Radioactivity: Detection and Measurement

HPGe and Scintillation Detectors Comparisons on Waste Drums Radioactivity Measurement

Two measurement systems, one being comprised of three HPGe detectors and the other being a 4π measurement system of the assembly of 10 sets of scintillation detectors, were compared for their measurement performance in operations of radioactive waste drum radioactivity measurement and clearance and release operation of decommissioning. The system features of the former were high costs, capable ...

Radioactivity level and the measurement of soil gas radon concentration in Dikili geothermal area, Turkey

Background: The natural radioactivity level and the radon concentration of soil were measured at four important geothermal area located in Dikili geothermal region, Turkey. Materials and Methods: The natural radionuclide content of soil samples were measured by NaI(Tl) gamma spectrometer system and the soil radon concentration were determined using Kodak-Pethe LR-115 Type II Solid State Nuclear...

Measurement of Environmental Radioactivity with Basic Counting Equipment

Measurement of Intrinsic Radioactivity in a GSO Crystal

Scintillating crystal detectors offer potential advantages in low-energy low-background experiments for particle physics and astrophysics. The GSO crystal is an interesting detector to explore for future neutrino physics experiments. The contributions to background due to the various channels of intrinsic radio-isotopes from the 232 Th and 238 U series are identified and studied with time-corre...

Measurement of Natural Radioactivity in Certain Types of Nut Samples in Iraq

Introduction: The present study was conducted to measure the specific activities of 226Ra,232Th and 40K, in some samples of nuts collected from the local markets in Iraq. In addition, this study sought to calculate the annual effective dose of gamma ray to children and adults. Material and Methods: The quantification of radionuclides was accomplished by gamma spectrometry NaI (Tl) detector. Res...
