Radioactivity Measurements Laboratory
Using Cs-137

Equipment

Canberra HPGe coaxial gamma spectrometer (on the left) for the measurements of the natural concentration of radionuclides for estimating the annual dose. On the right, a HPGe well-type gamma spectrometer can be seen. It is mainly used for the determination of the radionuclide concentration in small samples.

The Laboratory offers measurement of the both natural and artificial radioisotopes in environmental samples and buildings materials. The Laboratory offers also the determination of the annual dose for OSL an TL dating.

The laboratory consists of a room for preparation for handling samples with necessary equipment and gamma spectrometry laboratory for measurements of nuclide content of samples. The laboratory of low radioactivity has also the equipment for sampling (e.g. 2.5 m soil corer).

The Low Radioactivity Laboratory is equipped with two high resolution gamma spectrometers of coaxial and well type. Both spectrometers are equipped with high purity germanium detectors. The efficiencies of the detectors are 35% and 12%, respectively. The spectrometers allow the measurement of activity in samples. The supplied software allows rapid analysis of the data.
