Alpha particles comprise 2 neutrons and 2 protons. Because of their large mass and relatively slow speed, alpha particles are the least penetrating of the three types of radiation, and can be stopped ...

If you want to measure radioactivity, nothing really beats a Geiger counter: compact, rugged, and reasonably easy to use, they’re by far the most commonly used tool to detect ionizing radiation.

Alpha particle radioluminescence detection and imaging is an advanced optical technique that capitalises on the light emitted when alpha particles interact with air molecules. When alpha particles – ...

A lighthouse is built to shed light on rocky waters, the light turning at the top of a tower to illuminate sections of a dark shoreline that might harm incoming boats. Researchers from Los Alamos ...

Tokyo-based precision components manufacturer Orbray has announced the development of an advanced radiation nuclear detector. This detector is unique because it is based on the company’s proprietary ...

Prof. Erno Sajo of UMass Lowell’s Department of Physics and Applied Physics, in collaboration with researchers from Brigham and Women’s Hospital in Boston led by Prof. Piotr Zygmanski, has developed a ...

The nanoscale radiation detector is a hundred times faster than its predecessors, and can function without interruption. Researchers from Aalto University and VTT Technical Research Centre of Finland ...
