Abstract:Summary The radon and thoron content in atmospheric air at Giza was determined through the period from January (1958 to July 1959) by using the emanometrical technique. The concentration of radon and its decay products was equal to (88±4) 10–18 Curie/c.c. and that of thoron and its decay products was equal to (51±11) 10–18 Curie/c.c.
