Evaluation of the secondary radiation impact on personnel during the dismantling of contaminated nuclear equipment

The article contains a numerical analysis of the secondary radiation contribution to the total radiation affecting the operational personnel during the dismantling activities of the contaminated equipment at a nuclear power plant. This study considers a widely applicable Monte Carlo particle tra...
