The report discusses the accumulation of data as to the distribution of radioactive particles on the X-10 area. A total of 22 collection frames in service as of 9/23/48 were placed to give close coverage of areas surrounding the 105 Stack and the 706-D Stack as well as off area locations chosen depending on prevailing wind direction, accessibility, and direction from the plant of heavily populated areas. Data tables are prepared. Slug ruptures are also discussed. The data is believed to substantiate to some extent the validity of the theory that "bleeding" of relatively small numbers of particles takes place during and after slug removal operations. Evidence to date seems to also indicate the possiblity of sources of particulate activity other than the 105 Stack or ruptured slugs, probably coming from chemical operations. For example, particulate material from the 105 area shows a relatively long half-life, while those collected from 706-D indicate a more rapid decay. Filters in air conditioners of 104 B located in the attic about 50 feet from the west end of the building were also examined and showed many spots of localized activity.
