A free neutron outside a nucleus is not stable. It undergoes beta decay at a probability. Over time, the number of free neutrons decreases exponentially at a time constant, which is called the neutron ...

Ever since the Fukushima nuclear reactor disaster, there has understandably been an upsurge in the sale of consumer radiation-detecting devices. Most of these gadgets are variations on the Geiger ...

Additive manufacturing techniques like fused deposition modeling, aka 3D printing, are often used for rapid prototyping. Another advantage is that it can create shapes that are too complex to be made ...

Investigators report the discovery of a new material that may be able to directly detect dark matter. The material, known as a scintillator, should be sensitive to dark matter that is lighter than a ...

An array of photomultiplier tubes, used to detect faint sources of light, mounted inside the steel tank of the Eos detector. The photomultiplier tubes will eventually be submerged in water admixed ...

Canadian technology start-up Medscint is partnering with researchers at UMC Utrecht to develop a real-time dosimetry platform for MR-guided adaptive radiotherapy Optical innovation, clinical ...

In 2024, the T2K Collaboration started to collect new neutrino data following several upgrades to the experiment that included new types of detectors. One of these, called SuperFGD, has a mass of ...

An unconventional telescope spreads across Utah's dry Bonneville lake bed. Made up of hundreds of giant rusty detectors, the instrument studies cosmic rays, the high-energy particles that come from ...
