OPERATIONAL CONDITIONS OF STORAGES FOR PRODUCTS OF DECONTAMINATION OF THE TERRITORIES OF BELARUS AFTER THE ACCIDENT AT CHERNOBYL NPP AND EVALUATION OF THEIR RADIOECOLOGICAL STATE

摘要

As a result of carrying out the measures on decontamination of the territory of Belarus after the Chernobyl accident, the storages for radioactive products of decontamination have been arranged in the Republic. Up to now, 69 storage sites for radioactive products of decontamination have been examined and registered. Six of them, the most typical, with the highest activity, are under constant control with the help of the network of the hydrogeological observation holes. The analysis of the field conditions of the storage sites at the territory of Belarus has shown that there is the violation of requirements for safe storage practically for all storages. The evaluation of protection of the ground water against radioactive contamination has shown, that in 10 -100 years, the contamination of the ground water with caesium-137 is possible in concentrations lower than the Republican permissible levels and with strontium in concentrations significantly exceeding the specified values.
