Alpha radioactivity in Indian cement samples
ABSTRACT Background: The essential constituents of cements like lime, silica and alumina are derived from earth’s crust in which radioactive elements like uranium, thorium etc are also present in varying amounts almost everywhere. These two elements are considered as the parent elements of uranium and thorium radioactive decay series in which radon and thoron are produced respectively as decay...
متن کاملMeasurement of I Radioactivity in Groundwater of Radioactive Waste Disposal Site
The investigation of the environmental radioactivity around the radioactive waste disposal site in Gyeongju is being carried out. The radioactivity of I in groundwater and seaweed are to be measured. The analytical method to measure the radioactivity of I in aqueous media was established. This method contains oxidation-reduction reaction, anion-exchange separation and palladium precipitation. T...
متن کاملRadioactivity 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 ...
متن کاملCement-within-cement revision hip arthroplasty.
We reviewed 19 revision hip arthroplasties in which the new femoral component had been recemented into the old, intact cement mantle. The mean time from the first operation to revision was 64 months and the average follow-up was 59 months. There were 7 excellent, 11 good, and one fair result. No femoral component had been revised for loosening and all the stems appeared radiographically stable....
