Measurement of The Specific Activity For Beryllium-7 Isotope in Soil of Baghdad City Using Gamma Ray Spectrometry

  This study deals with the measurement of the specific activity radiation for beryllium -7 isotope in Baghdad city for samples of surface soils, by using gamma ray spectrometer technique.       Twenty one samples were collected from surface soil of Baghdad city from Risafa and Karkh sides, (7) samples from  Risafa side and(14) samples from Karkh side, where the axis for locations which are fixed by using (G.P.S.) .  Gamma-ray spectrometry system (DSA 2000) with high purity germanium detector was used, which has (50%) efficiency and resolution of (2.2 keV) at gamma line (1332 keV) of 60Co source.        The specific activity values for beryllium -7  isotope in surface soil of  Risafa and Karkh sides,  ranged between (B.D.L.- 32.827  6.636) Bq/kg for Risafa soil , and (B.D.L.-23.660  3.703) Bq/kg  for Karkh soil. While the average of  beryllium -7  isotope in surface soil of  Baghdad city from Risafa and Karkh sides  would be (32.827±6.636) Bq/kg & (23.660±3.703) respectively.        The results showed that the most samples have a specific activity for beryllium -7  isotope which is higher than that for normal limits of international levels because of falls of atmosphere dust resulting from sun reactions.

The accuracy of ridge mapping procedure in determining the alveolar ridge width

Background: Post-extraction alveolar ridge resorption is unavoidable phenomenon ending with insufficient ridge width. Measuring the physical dimensions of the available bone before implant surgery is an important aspect of diagnosis and treatment planning. Bone height can be calculated from radiographs, while bucco-lingual ridge width can be measured by conventional tomography, CT scanning and ridge mapping.

Radiographic techniques have certain disadvantages. Therefore the ridge mapping technique was used as an option for determining alveolar ridge width.

The purpose of this study was to compare the validity of alveolar ridge width measurements obtained with ridge mapping technique before surgical flap reflection against
