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 ...

Synchrotron radiation sources generate highly brilliant light pulses, ranging from infrared to hard X-rays, which can be used to gain deep insights into complex materials. Using concrete examples, ...

An AU desiring to purchase radioactive materials or ionizing radiation sources must receive approval from the Radiation Safety Office. This ensures compliance with license requirements, proper ...

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 ...

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 ...

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 ...

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 ...

Roentgen’s discovery of X-rays in 1895 was followed by a considerable burst of research: within a single year, approximately 1000 X-ray research papers were published. Yet, the scientists of the time ...

Radiation therapy uses carefully targeted beams to destroy cancer cells while minimizing damage to healthy tissue. At Fred Hutch, patients have access to a full range of advanced radiation treatment ...
