| description | A radiological dispersion device is a weapon that combines radioactive
material with conventional explosives for spreading radioactive material
across an inhabited area. This study is focused on evaluating key
parameters in an radiological dispersion device scenario. The calculations
were performed to include two different situations: by using explosives and
by simple mechanical release. Simulations were conducted with the use of the
HotSpot Health Physics Codes. The results suggest the existence of
significant correlations between stability classes in scenarios where they
evolve with time, producing alternations between them. As long as the
stability class remains constant, this latter finding offers the possibility
of creating a suitable response, based on temporal evolutions. Therefore,
the purpose of this study is to: estimate the size of the potentially
affected population, estimate absorbed doses, and estimate the
cost-effectiveness in order to help initial responses by providing
time-sensitive information about the event. A methodology capable of
providing useful information allows prompt decisions and initial
assessments of future risks to be made efficiently. This approach can also
provide a training environment for the personnel responsible for the
decision-making at an early stage of the response. |
