Series Description: This 1948 report discusses the early air monitoring of the X-10 area that led to the discovery of an airborne radioactive-particulate (iodine-131) problem. It outlines the early methods used to monitor and remove radioactive particles and the development and installation of filter and exhaust systems. The report provides information on modifications of slug dissolution facilities, such as those in Building 706-C for isotope production and Building 706-D for RaLa production, which eliminated the formation and distribution of radioactive particles from reactor exhaust stacks. It also discusses experimental work on decontamination by wetting and oiling the roads. The report's appendix provides a bibliography of important reports and memoranda on the particle problem.
