Abstract
Thorium, uranium, and potassium concentrations have been measured in 1,051 samples from three cores with a total length of 2,700 feet in the Conway Granite of New Hampshire. Thorium and potassium concentrations are generally uniform and probably represent a primary distribution developed during crystallization of the batholith. Uranium, however, is clearly less abundant in surface and near-surface rocks than at depth and has presumably been leached during weathering. These results cast some doubt on the use of outcrop samples for the determination of total radioactivity of large volumes of rock.
