the present paper measures natural radioactivity in different areas of wassit governorate, using (hpge) detector. gamma spectrum analysis for each sample along with caululated specific activity show that the average concentrations of u-238, th-232, and k-40 have been 19.420±4.7 bq/kg, 18.487±5.05 bq/kg, and 204.266±46.9 bq/kg respectively, which is lower than the worldwide average value. while ...

Background: Health hazards associated with exposure due to the natural radioactivity which is a part of our physical environment are of great concern. In order to assess the risks associated with exposure due to the natural radioactivity in soil and building materials, extensive studies have been carried out all over the world. The most commonly encountered radionuclide’s are 238U, 2...

Radioactivity of terrestrial radionuclides Ra, Th and K in phosphate rock samples has been measured using gamma ray spectrometry system with an HPGe detector. The samples showed fairly high mean concentrations, 410±39 Bq.kg of Ra, 7.9±0.95 of Th and 37.6±4 of K. Mean absorbed gamma dose rate of 181.9±20 nGy.h was measured in air. Assessment of radiological hazards was made by calculating radium...

The measurements of Ra, Th and K using gamma spectrometry and radon concentration and exhalation rates measurements using solid state nuclear track (LR-115, Type-II plastic) detectors are used to asses a first order exposure risk for the persons residing in Fatehbad and Hissar districts of Western Haryana, India. The concentration of Radium, Thorium and Potassium in the soil samples varies from...

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...

the radionuclides 226ra, 232th and 40k concentrations measured as well as radiological parameters, for 14 granite samples that use in iran as building material were calculated. the measurements of the radioactivity concentrations were carried out at nuclear physics laboratory university of tabriz. this subject is important in environmental radiological protection, since granites are extensively...

Background: Measurement of the radiation dose distribution is important in assessing the health risk a population and serve as reference in documenting changes to environmental radioactivity in soil due to man-made activities. Materials and Methods: The activity concentration of 238U, 232Th and 40K in soil samples obtained from different locations in Ajaokuta Local Government area was measured ...

abstract background: the radiological impact of the use of phosphate fertilizers in soil is due to the internal irradiation of the lung by the alpha particles, short lived radon-thoron progeny and the external irradiation of the body by gamma rays emitted from radionuclides in situ. this paper describes the results of gamma spectrometric measurements of the concentration of the natural radionuc...

To assess the environmental radioactivity levels and hence to determine the population exposure in Kutubdia Island, Bangladesh the sediment samples were analyzed by using gamma ray spectrometry. In those sediment samples the average activity concentration of natural radionuclides 238U, 232Th and 40K were found 15.39±1.67, 38.35±0.76 and 475.51±21.15 Bq/kg respectively. ...

Background: Ondo city in Ondo State Nigeria includes Ondo East and West could be described as a research city due to antecedent number of research institutes. Materials and Methods: Dose due to radioactivity content of soil samples from sixteen waste dump sites in Ondo, Southwestern Nigeria was determined using gamma-ray spectrometer in order to evaluate the radiation hazard health profile and ...
