Safety assessments and environmental impact statements for facilities require an estimation of airborne releases. Aerosols generated by accidents are being investigated to develop the source terms for these releases. A severe accidental release event could be a pressurized powder release. Pressurized powder release experiments performed in static air measured the mass airborne and particle size distribution of these aerosols as a function of source size and containment pressure. Both containment pressure and source size were significant in pressurized powder releases. Release in static air can be estimated using the relationships developed in this work. Weight percent of the source powder airborne ranged from approximately 2 to 24%. Mass median aerodynamic equivalent diameters of the airborne particles ranged from 5 to 19 microns. All of the pressurized releases produced a significant fraction of respirable particles 10 microns AED and less.
设施的安全评估和环境影响声明需要对空气传播释放量进行估算。目前正在对事故产生的气溶胶进行调查，以确定这些释放的源项。严重的意外释放事件可能是加压粉末释放。在静止空气中进行的加压粉末释放实验测量了这些气溶胶的空气传播质量和粒径分布，作为源尺寸和 containment 压力的函数。在加压粉末释放中，containment 压力和源尺寸都很重要。可以使用本研究中建立的关系来估算静止空气中的释放量。源粉末的空气传播重量百分比约为2%至24%。空气中颗粒的质量中位空气动力学等效直径范围为5至19微米。所有的加压释放都产生了很大一部分空气动力学等效直径为10微米及以下的可吸入颗粒。 （注：文中“containment”未明确中文释义，保留英文）
