We are members of two measurement networks associated with the International Atomic Energy Agency (IAEA):
Network of Analytical Laboratories for Measurement of Environmental Radioactivity (ALMERA)
Response and Assistance Network (RANET).
The laboratories are located in Østerås, Svanhovd and Tromsø. The laboratories perform accredited gamma ray spectrometry measurements. Our laboratories have several advanced instruments that measure radioactivity in samples with alpha, beta and gamma-emitting nuclides.
We carry out analyses and measurements, especially on seawater, rain water, seafood, seaweed, milk, soil and various animal species. Most measurements are carried out as part of established monitoring programmes and we also monitor radioactive contamination in the air.
DSA currently has six air filter stations located around Norway and the filters are analysed weekly for radioactivity.
Emergency Preparedness Laboratory
The Emergency Preparedness Laboratory ensures that there are instrumentation, expertise and procedures available to determine radiation levels in case of accidental nuclear events.
We perform measurements in order to identify and quantify nuclides in fallout, in people who potentially have radioactivity in their bodies and from contamination on people and equipment that may have been close to radioactive material and perform analyses of radioactive substances.
DSA also has a mobile laboratory that is readily available and transported by truck or aircraft if required.
The Radon Laboratory performs measurements of radon in indoor air with the purpose of mapping and monitoring to provide for knowledge-based management. We measure the radon concentration with etched-track detectors.
If you want to measure radon in your home: Radon measurements in residential dwellings. Unfortunately, DSA does not offer radon measurements.
The laboratory also measures natural radioactivity in water. Natural radioactive substances in the ground can be transported by both air and water. The laboratory analyses water samples for e.g. uranium, polonium and radon; see link to ‘Radon in water’.
The laboratory measures UV radiation, visible light and parts of the infrared spectrum, i.e. the 250 – 1000nm waveband.
The laboratory has three main functions:
We perform quality-assurance of UV data from the national UV network. We collect data and calibrate detectors in order to guarantee UV data of scientific quality.
We carry out measurements in connection with risk assessments of intentional and accidental exposure of people and products, test the classification of medical and cosmetic UV sources and laser pointers, calibrate sensors, etc.
We provide internal and external measurement services such as calibration and characterisation of detectors/sources, as well as developing new measurement procedures and devices.
