The investigations of rare nuclear decays and low probability interactions of radiation with matter contributed in the last decade significantly to the development of "new" physics beyond the standard model of fundamental interactions. Most of the advances in the field of "non-accelerator" nuclear physics and astroparticle physics depend on background reduction and background recognition. When compared with the cross sections of weak interactions the probabilities of many higher order electromagnetic and "forbidden" strong interactions and decays become significant. Such processes creating background at the search for predicted particles are studied within the project activities. These measurements will test and support the Monte Carlo simulations of the background. Also contribution to the methodologies of low-level counting (radio purity of materials, electronic background reduction, detector calibration, counting statistics) and their application is expected.
