Abstract

Objective: to estimate the hazard of radiation safety to the population and the environment in the Republic of Belarus analyzing the information about discovered orphan sources of ionizing radiation over 2003-2015. Material and methods. The work describes the method of cluster analysis, which made it possible to systematize and analyze the operative information of the Ministry for Emergency Situations of the Republic of Belarus about orphan sources of ionizing radiation in the territory of the country.
