WebThe crystals of (Lu,Gd)3(Ga,Al)5O12 multicomponent garnets with high density ρ and effective atomic number Zeff are characterized by high scintillation efficiency and a light yield value up to 50,000 ph/MeV. During recent years, single-crystalline films and composite film/crystal scintillators were developed on the basis of these multicomponent garnets. …
WebThe activity of a source in a pig may be calculated without having to remove the source, given that the dose-rate outside of the pig is measurable. A third useful calculation is shield thickness. Input the current dose-rate and the desired dose-rate and the thickness of the shield required will be calculated for you. WebBeta particles can be stopped by a thin book or about ten or twenty centimeters of air, while gamma rays might require several room lengths of air or several lead bricks to be stopped on average.
