Based on scientific interests and requirements from the legislative framework (food safety control, environmental monitoring, nuclear safety, etc.), the objectives of this project are:

• to conduct a comprehensive analysis of long-lived alpha, beta and gamma emitters both natural and artificial in children foods available on the market and to determine the ingestion dose for certain age groups of children
• development of system (active and passive) for reduction of background radiation in gamma-spectrometric measurements with a view to reduce detection limits especially in the low-energy part of the spectrum in order to facilitate easier, swifter and more accurate determination of isotopes in the uranium and thorium decay series
• development of a mathematical calibration model for germanium detectors for specific samples
• development of novel radiochemical methods of separation of natural and artificial radionuclides from complex samples (food and drinking water) with a view to simplification and acceleration in relation to the existing methods, with emphasis on the development of a automatic method of simultaneous isolation and separation of ⁹⁰Sr, ²¹⁰Pb, ²¹⁰Po and ^226,228Ra from complex samples
