Natural Radioactivity in Ground Water Supplies in Maine and New Hampshire
In April 1958, water samples from more than 45 wells in the Raymond and Windham areas of Maine were analyzed for radioactivity by the U.S. Public Health Service (USPHS) and the Maine State Health Department. The activity of radon and its daughter products was found to be 2,500‐583,000 μμ/l. The long‐life alpha activity‐primarily uranium, thorium, and radium‐was found to be approximately 0‐666 μƁ/l. It may also be noted that a radiologic survey of the geology of this area showed rather high background radiation. A detailed sampling program to define the occurrence and extent of natural radioactivity in groundwater supplies of Maine and New Hampshire was undertaken during the summer of 1959. The program in Maine included radioassay of groundwater supplies in the Raymond, Yarmouth, Rumford, and Lewiston areas. In New Hampshire, samples were collected from areas in and around the towns of Nottingham, Northwood, Deerfield, Crafton, and Franklin. In addition, the activity in the water supply sources and in the system of Dover, N.H., a city of about 20,000 people, was studied in some detail. After considerable experimental work, it was decided to adopt the de‐emanation‐scintillation method for the analysis of radon and radium. The method is similar to that used by Holaday and others for the detection of radon in air within uranium mines. A more comprehensive discussion of the method and techniques used in this study has been reported by Higgins and others in this issue of the Journal.
