For a human, experiencing a mere five grays (Gy) of ionizing radiation for just a few minutes can be lethal. But the bacterium Deinococcus radiodurans is made of tougher stuff. In liquid culture ...

Smith-Purcell radiation arises when a charged particle, typically an electron, travels in close proximity to a periodic grating, thereby inducing electromagnetic emission that is inherently ...

The evaluation of radiation dose in positron emission tomography (PET) is an essential component of modern nuclear medicine. Accurate dosimetric assessment ensures that the diagnostic benefits of ...

This theoretical particle might not only account for the conflicting measurements but could also illuminate how dark matter interacts with the ordinary matter that makes up our visible universe.

However, now we had a new tension: between our simulation and the electron–positron results which had withstood 20 years of scrutiny. How could those 20-year-old results be wrong?

Nanocrystalline (NC) semiconductor materials have previously been studied as a means of increasing the exciton multiplicity upon the impingement of visible light, for applications such as solar cells.

The Section maintains and operates several global isotope data networks for hydrology and climate studies, including the IAEA Global Network of Isotopes in Precipitation and the Global Network of ...

In this paper, we present the first 3D Si MOS-capacitor-based radiation (gamma ray) sensor with high sensitivity and wide dose operation for occupational dosimetry applications. The capacitance ...

New Edition: Principles of Radiation Interaction in Matter and Detection (4th Edition) This book, like the first and second editions, addresses the fundamental principles of interaction between ...
