Application:

Constant sampling of ground level aerosols on Petryanov FPP-15-1.5 air filters. Weekly basis. Low background gamma ray spectrometry are used for determination of radioisotopic composition in dust, in quantitative (in Bq/m3) as well as qualitative way. Besides own ASS-500 at the Institute there are operating instruments, which belongs to Polish environmental radioactivity monitoring system: another ASS-500 sampler and PMS station. They are property of PAA and CLOR. In radiometric ground there is also a precipitation collector with active area of 2,2 m2.
