In a radiological event, the lack of preliminary information about the site of explosion and the difficulty in predicting the accurate path and distribution of radioactive plumes makes it difficult to predict expected health effects of exposed individuals. So far, in such a health evaluation, radiation-induced stochastic health effects such as cancer are not included. The Pasquill-Gifford atmospheric classes generally allow connecting atmospheric stability with dispersion of radioactive contaminants to the environment. In this work, an environmental release of radioactive Cs-137 was simulated and the resulting relative risk for solid cancer incidence among the affected population calculated. The HotSpot health physics code was used to simulate the radioactive atmospheric dispersion and calculate the Total Effective Dose Equivalent (TEDE), which was then used to estimate the relative risk of cancer incidence. The main results from this work suggest that the relative cancer risk and atmospheric stability classes are linked by differences in the TEDE. Such a finding may support triage, because it adds additional information on the potentially affected population at the early stages of an emergency response.

在放射事件中，实体癌的风险取决于Pasquill-Gifford大气稳定性等级。

在放射事件中，由于缺乏有关爆炸地点的初步信息以及难以预测放射性烟羽的精确路径和分布，因此很难预测暴露个体的预期健康影响。迄今为止，在这种健康评估中，不包括辐射引起的随机健康影响，例如癌症。帕斯奎尔-吉福德（Pasquill-Gifford）大气类别通常允许将大气稳定性与放射性污染物的扩散连接到环境中。在这项工作中，模拟了放射性Cs-137在环境中的释放，并计算了受影响人群中固体癌症发生率的相对风险。HotSpot健康物理代码用于模拟放射性大气扩散并计算总有效剂量当量（TEDE），然后用于估计癌症发病率的相对风险。这项工作的主要结果表明，相对的癌症风险和大气稳定性等级与TEDE的差异有关。这样的发现可能支持分类，因为它在紧急响应的早期阶段添加了有关潜在受影响人群的更多信息。
