Radiological risk associated with a fire scenario in a radioactive waste deposit

A fire at the disposal of radioactive waste can result in significant damage, as well as serious risks to the environment and the health of the general public. The norms of CNEN (Comissão Nacional de Energia Nuclear), CNEN 2.03; CNEN 2.04 and CNEN 8.02 include fire protection regulations and have criteria and requirements that aim to prevent the occurrence, neutralize the action and minimize the effects of the fire on the radioactive and/or toxic mate-rial present in the installations. For decision making due to a fire scenario containing radioactive material, it is fundamental to have information that can allow the estimate of the dose to which the population will be submitted. This work proposes to identify the radiological risk of cancer in the respiratory system using the BEIR V model, associated with a fire scenario containing radioactive material generated in the Hotspot code.
