Data on the particulate contamination of the atmosphere at the Oak Ridge National Laboratory were related to laboratory processes and reactor operations for the period from March 1949 to June 1954. A significant correlation existed between one of the chemical separations processes, RaLa, and peaks of particulate activity on the Laboratory area. The RaLa process was monitored during two complete cycles of operation. It was concluded that the major portion of the contaminated RaLa effluent released to the 3039 stack did not fall out or diffuse in the immediate environment, and the stack was not the main means by which RaLa contributes to atmospheric contamination. A serious offender was found to be an underground liquid waste storage tank, W-9, in the south tank farm. This tank is used to store RaLa waste and is vented to the atmosphere. The information obtained from a study done during the one RaLa run indicated that the installation of the fiber glass filter in W-9 tank vent was effective in reducing air contamination from this source. A similar study would possibly be done in a future run to confirm their results. There are appendixes, autoradiogram photos, figures, and tables included in this report.
