Results of long-term monitoring of environment radioactivity on the site of JINR

The purpose of the present work is to present the objective information on the level of radioactivity in the environment on the site of the Joint Institute for Nuclear Research (JINR), based on the results of long-term measurements carried out at a specialized laboratory of radiation control at JINR. In the work, results of measurements for 1986-2002 are presented: the total beta- and gamma-radioactivity of the grass and soil, the concentration of some radionuclides in the grass and soil, specific alpha- and beta-radioactivities of water reservoirs near Dubna, total alpha- and beta-radioactivities of snow, the photon and the charged particles radiation background on the territory of Dubna
