We conduct measurements of gamma radioisotopes (e.g., ⁴⁰K, ²³⁸U, ²³⁵U, ²²⁸Th, ²²⁶Ra, ²¹⁰Pb, ²¹⁰Cs) and alpha radioisotopes (²¹⁰Po, ²³⁸Pu, ²³⁹+²⁴⁰Pu) in various components of the natural environment (soils, bottom sediments, plants, waters) and other materials (e.g., coffee, tobacco products, construction materials, and industrial materials and waste).
