Optimization of measurement counting time in Gamma-ray spectrometry of soil samples

Measurement of Radioactivity Levels and Health Risks in the Surrounding Soil of Shazand Refinery Complex in Arak, Iran, Using Gamma-Ray Spectrometry Method

ntroduction: The purpose of this study was to measure the radioactivity in the agricultural soil of south-east of Shazand Refinery Complex to determine both reliable baseline data on the radiation level and the radiation dose exposure to the farmers and inhabitants of the studied area. Material and Methods: This study was conducted on 21 soil...

Measurement 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...

Measurement of radium micro-precipitates using alpha spectrometry and total alpha counting methods

Background: This study consists of two parts. The first part deals with both qualitative and quantitative analysis of 226Ra using alpha spectrometry measurement method. In the second part, the percentage of radioactive equilibrium between 226 Ra and its daughter products were determined by alpha spectrometry and total alpha measurement system after elapsed time of 15 days from precipitation. Ma...

Optical simulation and experimental measurement of gamma ray energy spectrum of plastic scintillators with different sizes

The application of large plastic scintillators is widely increasing in the different areas of industry, medicine and security due to technical and economic advantages. One of the main disadvantages of these detectors is the unknown position of Compton edge at gamma ray spectrum. In this research, GEANT4/GATE code has been used to simulate the gamma ray spectrum for different volumes of large pl...

Measuring γ–ray dose of terrestrial samples using β-γ Spectrometry

Background: The existence of some radionuclides in soil and some building materials produce a β-γ radiation field, which in some regions the exposure of these radionuclides to human is high. Materials and Methods: The air-absorbed dose, indoor and outdoor annual effective dose of soil and some building material samples (ceramic, granite, gypsum, etc.). The samples were collected from 3...
