title: [Radionuclide indication of the relative economic ecological safety of local ecosystems].
abstract: The use of radioactive isotopes as indicators has been theoretically and experimentally substantiated for comparison of the ecological safety of local ecosystems. The higher concentration of cosmogeneous 7Be and the lower concentration of terrestrial 222Rn and its disintegration products in the environment are, the safer the total ecological situation is in the local ecosystem. Experimental and comparative data on the concentrations of 7Be in the surface air and grass in Moscow are given by the years and months of the early 21st century. The results are assessed as a promising line of the development of radioecology.
