  • Studies of radioactive contaminations and heavy metal contents in
           cosmetics
    • Authors: Hayam Ahmed Abdel-Ghany, Fatma Ragab
      Pages: 181 - 197
      Abstract: Measurement of radioactivity in cosmetics such as face powders and eye liner (kohl) has not been reported so far. Herein gamma ray spectrometry and CR-39 solid state nuclear track detector have been used to investigate six cosmetics of different brands. The results have demonstrate that the average values of specific activities of <SUP align="right">238</SUP>U, <SUP align="right">232</SUP>Th and <SUP align="right">40</SUP>K were 12.66±2.96, 14.58±8.83 and 269±120 Bqkg<SUP align="right">−1</SUP>, respectively. Also the average radon exhalation rate was 0.21±0.04 Bqm<SUP align="right">−2</SUP>h<SUP align="right">−1</SUP>. The calculated radium-equivalents were lower than recommended value (370 Bqkg<SUP align="right">−1</SUP>). The absorbed dose rates due to the natural radioactivity of the investigated samples ranged from 6.83±2.6 to 99.5±51 nGyh<SUP align="right">−1</SUP>. Also, X-ray fluorescence spectrometry studies showed that the concentrations of the heavy Mo, Sr, Pb, Zn, Cu, Ni, Fe, Mn, Rb, As, Zr and Cr were 4±0.96, 26.93±12.24, 110135±109973, 672.98±433, 1001±722, 318±145, 3847±790, 60±25, 24.71±13, 9002±4210, 24.71±18 and 153±72 ppm, respectively.

  • Assessment of early and late DNA damages in interventional radiologists
           exposed to protracted low dose and dose rate of X-radiation
    • Authors: Safa Abdul Syed Basheerudeen, Sakina Murtaza, Venkateswarlu Raavi, M. Bhavani, Santhosh Joseph, T.R. Muralidharan, Perumal Venkatachalam
      Pages: 198 - 209
      Abstract: Occupational radiation exposures for interventionalists are considered as the highest received doses among medical practitioners and contributing a risk of DNA damage. A significantly higher γ-H2AX foci and unstable chromosomal aberrations (p > 0.001) was observed in Peripheral Blood Lymphocytes (PBL) of medical professionals when compared to healthy volunteers, whereas translocations did not show any difference. The results suggest that low-dose protracted radiation exposure can induce DNA damages in PBL and can get repaired or misrepaired and develop into chromosomal aberrations.

  • Determinations of soil radioactivity, indoor radon concentration levels
           and their correlation in Oke-Ogun area, Southwestern Nigeria
    • Authors: Augustine Kolapo Ademola, Rachel I. Obed
      Pages: 210 - 221
      Abstract: Indoor radon concentration measurements in 116 rooms and gamma activity measurements in the soil samples around the rooms were carried out in Oke-Ogun area (Southwestern, Nigeria). The mean activity concentrations of <SUP align="right">40</SUP>K, <SUP align="right">232</SUP>Th, and <SUP align="right">238</SUP>U in the soil were 3±5, 25±7 and 212±99 Bqkg<SUP align="right">−1</SUP>, respectively. The mean absorbed dose rate (D) and the effective dose estimated were 44±8 nGy h<SUP align="right">−1</SUP> and 45±8 μSv y<SUP align="right">−1</SUP>, respectively. Radon concentrations in the rooms varied from 148 Bqm<SUP align="right">−3</SUP> to 627 Bqm<SUP align="right">−3</SUP> with mean of 282±99 Bqm<SUP align="right">−3</SUP>. The estimated mean annual effective dose is 7±2 mSv y<SUP align="right">−1</SUP>. It is therefore advisable for the inhabitants of the study area to ventilate their houses regularly, to reduce the possible risk of contracting lung cancer. Radon concentration in the rooms surveyed show a good correlation (R² = 0.702) with <SUP align="right">238</SUP>U/<SUP align="right">226</SUP>Ra activity in soil samples.

  • Radiation and evolution: from Lotka-Volterra equation to balance
           equation
    • Authors: Augustine Kolapo Ademola, Rachel I. Obed
      Pages: 222 - 233
      Abstract: The paper presents the concept of balance equation as a result of jostling process between detrimental and beneficial factors due to ionising radiation impact on the human population. The Lotka-Volterra equation was used to describe the evolution process of the population in low-dose radiation environment. The balance equation, which is a result of Lotka-Volterra's equation stabilisation over time, describes correctly most of the human population, wherein the probability of detrimental (cancerous) processes equals the probability of beneficial (hormetic) processes. It concludes that most of people respond via threshold dose-response curve, while radiosensitive people respond using linear model and radioresistant people respond using hormetic one.

  • Radioactivity concentrations and dose assessment for agricultural soil
           samples around the Jordanian petroleum refinery in Zarqa, Jordan
    • Authors: Feras Afaneh, Mashour Al-Momani, Jamal Al-Jundi, Allayth Aldrabee, Hassan Juwhari
      Pages: 234 - 243
      Abstract: The activity concentrations of the natural radionuclides (<SUP align="right">238</SUP>U, <SUP align="right">232</SUP>Th, <SUP align="right">40</SUP>K) in the agricultural soils around the Jordanian petroleum refinery in Zarqa city, Jordan, were investigated. The soil samples were collected from three different agricultural regions (X, Y and Z). The <SUP align="right">232</SUP>Th activity concentration was found to be too low in all samples. The average activity concentrations in Bq/kg were found to be: 40.1±1.6 for <SUP align="right">238</SUP>U and 372.6±11.9 for <SUP align="right">40</SUP>K in X-site, 38.3±1.9 for <SUP align="right">238</SUP>U and 486.4±15.0 for <SUP align="right">40</SUP>K in Y-site, and 45.4±1.3 for <SUP align="right">238</SUP>U and 313.3±11.1 for <SUP align="right">40</SUP>K in Z-site. Our findings are within the worldwide average values (UNSCEAR, 2000). The absorbed dose rates were calculated and found to be in the range of 20.86-47.62 nGy/h with an overall average value of 34.66 nGy/h. The average outdoor annual effective dose equivalent was estimated to be 41.13 ± 11.64 μSvy<SUP align="right">−1</SUP> which is below the world average of 70 μSvy<SUP align="right">−1</SUP>.

  • Assessment of the possible radiological hazard caused from marble and
           granite tails commercially available in Egypt
    • Authors: Feras Afaneh, Mashour Al-Momani, Jamal Al-Jundi, Allayth Aldrabee, Hassan Juwhari
      Pages: 244 - 254
      Abstract: This paper reports the natural radioactivity and possible radiological hazards in different types of local and imported marble and granite tiles used as covering building materials in Egypt. Gamma-ray spectrometry was used to estimate the <SUP align="right">226</SUP>Ra, <SUP align="right">232</SUP>Th and <SUP align="right">40</SUP>K activity concentrations. The obtained values were found in the ranges 15-73, 29-203, and 50-253 Bq kg<SUP align="right">−1</SUP> in marbles and 23-179, 78-317, 113-1207 Bq kg<SUP align="right">−1</SUP> in granites for <SUP align="right">226</SUP>Ra, <SUP align="right">232</SUP>Th and <SUP align="right">40</SUP>K, respectively. Using indirect methods radon exhalation rates were calculated, the obtained values varied from 2.1 to 9.7 and from 3-23.9 Bq m<SUP align="right">−2</SUP> h<SUP align="right">−1</SUP> for marble and granite samples, respectively. Radon concentrations in the room caused by marble and granite samples were also estimated. Under normal ventilation (0.5 h<SUP align="right">−1</SUP>), the obtained values were below reference level (100 Bq m<SUP align="right">−3</SUP>) recommended by World Health Organization. Most values of external annual dose and annual doses due to the indoor radon exposure (E<SUB align="right">Rn) were within recommended.
