GEOLOGY AND RADIOACTIVITY OF ALKALINE GRANITES OF SOUTHWEST GABAL NUSAB EL BALGOUM AREA, SOUTH WESTERN DESERT, EGYPT

Radioactivity of surface soils from Oyo state, South Western Nigeria

Background: The activity concentrations of some radionuclides in soil samples collected from 20 locations in 8 major towns in Oyo State, Southwestern Nigeria have been determined by gamma-ray spectrometry technique. Materials and Methods: The activity concentrations were determined using high-purity germanium (HPGe) detector (Canberra Industries Inc.). The outdoor absorbed dose rates in air at ...

Geology of the Amber - El Amino Area , Ecstall Metamorphic Belt ,

The Amber El Amino area is located 75 kilometres southeast of Prince Rupert. Access to the area is by helicopter from Prince Rupert or Terrace (Figure 1). The El Amino showing (BC MINFILE 103H 071) is located on Sulphide Creek (Figure 2) which drains eastward into Hanna (El Amino) Creek. The Amber showing (BC MINFILE 103H 171) is located 700 metres north of the El Amino showing. Hanna Creek dra...

emplacement of granites in a transitional regime from volcanic arcs to post-collisional: an evidence from the gabal el-zeit block, gulf of suez region, egypt

gabal el-zeit block at the western coast of the gulf of suez region in egypt consists of two varieties of precambrian granites, namely monzogranite and a peripheral zone of alkali granite. both granitic varieties display moderate (60.1-68.5 wt%) and high silica (73.36-76.16 wt%) contents with high na2o+k2o (7.21-8.61 wt%), respectively. the investigated monzogranite is calc-alkaline metaluminou...

Levels of natural radioactivity in environment in residential area of Moradabad District, Western Uttar Pradesh

Indoor radon and thoron have been measured in the houses ofMoradabad District, Uttar Pradesh India, by means of solid state nuclear trackdetectors. Radon, an invisible radioactive gas, occurs naturally in indooratmospheres and along with thoron is the most important contribution of humanexposure to natural sources. Radon exists in soil gas building materials and indooratmosphere to name but a f...
