Aerial radiological survey of the US Department of Energy's Hanford site, Richland, Washington. Date of survey: May/June 1978
During the period from 1 May to 8 June 1978, a radiological survey was conducted over the Department of Energy's Hanford site. A previous survey of the site was performed in 1973. Both surveys were performed by the Energy Measurements Group of EG and G for DOE as part of a nationwide radiation monitoring program. The survey flights were flown at altitudes of 45 m or 60 m, depending on the area, by a helicopter containing 20 sodium iodide detectors. Analysis of the data indicated the predominant radioisotopes at the Hanford site were a mixture of /sup 60/Co, /sup 137/Cs, and naturally occurring radionuclides. The gross gamma activity, along with /sup 137/Cs and/or /sup 60/Co, is presented as isopleth photo overlays of equivalent exposure rate at 1 m above ground level.
