The Colorado Department of Public Health and Environment sponsored a study to reconstruct contaminant doses to the public from the Rocky Flats nuclear weapons plant. This analysis of the September 1957 fire in a plutonium fabrication building that breached the building air filtration system is part of the Colorado Department of Public Health and Environment study. The plutonium release from this fire is estimated using environmental data collected around the time of the fire and an air dispersion model. The approximate upper bound on the total plutonium release from the fire is 1.9 GBq (0.05 Ci), with an uncertainty of about two orders of magnitude. Off-site air concentrations and deposition of plutonium resulting from the approximate upper-bound release are estimated. The highest predicted off-site effective dose resulting from the approximate upper-bound release is about 13 microSv (1.3 mrem).
科罗拉多州公共卫生与环境部发起了一项研究，旨在重建洛基弗拉茨核武器工厂对公众造成的污染物剂量。对1957年9月钚制造大楼火灾的分析是该研究的一部分，此次火灾破坏了大楼的空气过滤系统。利用火灾发生时收集的环境数据和空气扩散模型估算了此次火灾中钚的释放量。火灾中钚的总释放量的近似上限为1.9吉贝可（0.05居里），不确定性约为两个数量级。估算了近似上限释放量导致的场外空气中钚的浓度和沉降。近似上限释放量导致的最高预测场外有效剂量约为13微希沃特（1.3毫雷姆）。
