Series Description: This record series consists of quarterly monitoring reports of the Applied Health Physics Division 1954-63. Each report provides narrative and quantitative information on radiation monitoring, radiation surveying, dosimetry, and environmental monitoring. The section on radiation monitoring includes subsections on personnel exposure, atmospheric monitoring, water monitoring, background measurements, and ionizing radiation. Monitoring measurements are provided in milliroentgens/hour. Radiation monitoring also provides a list of releases by division and specific work location/building number. Radionuclides detected in personnel include iodine-131 and cesium-137. Whole and partial body counting data are provided in rems/hour. Atmospheric monitoring is measured in millicuries/cubic centimeter and water analyses are reported in millicuries/milliliter. Water analyses include monitoring results of White Oak Creek and Clinch River. Background radiation and ionizing radiation are reported in millirems/hour. Environmental monitoring included milk analyses in picocuries/liter and thyroid analyses of cattle within a 100-mile radius of Oak Ridge. Radionuclides reported as monitored, include cesium-137 and iodine-131.
