Body scanners and children ??

[sam_gordon]

why would anyone want more when it doesn't serve a medical purpose?

So they can fly?

 

[*Meagan*]

For my industry, there have been studies of the amount of radiation received during the security screening process and during the rest of the traveling experience. A person receives far more radiation on board a flight at cruise altitude (35,000 ft asl) than they do going through the scanners.

I know this I stated that in a previous post.

Did you read my post? I am not concerned with the scanners. I work with radiation every day. That is the radiation I worry about. Keeping my occupational dose down.And keeping my patients medical dose down. Time.distance.shielding. Which I do or I would not be able to work in the field I do.

ETA - I find it interesting that the radiology docs and the radiology association recommend limiting exposure to xrays. why would anyone want more when it doesn't serve a medical purpose?

You are right I'm not an expert but I am educated.
I personally think we as people who work with radiation on a daily basis know the difference between the "radiation" per say. Were more concerned with patients and radiation that were are distributing, we control that aspect.. Not about some radiation that may occur at an airport scanner. And we also understand you will receive more radiation living in your home, flying in a plane, or having smoke detectors. So its not concerning!

I know I have an occupational dose (because of my field of work) and a lifetime exposure dose. Scanners do not even make the charts but here are some numbers for you:

You receive 0.5 mrems per hour flying..
I receive 47 mrems a year for living at 4400ft ASL.
I have a smoke detector in my house (I have 3) 0.024 mrems.
If you have a crown in your mouth or porcelain teeth there is another dose. Have a microwave add a check mark. Live with in 50 miles of a coal or nuclear power plant add another check mark.

My occupational dose per year can not exceed 5 rems which is 5000 mrems..
I have not even come close to this number and I have been doing this for 5 years. And I work with radiation daily. My last full reading which includes lens of eye, skin of whole body, organ, extremity, whole body dose
was 2.1478 mrems (for 6 months)

The average person is exposed to 360 mrems a year and some do not even come close to that number.

Radiation is ALL around you. Its just how this world works.

OKay, we have someone that works in this industry, someone who has done her homework and looked into the 'issue'. She feels there is no threat here. Or at least one that she is not bothered by.
Why do you insist on arguing with every single person who posts here with a differing opinion??? You are not going to be happy until some official study shows that we are all going to lose all our hair and start glowing if we use these scanners.
I am happy to have someone, in the industry, come here and tell us that they really have no issue with the scanners. She does make some very valid points.

I trust I am permitted to ask a question or two.

And why I should I add to my exposure of ionizing radiation as a condition of travelling by airplane?

I also wonder about the numerous ionizing radiation sources (none of which have the "shields" that a medical xray device has) in a TSA checkpoint. Some places are pretty cramped.

...I have a smoke detector in my house (I have 3) 0.024 mrems.
...Have a microwave add a check mark

Is that figure per smoke detector, or for all three? At what distance was this measurement made?

What's the source of ionizing radiation in a microwave oven?

Once again... because you want to fly. The searches are a condition of flying. Don't want the searches, don't fly.

I'm not a radiation physicist or I would have all these numbers for you.

The smoke detector number was for all three. I do not know how tall your ceilings are but it is a general number probably for general ceiling height!

To be blunt: Are you undergoing some sort of radiation treatment or therapy or have you in the past? And that is why this bothers you so much???

thanks for sharing Holt's letter: very informative. What is the layered approach mentioned being used in Isreal?

 

[ironz]

As a radiologist...the physician that interprets the xrays...and with all due respect to Meagan....
Please review your radiation physics.
Medical imaging uses a penetrating xray beam. That's how we see through the patients. The beam comes out of the machine and penetrates the body to reach a detector on the other side.
That is not how backscatter works. The photons are delivered to the skin.
Please read this article, everyone. There is a reason that some scientists are still questioning the dose. The numbers bandied about were not from an independent peer reviewed assessment.

Also...let's keep in mind that we don't know that the TSA is keeping the machines calibrated with the attention that medical devices receive.

MYOB . . . I don't want unnecessary exposure to ionizing radiation.

Might it be that there is no ionizing radiation from a microwave oven?

The day I was there, the line I went thru everyone I saw went thru the scanner. El Paso is not a large airport.

I flew out of BOS in November with AirTran. Everyone went thru the metal detector then the full body scanner (unless they opted out).

For my industry, there have been studies of the amount of radiation received during the security screening process and during the rest of the traveling experience. A person receives far more radiation on board a flight at cruise altitude (35,000 ft asl) than they do going through the scanners.

MYOB is not very nice. A poster offered an opinion contradictory to yours and you jump all over her. When she tries to "defend" herself you tell her to MYOB.
If you do not want unnecessary exposure perhaps you should't fly at all. I don't think anyone is arguing that we are exposed to radiation as we fly.

MYOB? Not everyone shares your opinion. This is an internet discussion board. People are entitled to express their opinion.

A couple of University professors would like further research. Probably wouldn't mind if they got funding to do the research.

Available evidence suggests the scanners are completely safe. More studies/research isn't a bad idea but.
