A Pinpoint Beam Strays Invisibly, Harming Instead of Healing
Source: NYT



Marci Faber was one of the three patients. She had gone to Evanston Hospital in Illinois seeking treatment for pain emanating from a nerve deep inside her head. Today, she is in a nursing home, nearly comatose, unable to speak, eat or walk, leaving her husband to care for their three young daughters. Two other patients were overdosed before the hospital realized that the device, a linear accelerator, had inexplicably allowed radiation to spill outside a heavy metal cone attachment that was supposed to channel the beam to a specific spot in the brain. One month later, the same accident happened at another hospital.

The treatment Ms. Faber received, stereotactic radiosurgery, or SRS, is one of the fastest-growing radiation therapies, a technological innovation designed to target tiny tumors and other anomalies affecting the brain or spinal cord, while minimizing damage to surrounding tissue.

Because the radiation is so concentrated and intense, accuracy is especially important. Yet, according to records and interviews, the SRS unit at Evanston lacked certain safety features, including those that might have prevented radiation from leaking outside the cone.

....

In the last five years, SRS systems made by Varian and its frequent German partner, Brainlab, have figured in scores of errors and overdoses, The New York Times has found. Some mistakes were caused by operator error. In Missouri, for example, 76 patients were overradiated because a medical physicist did not realize that the smaller radiation beam used in radiosurgery had to be calibrated differently than the larger beam used for more traditional radiation therapy.

2. At one time, there were only a couple of hospitals
that offered pin point radiation.A friend who was familiar with Sloan Kittering, one of the hospitals, said never go to a hospital for it unless they were experienced. Pin point radiation cuts out a lot of the ugly side effects of radiation treatment for cancer. In the case of one family member, it would have saved her life.

5. For comparison, consider the untested, unmonitored TSA scanners & their untrained operators
Edited on Wed Dec-29-10 08:30 AM by Divernan
You may have missed some of the recent stories about TSA's bogus claims re the safety of their scanners.

http://www.aolnews.com/2010/12/20/aol-investigation-no-proof-tsa-scanners-are-safe/


"The TSA ticks off a litany of groups that it says are involved with determining and ensuring the safety of the controversial devices, including:

* The Food and Drug Administration
* The U.S. Army Public Health Command
* Johns Hopkins Applied Physics Laboratory
* The Health Physics Society

However, AOL News has found that those organizations say they have no responsibility for the continuing safety of the alternative to TSA's grope. Further, the Homeland Security agency refuses to release exposure data to top non-TSA safety experts eager to evaluate any risk."

As the linked article details, all of these groups said they have no responsibility to monitor the safety of those passing through airport scanners.

THE FDA: Specifically, the FDA has NOT field-tested any of these scanners OR the manufacturer and has no legal authority to require owners (such as TSA) of non-medical x-ray devices to provide access for routine testing.

THE ARMY: it states it sent two person teams to "survey" scanners at only three airports, Boston, LA and Cincinnati. That was all that the TSA asked them to do. The Army noted that none of the machines it examined had the required warning labels.

JOHN HOPINS APPLIED PHYSICS LAB: Its work did nothing to ensure the consistent safety of those exposed to the radiation from the scanners.
"APL's role was to measure radiation coming off the body scanners to verify that it fell within standards. We were testing equipment and in no way determined its safety to humans," Helen Worth, head of public affairs for the Johns Hopkins lab, told AOL News.

"Many news articles have said we declared the equipment to be safe, but that was not what we were tasked to do," she added. Moreover, the study said APL scientists were unable to test a ready-for-TSA scanner at their lab because the manufacturer would not supply one. Instead, the tests were performed on a scanner cobbled together from spare parts in manufacturer Rapiscan Systems' California warehouse.

"The system evaluated may be configured different than the system deployed to the operational environment," the report said. It added that the APL found two areas in the testing mock-up where escaping radiation could cause exposure to the public that exceeded the annual safe limits."

THE HEALTH PHYSICS SOCIETY: states that it did not and does not monitor the safety of TSA's devices -- only that if the devices operate as promised, safety should not be an issue, Howard Dickson, the Society's immediate past president, told AOL News.

In a related article, we learn how inadequate is the training received by TSA employees operating said scanners, particularly as compared to other countries' operators.

http://www.aolnews.com/2010/12/20/expert-scanner-training-more-intense-outside-of-us/

Headline: Expert: Scanner Training More Intense Outside of US


The full-body scanners have either been deployed, or are being seriously considered for use, in Canada, Australia, Japan, South Korea, China, Hong Kong, Nigeria, India, South Africa and most of the European Union. In those countries, the personnel are extensively trained and understand radiation, how the X-ray devices work and what can happen if the calibrations are wrong, according to an international radiation safety expert.

The Government Accountability Office told Congress that the training for the average TSA monitor is about a week and a half in classrooms. And even then, investigators found that trainees often did not have time to complete the reading for the courses, it said. "The staff is encouraged to simply sign off on the materials and receive credit for taking the courses without providing evidence of reading or understanding the information," the report said.

Also, according to that report, the entire process seems hodgepodge. "The agency does not have documented standard processes to update training based on current information, such as the results of officer testing," it said. "While TSA officials explained they have a process in place to guide training enhancements, they acknowledged the process is informal and not documented."

The international consultant also said that TSA personnel at the scanners don't even wear radiation detection devices.
Next time you're in the emergency room or at a nuclear power plant, you'll see that everyone involved with radioactive material wears a small dosimeter to monitor how much radiation he or she is receiving while working near the source.
AOL News asked the TSA why its personnel don't wear the radiation detectors. The TSA has yet to answer.

7. Statistically speaking
At least a few TSA screeners are going to come down with cancer every year.

It's going to be interesting when someone/somebody gets sued over not providing dosimetry.

This is just a lawsuit waiting to happen.

13. The reason they're not giving radiation dosimeters is so they won't have any proof
Edited on Wed Dec-29-10 08:43 PM by Divernan
upon which they or their survivors can base lawsuits. If I were in such desperate financial straits as to work for TSA around these machines, I would wear a dosimeter under my uniform (if they can work that way). Bet you anything the workers have been forbidden to wear them, even if they pay for them personally. Remember when service people in Iraq had to provide their own flak jackets? Our govt. gets more pathetic by the day.

9. Citizen, just asking that question puts you on the list for re-education
I am dispatching the Department of Redundancy Department and the Natural Guard to your location. Citizen, do not atempt to leave your immediate area, we are taking you for your own good, All is well.

All Hail the Military-Industrial Complex, and its market forces at work.

8. The saddest part of this to me is that it is so easy to prevent.
Radiation is highly detectable and upon detection the machine could be shut down almost instantly before large areas of healthy tissue are destroyed. There's no need for accidents like this to happen and the benefits of beams for tumors is irreplaceable in effective medical treatments.

10. WAS
the doctor being overworked. How many procedures was he and the staff involved in. Is he and the staff subject to drug tests for a mistake of this magnitude? CDL drivers are routinely tested and always tested when there is an accident. These are some and not all questions that need answers.
