Abstract: In this study, we carried out Particle Induced X-ray Emission (PIXE) analysis of tap water from several houses located in different parts of Borojerd city In Iran. A 2.0 MeV proton beam was employed to excite the samples. The concentration of these elements varied from one month to other depending on session but the average elemental concentrations during a complete year seams invariant. The main objective of this work was to characterize and to monitor the trace elements in drinking water, as well as to provide valuable information about the levels of heavy metallic pollutions. The experimental results of trace elements analysis of drinking water of city of Borujerd which was sampled in different months during a year, has been presented by a spectrum of X-rays (in mg/lit) and graphs of quality concentration of elements. Our results were within the permissible limits reported by International standards, and WHO guidelines for drinking water quality and could be observed that the drinking water of Borojerd lacks any toxic trace elements and heavy metals.

Abstract: The radioactivity of fifteen cars oil samples were be studied in this research, eight of them are local collected from the fuel station in Baghdad, the remaining seven are imported from different origins collected from local markets of Baghdad. The specific activity of the detected radionuclides were be measured by the spectral analysis technique of gamma-ray using high purity germanium (HPGe) detector. It was also a calculation of radiation risk factors; and the specific effective activity (Aeff), which was calculated for the first time in this research. Eight radionuclides were be detected in this work, 226Ra, 214Pb and 214Bi which belong to the uranium-238 series and 212Pb, 208Tl and 228Ac which belong to Th-232 series in addition to 40K and 137Cs. The results shown that the radium equivalent activity (Raeq) were 1.73 -13.72 Bq/l, the absorbed gamma dose rate (Dˠ) were 0.82 -6.24 nG/h, the representative gamma index (Iγr) were 0.012-0.096, the indoor annual effective dose equivalent (AEDE) in were 0.004 - 0.03m Sv/y, the outdoor annual effective dose equivalent (AEDE) out were 0.002-0.037 mSv/y, and the internal hazard index (Hint) 0.009-0.052, the external hazard index (Hext) 00.5-0.037. Another factor has been calculated for the first time in this research it’s the specific effective activity (Aeff) which is ranged between 1.76 and 13.26 Bq/l. The obtained results were compared with the worldwide average; it was within the recommended values. That mean, oils used in automobile engines are safe, valid for consumption and does not pose a danger to society and the environment.

Abstract: In this study, forty samples of different types of raw sands, magnetite, green silicate and processed mixture of ilmenite, magnetite and green silicates have been mineralogical and radiometrically investigated after preparation. Determination of the mineral contents, radioactivity levels and their corresponding environmental impacts was also carried out. The radioactivity: 238U, 232Th, 226Ra and 40K, of these samples are of naturally occurring origin. The EDX analysis was applied for identification of trace elements in the samples. The microscopic investigations of the samples indicate that the black sand samples are economically rich in heavy minerals such as ilmenite, magnetite, zircon, rutile and monazite; in addition to leucoxene. While the processed and unprocessed green silicate contain ilmenite, zircon, sphene, monazite and calamine with quartz and other silicate minerals. The highest values of activity concentrations of 238U, 232Th, 226Ra and 40K were observed in black sand, processed and unprocessed green silicates samples. These high radioactivities are attributed to the presence of zircon, monazite and sphene. The radiological hazard parameters; the absorbed dose rate (D), annual effective dose equivalent AEDE, radium equivalent activity Raeq, external hazard index Hex, internal hazard index Hin and gamma activity concentration index Iγ of the studied samples were estimated. The results obtained were tabulated, evaluated, interpreted and discussed.

Abstract: Due to constant exposure of Human beings to radiation caused by terrestrial, extra-terrestrial and anthropogenic radio nuclides, it is necessary to determine/estimate the activity of various radio nuclides in environmental media such as vegetation, soil, and water. In the present research, the activities of 226Ra, 232Th and 40K are measured in soil, vegetation and water samples, collected from Talagang Tehsil-District Chakwal of Pakistan using a HPGe based gamma spectrometry system. The measured mean activity of 226Ra, 232Th and 40K in soil samples was found to be 31.19±1.2, 47.00±2.30 and 589.31±17.52 Bqkg-1, respectively. The measured mean activity of these radionuclides in all water samples was found to be below minimum detectable activity. The measured mean activity of 226Ra, 232Th and 40K in vegetation samples was 19.92±3.09, 25.36±8.11 and 4982.94±85.68 Bqkg-1, respectively. No anthropogenic 137Cs was detected in these environmental samples. Mean radium equivalent activity (Raeq), external radiation hazard index (Hex), internal radiation hazard index (Hin) and absorbed dose rate (D) for the area under study were determined as 142.92 Bqkg-1, 0.38, 0.47 and 66.47 nGyh-1, respectively. The annual effective dose equivalent (AEDE) varied in the range from 0.03 to 0.12 mSv y-1. It is concluded that the surveyed area do not pose any significant radiological risk to the population and environment.
