Developing software for self-absorption correction for gamma spectrometry of soil and water samples based on MCNP5 monte carlo simulations / Eliyeh Zamani …[et al.]

Gamma spectroscopy using high purity germanium detectors, HPGe, is one of the most effective methods in determining the concentration of gamma-emitting radionuclides in the environment. The HPGe detector was simulated using MCNP5 Monte Carlo code, whereby the detector calibration curves were obtaine...

The HPGe detector was simulated using MCNP5 Monte Carlo code, whereby the detector calibration curves were obtained at various geometries and heights, and the appropriate software was designed for efficiency calibration.
