[en] The results of a radiological survey of the Shpack Landfill, Norton, Massachusetts, are given in this report. The survey was conducted over approximately eight acres which had received radioactive wastes from 1946 to 1965. The survey included measurement of the following: external gamma radiation at the surface and at 1 m (3 ft) above the surface throughout the site; beta-gamma exposure rates at 1 cm (0.4 in.) from the surface throughout the site; concentrations of ²²⁶Ra, ²³⁸U, and ²³⁵U in surface and subsurface soil on the site; and concentrations of ²²⁶Ra, ²³⁸U, ²³⁵U, ²³⁰Th, and ²¹⁰Pb in groundwater on the site and in surface water on and near the site. Results indicate that the radioactive contamination is confined to the site and to the swamp immediately adjacent to the site
