520 _aThe main objective of this thesis is to do environmental nuclear studies of natural radioactivity and exhalation rate of radon at Shuk-Elthoban area in Helwan, Egypt. The present investigation is focused on the study of marble and granite commercially used in many industries using HPGe gamma-ray spectrometer. It has the highest concentration of marble and granite factories in Helwan reaching around 400 factories, constituting 60% to 70% of marble and granite factories in Egypt
