摘要

在公共场所通过常规爆炸消除可疑物体似乎是安全部队经常考虑的一种选择。放射性分散装置(RDD)使用放射性物质与一定数量的常规炸药相结合,以污染一个区域。极端组织可能会利用这一协议,将放射性物质放在公共场所引起怀疑,从而导致爆炸中和,进而造成RDD事件。本工作旨在通过计算模拟的方法讨论这种协议在放射性威胁中的影响。评估了总最大有效剂量当量(TEDE Max)、Pasquill-Gifford大气稳定性等级(PG等级)和潜在受影响的种群规模。结果考虑了两种放射性核素Cs-137和Sr-90。研究结果允许我们推断TEDE Max和表面污染强烈依赖于PG类。此外,受影响的种群大小取决于羽流大小,这似乎与放射性核素无关,但与PG类无关。因此,PG类在放射性威胁中起着关键作用。在面对事件时,这些发现可能对支持决策有价值。

Radiological urban threat due to special protective actions from security forces
The neutralization of suspicious objects by a conventional explosion in public places seems to be an option often considered by security forces. A radiological dispersive device (RDD) uses a radioactive material coupled to an amount of conventional explosive in order to contaminate an area. Extremist groups may take advantage of such protocol by leaving the radioactive material in public places to provoke suspicion, thus leading to the neutralization by an explosion, which in turn creates a RDD event. This work aims to discuss the influence of such a protocol in the radiological threat by means of computational simulation. The total maximum effective dose equivalent (TEDE Max), the Pasquill–Gifford atmospheric stability classes (PG classes), and the potentially affected population size were evaluated. The results consider two radionuclides Cs-137 and Sr-90. The findings allow us to infer that TEDE Max and surface contamination are strongly dependent on the PG classes. In addition, the affected population size depends on the plume size, which seems to be independent of the radionuclide, but not of the PG classes. Therefore, PG classes play a key role in the radiological threat. The findings may be of value to support decisions when facing an event.
