Measurement of Natural Radioactivity in some Marble Samples used as Building Materials


A comprehensive and short term method has been employed to determine the radioactive contamination from natural sources. So, the natural gamma ray spectrum analysis technique using HPGe have been used to measure the emitted gamma lines from the radioactive isotopes. The specific activity of 238U, 232Th series as well as 40K was determined in the studied samples, which are consisted of eleven types of marble used as building material.
