For some passengers proceeding by way of the brand new full-body scanner at Lindbergh Field, coverage to radiation is really a concern.

"I do not know how much it places out, that hasn't been disclosed, has it?" asked 1 passenger.

Three U.S. senators on the Senate Committee on Homeland Security and Government Affairs wrote a letter to your Department of Homeland Protection and also the Transportation Security Administration stating, "The problem of radiation … has not been adequately addressed by TSA."

Dr. Steve Smith of Rancho Bernardo stated that the safety problem is misguided.

"This is totally protected; there is no problem in any way," he stated.

Smith is the original developer in the technologies termed backscatter X-ray due towards the fact it touches the skin then scatters back to the X-ray source.

"The sum of radiation utilized in these units is miniscule," stated Smith.

Twenty years in the past, Smith created a prototype of your entire body scanner that is certainly now used in 51 airports today, such as Lindbergh Subject. He said it is secure for pregnant females, youngsters and also frequent fliers.

"The real quantity on it truly is three micro rems. Compared, organic background radiation is about 300 micro rems per day," he explained.

Smith stated the X-rays are usually not sturdy enough to penetrate all the way to bones or organs like more powerful professional medical X-rays do.

Dr. Bette Blankenship, a health-related physicist with Sharp Healthcare, agreed and said of the radiation exposure, "This unit is very minimal, nearly immeasurable.

Blankenship mentioned that the backscatter X-ray publicity prior to the flight is significantly less than the coverage during the flight itself.

"As you take maybe a six-hour flight, you're going to have 600 instances the energy deposited in you than from this type of system," she claimed.
