Current issues

The Radiation and Nuclear Safety Authority will measure the radioactivity of students and staff at the Kumpula campus of the University of Helsinki this week. Measurements will be carried out in Tampere next week and in Rovaniemi after the turn of the year.

People who use radiation in their work are mostly satisfied with the Radiation Act and the regulations clarifying the Act. However, according to a survey conducted by the Radiation and Nuclear Safety Authority, there is still room for improvement in the provision of information and instructions.
