Optimization of measurement counting time in Gamma-ray spectrometry of soil samples
The method of optimal measurement counting time in Gamma spectrometry for soil samples was studied. Gamma spectrometry was done based on minimum detectable activity using the HPGe- p type with efficiency of 30% and FWHM 1.7keV (for 1.33 MeV 60Co). The samples were IAEA-RG Th-1, IAEA-RGU-1 and IAEA-RGK-1 prepared in bottles. The measurements were done for 12 different counting times from 5 min t...
متن کاملMonte Carlo Simulation for Airborne Gamma Ray Spectrometry
The aerial measuring terrestrial gamma radiation from airborne platforms is a useful method for characterizing the radiation levels over large areas. Because of the advantage of Monte Carlo method, it is very suitable for simulation of gamma ray transport and interaction with media (soil, air, aircraft and detector), which offer alternative means of estimating detector response and calibration ...
متن کاملMeasurement of Natural Radioactivity in Brick samples of Namakkal, Tamilnadu, India using Gamma-ray Spectrometry
In India, bricks as building materials are mainly prepared by clay using the deposited sediments of rivers, and the radionuclide contents in bricks and brick-making clays should vary with origin and geological condition. Primordial radionuclides in building materials are one of the sources of radiation hazard in dwellings made of these materials. It is important to measure the natural radioacti...
متن کاملDetermination of Primordial Radionuclides in Natural Samples Using HPGe Gamma-Ray Spectrometry
Distributions of primordial radionuclides in soil and vegetables were investigated using high-purity germanium gamma-ray spectrometry. Gamma-ray spectrometry is one of the most accepted and widely used techniques for the detection and analysis of radioactive materials for a wide range of activity. Important properties of the employed gamma-ray detector were also determined to ensure the accurac...
متن کاملMultichannel processing for airborne gamma-ray spectrometry
The conventional approach to the processing of airborne gamma-ray spectrometric data is to first sum the observed spectra over three relatively broad energy windows. These three window count rates are then processed to obtain estimates of the potassium (K), uranium (U), and thorium (Th) elemental abundances. However, multichannel spectra contain additional information on the concentrations of K...
