Patients do not understand the cancer risks of CT scan radiation
patients in general have a poor understanding of CT scan radiation exposure and underestimate the possible effects of their previous CT scan experiences.
Patients Underestimate Radiation Risk from CT Scans: Study – AboutLawsuits.com, 20 Dec 10, Only about 25% of patients understand the true risks of radiation when undergoing computed tomographic imaging (CT scans), according to the findings of a new study on the public’s perceptions of radiation risk and exposure.

U.S. airport radiation scanning operators poorly trained, poorly protected
Expert: Scanner Training More Intense Outside of US, AOL News, Andrew Schneider, 20 Dec 10, “………Transportation Security Administration screeners in the U.S. receive less training than cast members and full-time employees at Disney World, who train for several weeks or even months, depending on the position involved, according to the expert, who spoke to AOL News on condition of anonymity because he has contractual agreements with various governments and airlines.

Public better protected from radioactive pets than from radioactive people
Radiation Rules Differ for Humans and Pets NYTimes.com, by Matthew Wald, 9 Dec 10, WASHINGTON — One group receiving treatment for a thyroid disorder is given a radioactive drug that makes the patients a potential hazard to children or pregnant women for several days. Still, doctors usually send them home immediately after treatment. Continue reading

Health professionals address problem of medical radiation and cancer risk
Too much radiation can cause cancer. The average American’s total radiation exposure has increased in recent decades because of the increased use of new imaging tests, particularly CT scans, raising questions about possible increased cancer risk.

Increased use of CT scans carries radiation risks
CT Scan Use Surging in Hospital ERs Study authors extol benefits, but note concerns about increasing exposure to high-dose ionizing radiation Bloomberg, By Alan Mozes Nov. 29 — The use of CT scans as a diagnostic tool is surging in emergency departments across the United States, new research indicates.In the 13-year period leading up to 2007, CT scan use in ERs increased by nearly sixfold, the study team found.The trend has raised concerns about the potential risks posed by more frequent exposure to the ionizing radiation emitted by CT scanners, they added…CT Scan Use Surging in Hospital ERs
Airport scanning and the cancer risk
“Even if the risk associated with an individual going through a scanner one time is miniscule,” he said, “when you multiply that miniscule risk by say two or three hundred to correspond to the potential annual usage of a commercial air crew or a very frequent flier, the estimated risk may still be small, but it is no longer `miniscule.`”
Can You Get Cancer From Airport Scanners?, The SOP, 29 Nov 10, Jerome R. Corsi A Columbia University expert in radiation today confirmed that it is quite “likely” that the radiation from screening machines being installed nationwide by the Transportation Security Authority to use on airline passengers will cause cancer.
The word comes from David J. Brenner, of Columbia`s Center for Radiological Research, and whose research involves radiation biology, low dose risk estimation and radiotherapy.
There`s no use depending on TSA “research” that denied or minimized that risk because those results have been bought and paid for, he noted…….
Join tens of thousands of Americans in a petition demanding action against the intrusive airport screening procedures implemented by Janet Napolitano and send a letter to Congress, President Obama and others telling them exactly what you think about the issue.
Brenner undermined Department of Homeland Security statements that X-ray imaging scanners are safe by explaining the government`s research is not peer-reviewed.
“We know the radiation dose is very low, but there are different views about how low is low,” Brenner, a Ph.D., told WND.
“TSA is basing its claims for safety on research the government has commissioned,” he said, “not on peer-reviewed independent studies published in scientific journals.”
He cited a report by three scientists from Arizona that is peer-reviewed that concluded that cancer is a public health “concern” from even low doses of radiation.
The article, “The Dose from Compton Backscatter Screening,” was co-authored by Peter Rez of the Department of Physics at Arizona State University in Tempe, Robert L. Metzger of Radiation Safety Engineering, Inc., in Chandler and Kenneth Mossman of Scholl of Life Sciences at Arizona State University in Tempe.
It was accepted for publication October 7, 2010, in the Oxford “Journal of Radiation Protection Dosimetry,” a peer-reviewed journal.
“The major public health effect of concern at low doses of ionizing radiation is cancer,” Rez, Metzger and Mossman wrote. “It is not possible to determine reliably whether a radiogenic risk is present in an X-ray screened population because of the high spontaneous incidence of cancer and the multifactorial nature of disease causation.”
Rez, Metzger and Mossman also pointed out that the health risk increases if the TSA X-ray equipment malfunctions, noting that, “serious consideration should be given to the possibility of unintended and unnecessary doses to passengers due to malfunctioning equipment.”
“Even if the risk associated with an individual going through a scanner one time is miniscule,” he said, “when you multiply that miniscule risk by say two or three hundred to correspond to the potential annual usage of a commercial air crew or a very frequent flier, the estimated risk may still be small, but it is no longer `miniscule.`”
His greatest worry is the overall population risk.
“The bigger concern is indeed the overall population risk,” he argued. “To illustrate generally what I mean here, suppose some activity involves a very small cancer risk, and a very large number of people are exposed to the risk, then the chances are that some of them would get cancer as a result of that activity, even though the individual risk is very small.”……..
Medical radiation risks must be explained to patients
CT imaging, though, can produce as much as as 500 times the radiation of an X-ray, and experts have estimated that as many as 20% in Canada are ordered needlessly. U.S. studies suggest the risk of cancer from a single CT scan ranges from one in 2,000 to one in 300, depending on the dose and other factors.
Patients must be told of CT-scan dangers: doctors, Tom Blackwell, National Post , Nov. 26, 2010 As CT scans and similar procedures are ordered increasingly often, doctors should be forced to tell patients about the potential radiation-based cancer risk, two Canadian physicians have urged in a major U.S. medical journal.
