Series Description: This report contains the results of a radiological investigation at ORNL pits 2, 3, and 4 between January and May 1989. The investigation was designed to determine the nature and extent of radiological contamination and then to recommend corrective measures to prevent human exposure and contaminant transport. The report includes a site history for each of the pits; survey scope and methods used for the gamma and beta-gamma activities; results, which indicate the sample identification, location, depth, and activity levels; corrective action recommendations (contaminant isolation, removal); a list of pertinent references; and diagrams of the pit areas showing sample locations. Cesium results are recorded in picocuries or becquerels per gram (pCi/g or Bq/g) while gamma exposure rates are in microrems per hour (ur/hr).
