Series Description: This 1963 report describes the equipment, sampling procedures, and analytical procedures employed to determine the efficiency and error rates for charcoal filters used to restrict off-gases containing iodine. It describes the construction of the charcoal cartridges and concludes that cartridge efficiency must be taken into account when estimating stack discharges. The report includes a "plot of Iodine-131 Distribution in Charcoal Cartridges" and a table of charcoal cartridge iodine collection efficiencies which list the percentage of iodine-131 removed from off-gases.
