Radioactivity Levels in Some Sediments and Water Samples from Qarun Lake by Low–Level Gamma Spectrometry
The specific activities of the natural radionuclides U, Ra, Th and K were measured in sediments and water samples collected from the Qarun lake (Middle Egypt) in order to gather information about radionuclides mobility and distribution. In the sediment and water in general, the concentration of U was found to be higher than that of the Th and the activities of Th, Ra and U in this lake falls wi...

Determination of natural radioactivity by gamma spectroscopy in Balad soil, Iraq
The specific activity of naturally and man_maderadionuclides in soil was measured in 30 different locations in Balad city, Salahadeen Governorate, Iraq. The mean of these specific activities of Bi,Ac,Kand Cs in soil were found to be 0-5.2234,0-8.7271,101-1216.83,0-1.4320 Bq.kg respectively. The radium equivalent activity was calculated and it was range from 107.788 Bg/kg to 1219.472 Bg/kg. The ...
متن کاملAlpha radioactivity in Indian cement samples
ABSTRACT Background: The essential constituents of cements like lime, silica and alumina are derived from earth’s crust in which radioactive elements like uranium, thorium etc are also present in varying amounts almost everywhere. These two elements are considered as the parent elements of uranium and thorium radioactive decay series in which radon and thoron are produced respectively as decay...
متن کاملNatural radioactivity in rock samples of Aravali hills in India
Background: Natural radionuclides in rock samples, primarily 238U (uranium), 232Th (thorium) and 40K (potassium), are the main source of radiation exposure to workers and general public and their measurement is of paramount importance from radiation protection point of view. Materials and Methods: Gamma spectrometry using HPGe detector was used to measure the radioactivity and assess the radiol...
