Investigations of Natural Environmental Radiation

Measurement of Background Radiation for Epidemiologic Studies

“…Contrary to other studies, a recent survey by Solon, et al, in the New York metropolitan area, demonstrated that the radiation level inside houses in this area, essentially irrespective of construction material, was not very different from, although generally somewhat lower than, the outdoor level in the same location. 6 The net effect on the total human exposure dose rate will depend on the composition of the structural elements and a time factor to allow for the duration of exposure to indoor and outdoor radiation.…”
