Expertise
Characterisation of gamma spectrometry detectors using MCNP
Improve your assessments of radioactive activity from your gamma spectrometry measurements.
Reduce costs associated with overestimating the radioactivity of waste and environments, as well as uncertainties surrounding these estimates.
Our innovative and rapid approach is based on unique software, combined with our expertise in experimental measurements, Monte Carlo modelling and gamma spectrometry data processing. This characterisation solution enables players in the nuclear industry to accurately assess radioactive activities and their uncertainties. The characterisation obtained (using MCNP) from our detectors ensures that potential overestimations or underestimations are minimised, providing reliable results for decision-making.
Detector characterisation tool with MCNP
Radeo offers an innovative solution for the multi-parameter characterisation of gamma spectrometry detectors. This tool reduces discrepancies between measurements and simulations by adjusting unknown parameter values (see example 1). The software thus determines reliable efficiency curves and rigorously assesses the uncertainties associated with each parameter.
The method is based on a combination of Monte Carlo code (MCNP) and a powerful AI algorithm that automatically adjusts up to ten unknown parameters related to the internal geometry of the detector.
Included deliverables:
- measured and simulated efficiency curves (see example 2),
- the complete MCNP model of the detector,
- a detailed technical report.
This method applies to all types of gamma spectrometry detectors (semiconductor detectors, particularly CZT detectors and scintillators).
Automated model adjustment platform
Based on a set of calibration measurements carried out by us at strategically selected positions. Our software tool allows unknown parameters to be adjusted in order to reproduce the experimental efficiency curves. Our method is based on the MCNP code and provides accurate modeling of radiation-matter interactions, shielding effects, and detector geometry.
The results enable more reliable efficiency calculations, more accurate assessments of radioactive activity in your environments, and a reduction in the need for field testing.
