IAEA Study: Five-Star Rating System Can Improve CT Imaging Safety and Reduce Unnecessary Radiation Exposure

IAEA Study: Five-Star Rating System Can Improve CT Imaging Safety and Reduce Unnecessary Radiation Exposure

A new study led by the International Atomic Energy Agency (IAEA) in collaboration with Massachusetts General Hospital and Harvard Medical School in Boston, USA, shows that a five-star rating system can help hospitals optimize image quality, reduce radiation dose, and decrease unnecessary patient radiation exposure in computed tomography (CT) examinations. The study has been published in the European Journal of Radiology. CT imaging uses X-rays to obtain detailed images of internal body structures and is an important tool in diagnosing a wide range of diseases. The study notes that CT image quality is closely related to radiation dose—higher doses typically reduce image noise and improve clarity, but do not always yield additional diagnostic value. How to minimize radiation exposure while ensuring diagnostic accuracy is key to optimizing CT examination protocols.

Russian enterprise develops borated polyethylene material for neutron radiation protection

Russian enterprise develops borated polyethylene material for neutron radiation protection

A neutron radiation protection material developed by Russian company NPO Gelar has obtained relevant certification. The material, named Polikeramoplast-PB, is a borated polyethylene that resembles ordinary gray or black plastic sheets in appearance, but its protective performance derives from the combination of hydrogen and boron. According to reports, the hydrogen in the material effectively moderates fast neutrons, reducing the likelihood of subsequent secondary reactions, while the boron helps absorb moderated neutrons. In contrast, traditional heavy metal materials used for gamma-ray shielding are not suitable for standalone neutron protection, as heavy atomic nuclei have limited attenuation effects on neutrons. The material can be used in radiation therapy room protection systems and combined with lead...

U.S. NRC Proposes Radiation Protection Rule Changes, Removal of ALARA Requirements Sparks Safety Controversy

U.S. NRC Proposes Radiation Protection Rule Changes, Removal of ALARA Requirements Sparks Safety Controversy

The U.S. Nuclear Regulatory Commission (NRC) plans to hold an online public meeting on August 10 to discuss its proposed rule titled "Reforming and Modernizing the NRC's Radiation Protection Framework." The proposal, published on July 15, centers on reexamining the use of the linear no-threshold model in assessing radiation health effects, as well as the as low as reasonably achievable principle—the ALARA principle—derived from that model. Under the proposal, the NRC intends to remove ALARA-related requirements from its regulations and instead adopt a graded dose management framework. This framework would be based on explicit radiation protection thresholds, dose management methods, and acceptable dose measurement approaches. The regulator stated that this move is not about changing exposure standards for workers and...
