Radiation Damage At The Root Of Chernobyl’s Ecosystems
2014-03-19 19:37:38

Steven Powell, University of South Carolina Radiological damage to microbes near the site of the Chernobyl disaster has slowed the decomposition of fallen leaves and other plant matter in the area, according to a study just published in the journal Oecologia. The resulting buildup of dry, loose detritus is a wildfire hazard that poses the threat of spreading radioactivity from the Chernobyl area. Tim Mousseau, a professor of biology and co-director of the Chernobyl and Fukushima...

Examining X-ray backscatter scanners at LAX airport, an independent task force determines that radiation doses are low, according to new report by AAPM A new report by an independent task force commissioned by the American Association of Physicists in Medicine (AAPM), has found that people absorb less radiation from airport X-ray backscatter scanner than they do while standing in line waiting for the scan itself. Measurements made on two scanners in active use at Los Angeles...

The World Health Organization (WHO) said on Wednesday that radiation levels in Japan's Fukushima district are below the reference level for public exposure in all but two areas. The WHO said in its report that the town of Namie and Itate village, which are located 12 to 18 miles away, were most affected. These towns had doses of radiation levels that reached 10 to 50 millisieverts (mSv). Neighboring towns reached 1 to 10 mSv, while other areas were as low as 0.1 to 10 mSv, according to...

According to a study in the April issue of the Journal of the American College of Radiology, the department of radiology at the University of Colorado in Denver has developed a convenient, pocket-sized reference card to communicate the effective doses and radiation risks of common adult radiologic exams to referring physicians and patients. The Adult Dose-Risk Smartcard is part of the department's ongoing efforts to ensure safe medical imaging. The Adult Dose-Risk Smartcard is intended to...

Why are people so afraid of radiation? Is it the unseen nature of its presence? The long-term possible damage to our DNA? And what about the radiation we are exposed to every single day caused by cell phones, solar flares, and medical equipment? After nuclear power plant accidents in Russia, Japan and the US, the fear of radiation contamination can cause more panic and confusion than the actual radiation. Despite the daily dangers we all face, such as disease, cancer, auto accidents and...

Multiple testing with the cardiac diagnostic imaging technique of myocardial perfusion imaging is common, and in many patients is associated with a high cumulative estimated radiation dose, according to a study in the November 17 issue of JAMA. The study is being released early online because it is being presented at the American Heart Association's annual meeting. Use of medical imaging has grown rapidly in recent years, but along with the potential benefits has come an increase in the...
