AIR TRAVEL RADIATION FAQ

What Airports have Scanners?

Are body scanners mandatory?

Are body scanners mandatory?

At this time scanners are still optional in the US, with the exception that on 22 July 2010 El Paso International airport blocked the metal detectors forcing all into the scanners.  Plans were announced by TSA Chicago in spring of 2010 to make scanners MANDATORY.  TSA has introduced the “enhanced” pat-down to encourage scanner “voluntary” compliance.  This puts the public in the difficult position of choosing between a grope, radiation, fines or more dangerous car travel.  We feel this policy is a health risk to the public and particularly dangerous to children and expecting mothers we hope the policy will be reversed.
 
Colorado lawyer Gary Fielder,  has refused the scanner and pat down at a Douglas country Colorado courthouse using AIT equipment. Who's filed a lawsuit against the TSA on the issue -- and there's video proof this isn't a new issue for him, as you'll see in this link
 
TSA/DHS is in the process of installing 1800 more naked body scanners by 2014 at bus stations, railway stations and other entrance points for mass transportation and sport venues such as the supper bowl.
 
For your safety we recommend you "Opt Out" of the Advanced Imaging Technology (ATI).  The security area is radioactive or radio "warm" from  ATI equipment emissions and leakage from luggage x-ray equipment.  At this time the ATI manufactures and TSA/DHS has not released actual radiation doses, independent researchers are estimating the actual dose is 10-20 times greater than the "recommended"  levels.        

When confined in an AIT machine, you can no longer maintain a clear line of sight to your property.  Under these conditions, your property is susceptible to theft please be especially mindful of your wallet, jewelry, and laptop.  Reports of cash, jewelry and laptop thefts are unfortunately common at security areas.

Will the shield trigger the metal detector?

The short answer is No.  Metal detectors use two primary detection methods "eddy current" and field distortion from iron or ferromagnetic materials.   Our patent pending shield is made from 8 layers of proprietary powdered elements suspended in polymers designed to minimize eddy currents, therefore it not easily detected with eddy current methods.  Second, the shield is designed free of toxic lead and field distorting ferromagnetic materials.   The shield was specifically design to not interfere with conventional metal detectors, while retaining superior x-ray and Terahertz (mm-wave) absorbing properties.

Can You "OPT OUT"?

The short answer is YES.  That being said TSA really does not want to pat you down it is time consuming and people find it justifiably degrading.  So they added the "Enhanced" pat-down to encourage voluntarily compliance and get you in the scanner.  
 
For your safety we recommend you "Opt Out" of the Advanced Imaging Technology (ATI).  The security area is radioactive or radio "warm" from  ATI equipment emissions and leakage from luggage x-ray equipment.  Our products still give you protection from x-rays in the security area and some protection from cosmic radiation in flight.    At this time the ATI manufactures and TSA/DHS has not released actual radiation doses, independent researchers are estimating the actual dose is 10-20 times greater than the "recommended"  levels.       
 

Are more powerful x-ray systems in use or planed?

New forward Scatter Total recall Scanner
Conpass System
Industry experts are discussing plans for implementing more powerful systems to look through you, like "Total Recall" style whole body chest x-ray. As of 2010 BBC reported New Castle airport in England has installed a transmission system like the one above in 2008.  Note where the BBC reporter places his hands at the end of the short video.  This system was originally designed for used in prisons, and diamond mines and are now installed in airports in Korea and England.   We feel this type of system like the backscatter machine is far too dangerous for general screening.   

How much of a dose do you get flying  or similar craft?

Concord which of course no longer flies, typically operated at 50,000 ft.  altitude passenger, crew dose 1 mrem (1000 urem) per hour.

Does the dose change with latitude?

Yes, typical high latitude dose is 2X to 3X the dose, compared to equator, due to Earth's magnetic field, which deflects charged particles. Source:

Does the airline travel dose change over time?

Yes, the suns output changes with an 11 year cycle.  Also, during periods of high sunspot activity, dose can increase 5X, 10X or more due to solar flare(s).  
 

Has the dose for passengers and crew been measured?

Yes, several both shorter-haul, and long-haul commercial flight doses have been measured. One actual measured (not Concord) flight: Paris to Tokyo in 1996 was 0.66 mrem, 660 urem total dose to each passenger(s) and crew for this long-haul flight.
 

Do I receive a greater dose living or working at high altitudes?

Yes, even at ground level, cosmic radiation is part of our normal environment. The Earth's atmosphere absorbs most of this radiation, so its intensity is least at sea level. For flying or living at 6,000 feet (1,800 m)— the calculated cosmic-ray dose rate at this altitude at high geographic latitude is about 0.0001 millisievert per hour. It would, therefore, require 10,000 hours of flying at this altitude to reach the 1 millisievert annual limit recommended as a maximum for members of the public exposed to ionizing radiation. It should also be noted that exposures well above this 1 mSv limit are not "dangerous." However living at this level is 8,760 hours very close to the 10,000. This does not include the radiation from isotopes in the soil and or building materials.

Will the radiation shield be felt during a security pat down? 

Our thin flexible (1.5mm) shield material is securely bonded to the garment stretches and conforms to body contours therefore is difficult to feel with the back of the hand, no unsightly bulges are visible with tight fitting garments.   Being thin and flexible it does permit detection of large hard objects underneath, the shield was designed to not interfere with professional pat-downs.
