear Safety Authority (STUK) conducted 584 inspections of safety-licensed practices in 2017. The inspections resulted in 687 repair orders issued. In addition, radiation safety guides were published and research was conducted in support of regulatory control.
A total of 11 381 occupationally exposed workers were subject to individual monitoring in 2017 and 70 536 dose entries were recorded in the Dose Register maintained by STUK.
In 2017, regulatory control of the use of non-ionizing radiation (NIR) focused on lasers, sunbeds, radio appliances and cosmetic NIR applications. Two cases of sales or import of dangerous laser devices were found through regulatory control. Fifteen on-site inspections of show lasers were conducted. Municipal health protection authorities submitted the details of the inspections of 31 sunbed facilities to STUK for evaluation and decision. In addition to this, six sunbed facilities were surveyed on the basis of STUK’s own monitoring.
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 the calibration of radon meters used for measurement of radon in air. In measurement comparisons, STUK’s results were clearly within the acceptable range.
There were 112 abnormal events related to radiation use in 2017. Of these events, 25 concerned the use of radiation in industry and research, 84 the use of radiation in health care and three the use of non-ionizing radiation. In addition, 1085 events and near misses with an estimated minor significance for safety were reported for health care.
In 2017, nearly 7800 radon measurements at over 2000 workplaces were recorded in the national radon database. Radon concentrations detected in workplace measurements reported to STUK have decreased from the previous years. At conventional workplaces, the 400 Bq/m3 radon concentration was exceeded at approximately 13 per cent of the measured workplaces.
