Performance Evaluation of the Radiacode 103 Portable Radiation Detector
In recent years, there has been wider availability of radiation survey meters from direct sellers on the Internet, combined with a greater interest in surveying objects and areas for radioactive contamination. With this, we have seen a growth in radiation detector ownership among the general public. These survey meters are often limited to Geiger counters […]
LightLink® – Advances in Detector Technology based on Plastic Scintillators for α, β and γ Radiation
Plastic scintillators coupled with photomultipliertubes (PMT), have served as reliable large-area detectors for α and β radiation as well as large-volume γ detectors for many years. This contribution summarizes conventional plastic scintillation detector technologies and explores the recent strides made in detector technology through the integration of Single-Photon Avalanche Diodes (SPAD) specifically Silicon Photomultipliers (SiPM). […]
Pulse Pileup Restoration Techniques for High Rate Gamma Spectroscopy with LaBr3(Ce) Scintillation detectors
Gamma spectroscopy is limited by the effects of pulse pileup, which occurs when radiation detection events arrive in rapid succession, causing signal contributions from individual events to overlap. Traditionally, pileup events are discarded by a pileup detection algorithm, as the pileup events distort the pulse height spectrum. This mitigates the degradation in energy resolution but […]
Enhancing Accuracy and Reproducibility in Self-Shielded Box Calibrator
The McMaster University Health Physics Department provides radiation safety & health physics support to a wide range of users, both internal and external to the University. Recently, as part of an effort to enhance our services, we obtained a JL Shepherd & Associates Model 89 self-shielded Cs-137 box calibrator. This is an efficient and conventional […]
