Matrix of radiation exposure as a tool for ranking accidents at radiation-dangerous facilities

In this work the proposed version of the classification of nuclear and radiation risks of emergency situations for objects of use of an atomic energy in the form of a matrix, which is based on the requirements of the international and national regulatory documents. After application of the matrix data about the risks of possible emergency situations on the object in question can be judged on its level of security. Characterizing the object safety settings can be obtained on the basis of the analysis of statistical data or assessments of the expert group.
