“…The specific activities of 226 Ra and 232 Th reported in previous studies [16], [17] and [18] were higher than the values of the present study. The maximum value of 40 K activity in the present study is much lower than those reported in earlier publications [10], [17], [16], [18], [19], [20], [21] and [22]. The high recorded values of the radionuclides in some soil samples are attributed to the geochemical composition and the samples were collected from the areas around the oil wells.…”

Everything around us is continuously exposed to the radiation of the Naturally Occurring (NORM) such as cosmic rays and terrestrial radioactive elements. However but human and technological activities may contribute to increasing the effect causing what is called the Technologically Enhanced Naturally Occurring Radioactive Materials (TENORM) In the present Radioactive Materials investigation, the radioactivity in soil samples from Jabal Bawr oil site of Kirkuk-Iraq have been studied using a high purity germanium (HPGe) detector. The specific activity of 226 Ra, 232 Th, 40 k and 137 Cs varied between 24.4-68 Bq kg -1 , 11.6-27.2 Bq kg -1 , 207.2-591 Bq kg -1 and BDL-2.40 Bq kg -1 respectively. The hazard indices (the radium equivalent activity, the absorbed gamma dose rate, the annual effective dose rate, the external and internal hazards, the Gamma radiation representative level index, and excess lifetime cancer risk have been calculated.The results obtained of some sites were found to be higher than the allowable worldwide values. Statistical analysis has been implemented to explain the obtained results.

“…To nd the Skin dose contamination of the 252 Cf source using SDCC for wide energy regions. In radiation, works have been studied especially in terms of shielding and other purposes besides contamination in literature [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]. Using ICRP107, the 252 Cf radionuclide source is extracted and the results are provided in Table 3.…”

Handling of 252Cf radionuclide source can lead to contamination of the skin surface in case of an accident. There is still an increasing demand to have dose conversion coefficients of each primary particle and different sources. On the other hand, there is no literature that presents actual values and methods for determining skin dose contamination and its coefficients for 252Cf source. Thus, this paper is concerned with quantifying the received dose rate and its coefficients in the skin as a result of a contamination scenario. The equivalent and absorbed dose rates, as well as SDCC, are estimated using MCNPX Monte-Carlo simulation’s well-established calculation code in the skin. Two methods i.e. watt fission and doppler effect are proposed for calculating particles’ spectra, and consequently, with the help of flux–to–dose conversion function Equivalent dose rates are derived. Also, the SDCC on the skin surface for different particles is obtained and these values are reported for 252Cf radionuclide. The particles of interest in this study are neutrons and gamma photons. The new dose coefficients allow the estimation of the skin dose contamination in radionuclides of interest.

HAP (Hydroxyapatite) bio-composite has been used extensively to repair and replace bone and teeth tissues in the human body. However, because of the poor mechanical features of HAP bio-composites, significant enhancements in the strength and toughness of pure HAP have been achieved by the insertion of various alloys and materials into HAP. Accordingly, the present study evaluates the radiation shielding and mechanical features of the Fe2O3 -reinforced HAP composite as an implant for 0.0, 2.5, 5.0, and 7.5 wt.% Fe2O3. Also, the composite response in a magnetic field has been investigated. Employing FLUKA Monte Carlo Code, radiation shielding factors are obtained. In addition, the mechanical characteristics of the studied composites are evaluated using the theoretical method. Findings reveal that increasing the Fe2O3 contents in HAP bio-composite enhances the preferred samples’ radiation shielding and mechanical qualities. Furthermore, in the absence of a magnetic field, the particles' spatial map exhibits symmetric behavior along the x-axis, however, a different trend is observed in the presence of a magnetic field with a value of Bx=5 microT.
