Start here if radiation is new to you. This course covers the fundamentals: what alpha, beta, gamma, and neutron radiation are, how they interact with matter, and how we detect and measure them safely. A practical foundation for every course that follows.

How does a crystal turn a gamma ray into data? This course follows the light: scintillation materials, photomultipliers, and the electronics that convert faint flashes into usable spectra. Ideal for anyone selecting or operating scintillation-based instruments.

Special nuclear material has telltale signatures, if you know where to look. Learn the physics behind SNM detection, the challenges of shielding and masking, and the techniques instruments use to separate real threats from innocent alarms.

Compton scattering buries weak peaks in background. Suppression systems dig them out. Learn how guard detectors, coincidence logic, and careful geometry combine to clean up gamma spectra and reveal what standard systems miss.

Operator training for the SAM 950 isotope identifier: startup, screens and settings, source identification, and best practices for reliable measurements in the field. Everything a new operator needs to run the instrument with confidence.
