Introduction: Nuclear radiation is potentially harmful to humans and soil contamination with radionuclides is the main source of human radiation exposure. These radionuclides can., enter to human body through the food chain. In this study, 34 soil samples were collected from between Arak city and Shazand Power Plant over 20 km length and analyzed. Materials and Methods: The specific activities ...
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...
NORM emits many different gamma energies that have to be analysed by an expert. Alternatively, artificial neural networks (ANNs) can be used. These mathematical software tools can generalize "knowledge" gained from training datasets, applying it to new problems. No expert knowledge of gamma-ray spectrometry is needed by the end-user. In this work an ANN was created that is able to decide from t...
The linear attenuation coefficient (LAC) and mass (MAC) are most important while studying of radiation, radio-isotopes in dosimentry irradiation materials. In the present work to calculate values different salts samples by using Gamma-ray spectrometry with Photo-Multiplier Tube (PMT) Multi-Channel Analyzer (MCA). 0.123, 0.511, 0.662, 1.17, 1.28 1.33MeV gamma energy rays used for experiment inte...
