Facilities

	One of the chemical laboratories in the Research and Environmental Surveillance department.

STUK research is carried out at two different locations. Most of the research facilities locate in the main building in eastern Helsinki, and the rest at the regional laboratory in Rovaniemi, in northern Finland.

The facilities comprise a total of 50 laboratory rooms for pre-treatment of samples, radiochemical and biological treatment and analysis of samples.

STUK has seven laboratory rooms for low-background alpha, beta and gamma measurements. The rooms are constructed of a special concrete containing an extremely low amount of natural radioactive elements and are equipped with special air ventilation system. Also monitoring of temperature and humidity in the measurement rooms is arranged.

The main building also contains one laboratory for X-ray studies and three laboratories for the calibration of radiation measuring instruments. The laboratory facilities for cellular and molecular biology are isolated from the other research facilities. The laboratory for handling substances with high amounts of radioactivity is located in the sub-basement of the building.

Measurements of optical radiation, device testing and calibration are performed in an optical-laboratory and a solar-measurement chamber on the fenced roof. The interior of both the optical-laboratory and the solar chamber are black painted. The measurement site in optical laboratory is also screened by a black curtain from the rest of the room. Measurements of electric and magnetic fields, device testing and calibration are performed in radio-laboratory including a microwave anechoic chamber and SAR-measurement equipment.

The facilities of the Regional Laboratory of Northern Finland in Rovaniemi, used for pre-treatment, radiochemical analysis and measurements of environmental samples, comprises 7 laboratories and are located deep in the bedrock. The rooms for radioactive measurements (alpha, beta and gamma) are situated in a shelter and protected against electromagnetic pulses.
