Cutting down on cancer risks from medical radiation
….Radiation is a known carcinogen. Therefore, before exposing a person to this amount of radiation, the pros and cons of performing a CT scan must be carefully considered……
Dr. Murray Feingold: Weighing in on radiation controversy – Chillicothenews, 20 July 2010, “……. Each year about 75 million CT scans are performed. But how safe are they?. CT scans use radiation; MRIs do not. The amount of radiation varies depending upon the part of the body being examined. The radiation dose is about 100 to 500 times greater than regular X-ray examinations, maybe even higher when specialized CT studies are done…….Radiation is a known carcinogen. Therefore, before exposing a person to this amount of radiation, the pros and cons of performing a CT scan must be carefully considered……
A major issue is that too many CT scans are now being preformed and this number needs to be reduced.
In a survey of Massachusetts physicians, it was determined that 28 percent of diagnostic imaging referrals for CT scans and MRIs were done because the doctors were concerned about malpractice suits.
Then, radiologists who interpret the CT scan may order even more images to reduce their uncertainty.
Another important issue is the radiation dose. Researchers believe that in most cases, it can be reduced. Previous studies have shown that reducing the dosage by 50 percent usually does not decrease diagnostic accuracy.
More attention must be paid to the inadvertent radiation that is sometimes released by the CT scanning equipment.

Zoom webinar – “Nuclear Winter: The Environmental Consequences of a Nuclear Exchange.”
April 7th at 11:30 am PST / 2:30 pm EST
Nuclear Winter: The Environmental Consequences of a Nuclear Exchange”
Join us for an informative webinar with renowned atmospheric scientist, Professor Brian Toon, as he discusses the environmental risks and global impacts of a nuclear war. Despite the potential damage caused by the blast from even small nuclear weapons, many countries continue to invest in and expand nuclear arsenals. Professor Toon will provide a scientific assessment of civilian fatalities, agricultural failures, climate concerns, and complications with food supply that would follow any international nuclear conflict. We need to plan how to prevent nuclear conflict and avoid catastrophe. Politicians and military planners must be made aware of global climate and agricultural complications that would ensue. Don’t miss this opportunity to learn from, and engage in, this vital conversation
The Road to War brings a sharp focus to why it is not in Australia’s best interest to be dragged into a war with China which will almost inevitably go nuclear very quickly. The filmmaker has interviewed some of Australia’s senior foreign policy analysts who have vast experience behind them in analysing what really is going on here as the United States rattles its sabres with China. And sets us up to be its proxy, like the poor Ukranians have been fed into the Meatgrinder. So America can remain the Top Dog. The Road to War reveals how the United States through its spy base at Pine Gap and by stationing six nuclear capable B52 bombers in the Top End (without permission from the traditional owners) is making Australia a prime nuclear target if the current war of words suddenly melts down into full scale war.
The Road to War shows the implicit connection between Carbon emissions (the US military uses a whopping 70% of America’s annual petroleum to move its armies and vast War Machine around the globe to its 800+ military bases..but under a loophole wangled at Kyoto, the US military does not have to report its C02 annual emissions). The Road to War starts screening at selected cities and regional centres in March. See the trailer end for details.
