Dose Calculations and Determination of Shielding Characteristics for Protecting Emergency Workers During the Response to Radiological Emergencies

Effective and efficient response to radiation emergency including those with security related events is the main goal of the national strategy for emergency preparedness and response. Accidents due to radioactive sources have a wide range of possibilities and consequences. Mapping of the radiation doses related to the exposure of radioactive sources with different activities give a fast view and expectation of the consequences and the required protective actions and other response actions. The aim of this publication is to provide a practical guidance for emergency response in terms of absorbed dose rate and their related required shielding parameters for different categories of radioactive sources that, if implemented, will provide a fast assessment and response capability needed to protect the public and the workers in the event of different types of radiological emergencies including radioactive sources. MNCP Code is used for predicting the absorbed doses from the famous radioactive sources under different hazard categories (categories 2&3) in case of loss of their shielding at different distances and to calculate their appropriate shielding characteristics.
