Researchers from North Carolina State University have developed a new technique that allows them to assess radiation exposure in about an hour using an insulator material found in most modern electronics. The technique can be used to triage medical cases in the event of a radiological disaster. (more…)
Greater awareness and careful usage are bringing down the numbers of pediatric CT scans and cutting radiation exposure. Parents should weigh the benefits and risks.
(September 2013) If your child had a CT scan last year—perhaps to assess damage from a hockey injury or rule out appendicitis—he or she added to a huge statistic: more than 4 million pediatric CT scans were performed in the U.S in 2012. (more…)
Berkeley Lab scientists have helped to develop a tiny chip that has big potential for quickly determining whether someone has been exposed to dangerous levels of ionizing radiation. (more…)
*Berkeley Lab Researchers Developing Promising Treatment for Safely Decontaminating Humans Exposed to Radioactive Actinides*
The New York Times recently reported that in the darkest moments of the triple meltdown last year of the Fukushima Daiichi nuclear power plant, Japanese officials considered the evacuation of the nearly 36 million residents of the Tokyo metropolitan area. The consideration of so drastic an action reflects the harsh fact that in the aftermath of a major radiation exposure event, such as a nuclear reactor accident or a “dirty bomb” terrorist attack, treatments for mass contamination are antiquated and very limited. The only chemical agent now available for decontamination – a compound known as DTPA – is a Cold War relic that must be administered intravenously and only partially removes some of the deadly actinides – the radioactive chemical elements spanning from actinium to lawrencium on the periodic table – that pose the greatest health threats.
