The activation mode of a dirty-bomb can modify the health risk estimation profile.

Abstract

Purpose: This study focuses on analytical computer simulations performed to investigate a hypothetical event where the activation of a radiological dispersion device (RDD) triggers a crisis.

Materials and methods: The methodology presents steps centered on the initial evaluation phase of the event (initial 100 hours), aiming to evaluate the radiological risks regarding the development of leukemia. Local environmental changes, sex, and age were also used to assess risks.

Results: It was also estimated that the sex of potentially affected individuals was irrelevant to decisions at the early phase of the event. In contrast, age and the moment of release (day or night) were the most important variables influencing individual radiological risk.

Conclusions: Based on the calculated results, it was possible to conclude that the proposed methodology would significantly contribute to planning the allocation of human resources, reducing future risks.
