Researchers have now succeeded in producing an extremely simple and compact source of terahertz radiation: An oscillator with double resonant-tunneling diodes. Its radiation power significantly ...

Radiation can be defined as energy traveling through space. There are two types of radiation, ionizing and non-ionizing, which are differentiated by how they interact with matter. Non-ionizing ...

UV radiation is invisible to the eye and it is non-ionizing form of radiation in the 100 nm to 400 nm wavelength region of the electromagnetic spectrum. UV radiation is arbitrarily divided into UV-A ...

Radioactive sources contain radioactive material of a particular radionuclide (an unstable form of an element emitting radiation), which can vary based on the application for which the source was ...

As the COVID-19 pandemic continues to severely impact all aspects of human activities, so too has it impacted the regulatory oversight of radiation sources which are used mainly in medicine, industry ...

In the ruins of Chernobyl’s shattered reactors, something unexpected has taken root. Thick black mats of mold are thriving ...

Congress asked the National Academies to review the civilian uses of radiation sources that contain radionuclides and the potential replacements for sources that pose a high risk to public health or ...

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 ...

Galactic Cosmic Rays (GCR) and unpredictable Solar Particle Events (SPEs) pose a significant threat to astronauts during exploration missions to the moon or Mars. Each radiation source has a unique ...

The purpose of this Sandia National Laboratories' sponsored study is to support existing and future activities under the National Nuclear Security Administration (NNSA) Office of Radiological Security ...
