In my opinion, based on multiple reporting of collusion between business and government, government cannot be trusted to be honest with the people. They can be trusted to provide big business the validity they need to promote their products.
A Californian university professor of biochemistry said the Obama administration's claim that full-body scanners pose no health risks to air travellers is in "error".
The administration's defence of the controversial machines, which use x-rays to perform what critics have dubbed "naked strip searches" , has "many misconceptions, and we will write a careful answer pointing out their errors", said John Sedat, a University of California, San Francisco (UCSF) professor of biochemistry and biophysics and member of the National Academy of Sciences.
This professor sent a letter to the US government in which he lays out the very real dangers to people who go through these scanners.
I am going to quote extensively from the letter:
The Red Flags
The physics of these X-rays is very telling: the X-rays are Compton-Scattering off outer molecule bonding electrons and thus inelastic (likely breaking bonds).
Unlike other scanners, these new devices operate at relatively low beam energies
(28keV). The majority of their energy is delivered to the skin and the underlying tissue. Thus, while the dose would be safe if it were distributed throughout the volume of the entire body, the dose to the skin may be dangerously high.
The X-ray dose from these devices has often been compared in the media to the cosmic ray exposure inherent to airplane travel or that of a chest X-ray. However, this comparison is very misleading: both the air travel cosmic ray exposure and chest Xrays have much higher X-ray energies and the health consequences are appropriately
understood in terms of the whole body volume dose. In contrast, these new airport
scanners are largely depositing their energy into the skin and immediately adjacent tissue, and since this is such a small fraction of body weight/vol, possibly by one to two orders of magnitude, the real dose to the skin is now high.
In addition, it appears that real independent safety data do not exist.(Imagine my non-suprise? I guess the Whitehouse just took the word of big business) A search, ultimately finding top FDA radiation physics staff, suggests that the relevant radiation quantity, the Flux [photons per unit area and time (because this is a scanning device)]has not been characterized. Instead an indirect test (Air Kerma) was made that emphasized the whole body exposure value, and thus it appears that the danger is low when compared to cosmic rays during airplane travel and a chest X-ray dose. In summary, if the key data (flux-integrated photons per unit values) were available, it would be straightforward to accurately model the dose being deposited in the skin and adjacent tissues using available computer codes, which would resolve the potential concerns over radiation damage.
Our colleagues at UCSF, dermatologists and cancer experts, raise specific important concerns:
• A) The large population of older travelers, >65 years of age, is particularly at
risk from the mutagenic effects of the X-rays based on the known biology of
• B) A fraction of the female population is especially sensitive to mutagenesis provoking radiation leading to breast cancer. Notably, because these women,
who have defects in DNA repair mechanisms, are particularly prone to cancer,
X-ray mammograms are not performed on them. The dose to breast tissue
beneath the skin represents a similar risk.
• C) Blood (white blood cells) perfusing the skin is also at risk.
• D) The population of immunocompromised individuals--HIV and cancer
patients (see above) is likely to be at risk for cancer induction by the high skin
• E) The risk of radiation emission to children and adolescents does not appear to
have been fully evaluated.
• F) The policy towards pregnant women needs to be defined once the theoretical
risks to the fetus are determined.
• G) Because of the proximity of the testicles to skin, this tissue is at risk for
• H) Have the effects of the radiation on the cornea and thymus been determined?
Hmm, it is almost like this is a government blessed cancer causing machine?!
And isn't it great that Janet Reno recently announced that more of these cancer causing devices are coming your way....
John Tyner, a software engineer in California, refused to go through the extra security measures now in place at the San Diego airport this past weekend. When the 31-year-old refused the controversial search, he was ejected from the airport.
“I don’t think that the government has any business seeing me naked as a condition of traveling about the country.”
John Tyner said that only his wife and doctor are “allowed to touch his groin and that if it were not the government doing this, it would be considers a sexual assault.”You can also read the personal testimony of John Tyner here. This blog appears to be the work of John Tyner. Of course, I cannot be certain of that, but it looks as if that is the case. The video is available there also.
