Radiation in industry and research

Ionising radiation is employed in a number of areas in industry and research. Common to this use of radiation is that the radiation source is acquired for a special purpose, that is, it is wished to use the radiation actively in order to achieve some effect or other: for example, process control, materials control such as welding photography (industrial radiography), tracer studies, logging of wells in the oil industry, charge removal in car-painting and so forth.

When radiation is used in this way, there will always be an owner of the radiation sources, and the requirements imposed by the Norwegian Radiation and Nuclear Safety Authority (DSA) are primarily directed to such owners.

Administrative control of the use of radiation is performed at many levels:

  • Authorisation or use licensing. Acquisition and use of the sources require the permission of the DSA, which is granted on application, and presupposes that relevant radiation protection rules and requirements are observed. These requirements are usually issued as individual decisions in connection with the permits, or in the form of standardised “conditions” attached to the permits.
  • Inspections. From time to time the enterprises receive a visit from the DSA, which inspects the degree of compliance with the conditions for the licence.
  • Annual reports. Some kinds of enterprise with extensive use of radiation must submit an annual report as one of the conditions for the operating licence.
  • Accident reporting. The owner/user is obliged to report all accidents with radiation consequences to the DSA. 
  • Industrial radiography

    Industrial radiography entails the use of powerful radiation sources, often in open industrial premises or outdoors. Undertakings engaged in industrial radiography are therefore subject to specific requirements and official approval in accordance wit…

    Open radioactive sources/unsealed radioactive material

    Depending on the area of use and the amount of radioactivity, the use of open radioactive sources may subject to authorisation according to section 5 of the Radiation Protection Regulations, as well as a possible obligation to notification under sect…

    Radioactive sealed sources used in industry

    The installation and use of industrial sources normally requires only that Norwegian Radiation and Nuclear Safety Authority (DSA) is formally notified of the planned activity. If, however, the activity of the radioactive source exceeds a certain…

    Mobile radionuclide gauges

    There are several different kinds of mobile measuring equipment that utilise ionising radiation in the form of x-rays or gamma, neutron, alpha or beta radiation. Generally speaking, the radioactive sources used in this equipment are medium and low ac…
