This work considers the implications of cloth masks due to the COVID-19 pandemic on suspected plutonium inhalations and dose assessment. In a plutonium inhalation scenario, the greater filtration efficiency for large particles exhibited by cloth masks can reduce early fecal excretion without a corresponding reduction in dose. For plutonium incidents in which cloth masks are worn, urinary excretion should be the preferred method of inferring dose immediately after the inhalation, and fecal excretion should be considered unreliable for up to 10 days.

布COVID面罩对吸入P的尺寸分布,呼吸沉积和粪便生物测定监测的意义。

这项工作考虑了由COVID-19大流行引起的口罩对可疑p吸入和剂量评估的影响。在a吸入的情况下,由布口罩表现出的大颗粒更大的过滤效率可以减少粪便的早期排泄,而不会相应地减少剂量。对于戴有口罩的p事件,最好是通过尿液排泄来推断吸入后的剂量,并且认为粪便排泄在长达10天之内是不可靠的。
