Radiacode Calibration Using Thoriated Glass via Mobile Device (Android and Apple)

Thoriated glass lenses—sometimes used in vintage cameras to reduce chromatic aberration—may contain up to 30% Th-232 by mass. For this analysis of Th-232, the Radiacode will rely on gamma emissions from its decay products, with a focus on the 238.6 keV peak produced by Pb-212, as well as the 583 keV and 2614 keV peaks […]

Autunite Stabilization Procedure

Autunite is a metamict mineral, meaning it can disintegrate over time due to radioactive decay and water loss, which weakens its crystal structure. Stabilization with a consolidant can halt this natural disintegration process by infusing the specimen with an acrylic polymer. The two most commonly used consolidants for stabilizing autunite are Paraloid B-72 and Butvar
