Alpha 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 Indian vegetation samples
Background: Vegetation (food stuff) is grown in soil that contains many radioactive elements such as 238U (uranium), 232Th (thorium) and 40K (potassium), which may get deposited either due to radioactive fallout or/and by absorption from the soil and can pose serious health hazards. Materials and Methods: Natural radioactivity, radiological hazards and annual effective dose assessment was carri...

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...
متن کاملRadioactivity in some sachet drinking water samples produced in Nigeria
Background: Activity concentrations of 40K, 226Ra and 228Ra were measured in some sachet drinking water samples produced in Nigeria. Materials and Methods: The measurement was done by using high-purity germanium (HPGe) detector (Canberra Industries Inc.). The measured activity concentrations for 226Ra (U-series) and 228Ra (Thseries) were used with their ingested dose conversion factors ...
