Abstract

The PHARE Project “Supervision for closing of the Uranium Mines at Eleshnitza and Dospat” foreseen recultivation of tailing pond at hydrometallurgical plant “Zvezda”Eleshnitza, construction of Waste water treatment plant for drainage waters, and construction of depo for domestic wastes in quarry to mine “Dospat” – Barutin. The radiation protection during the rehabilitation engineering works is carry out in accordance with Inception Report present by Supervisor; the actual standard document; the permission of Agency for Nuclear Regulation for working with open radioactive matters, which content natural radionuclides; the geographical and demographical characteristics of the regions. In presented report are discussed the data from measurements at place, laboratory analyzes of samples from working areas and estimation of the foreseen and real levels of expose of radiation to personnel during the April 2002 – December 2003. It is shown the approach for valuation of radiation situation, the controlling parameters, the places of samples taking and the number of measurements, as well as the data from the direct and indirect defining of equivalent doses of some category personnel of the Contractor. The results from radiation control in working environment are generalized in table form, showed at maps (according to data by GPS system for point connection), and the results are illustrated with documental pictures/photos, which investigated the real situation of the working areas during the different stages of project realization. We draw a conclusion that the project realization decides one very important ecological problem as in the same time we do not expect increased professional risk for the personnel/staff on the site.
