Sellafield Nuclear Plant a Public Safety Threat

Photos of radioactive waste storage ponds in a shocking state of neglect at the UK’s Sellafield (previously Windscale) nuclear reprocessing plant reveal that they have been severely neglected for decades. Cracked concrete tanks—the largest measuring 20m by 150m with a depth of 6m—have been left open to the elements since the mid-1970s despite high levels of radioactivity. Informed readers may recall that Windscale was the scene of one of Europe’s most serious nuclear accident several decades ago “The Windscale Fire”...

Medical Imaging Radiation Dose Chart

Here’s a great infographic, published by Phillips Medical Division, illustrating the typical dosage levels one is likely to experience with various types of medical imaging. The full range of radiation dose is charted, from ambient background to the maximum annual allowable dosage for radiation workers.  

Recent Reactor Scare Revives Chernobyl Fears

One of the reactors in Europe’s largest nuclear power plant in southern Ukraine suffered an accident that triggered an automatic shutdown this week. Reports suggest that damage occurred to a transformer in one of the 1000-megawatt reactors at the Zaporizhye plant, which provides over one-fifth of the country’s electricity.  Most of us remember in April 1986, the world’s worst nuclear disaster. Technicians lost control of nuclear fission reactions in the reactor core and heat rose quickly until pressure built up...

Medical Scans Not Dangerous

There are a lot of things to be afraid of in this world. Getting a medical scan to see if you need help is not one of them.  Indeed preventing beneficial medical procedures like mammograms and CT scans by claiming, incorrectly, that the procedures themselves can cause cancer is counter-productive and can put patients at risk. A recent article, Hidden Dangers of Medical Scans, says more and more doctors are worried that medical imaging and other tests involving X-rays are...

Fukushima Radioactivity along West Coast

It was only a matter of time but scientists at the Woods Hole Oceanographic Institute (WHOI) found the trace amounts of telltale Fukushima radioactivity as part of their ongoing monitoring of natural and human sources of oceanic radioactive contamination. “We detected cesium-134, a contaminant from Fukushima, off the northern California coast.  The levels are only detectable by sophisticated equipment able to discern minute quantities of radioactivity,” said Ken Buesseler, a WHOI marine chemist, who is leading the monitoring effort. “Most...
