Memory sticks......

I carry both SD cards and USB memory, as well as external USB hard drives, and never taken precautions, or had a problem with airport security in any way.

Note on Australia post website it states that items going to Washington will be "irradiated" and this will destroy electronic devices.

This might only apply to mail though.

I have taken cards and laptop some years back, they would have gone through scanners at each airport along the way and they work fine, still do after all those years.

AS for those naked body scanners in the US, they work similar to an X- ray, so

Mail Security

The United States Postal Service has advised that, owing to heightened security, longer delivery times are likely for articles addressed to US government agencies. This applies in particular to Washington DC five-digit zip codes ranging from 202xx - 205xx.

Mail may be subject to irradiation treatment prior to delivery. The irradiation process is safe***, but the US Postal Service is advising mail users that particular commodities may be affected:

• Any biological sample e.g. blood samples, could be rendered useless***

• Diagnostic kits e.g. to monitor blood sugar levels, may be adversely affected

• Photographic film will be fully exposed

• Food will be adversely affected***

• Drugs and medicines could have their efficacy affected

• Eyeglasses and contact lenses could be adversely affected

• Electronic devices would probably be rendered inoperable***

The US Postal Service advises that each irradiated mail article will bear an official notification to the addressee that the item was subjected to an irradiation process.

More interesting than that is that a few years back there was talk of irradiating our food and look at what it says there about what irradiation does to food.

Sounds like the mail is being "irradiated" rather than scanner/inspected. Wonder if it will glow in the dark afterwards (that probably only happens if Homer does the irradiating.....)

That's what you get when you use Australia Post as an Electronics Engineering Advisory Service.

They barely know about post, what makes you think they can handle this?

As it turns out, the irradiation is to kill bugs, and it won't kill electronics. If you wrap it in foil, they'll either crank up the dosage to make up for it, or, dismantle it and expose it anyway.

This has been going on for some time too. And, shock horror hold on to your knickers, not only to Washington State.

As have I and many, many others.

Backscatter xray uses xrays to *reflect* off one side of the subject while medical xrays go *through* the subject to look at the innards.

Backscatter is not blocked by things like clothes and such (though their resistance is visible), but IS blocked by the skin, and other things like pistols, rocket launchers and such.

The dosage of backscatter is by far lower than medical use xray too.

However, since this is ionising radiation, it does have a carcinogenic effect. From here, it depends on who you listen to. Some say *any* amount is too much, others say under the circumstances for the gain, the exposure is negligible. Both sides however quite happily bid their farewells on your flight, and both neglect to mention the radiation you're exposed to by the sun, now that you're on a long haul flight, and have less atmosphere stopping said radiation.

Ahh, the irony.

Not lost apparently on the tour guides that run to Chernobyl nowadays. You get your very own radiation dose tag, and are also alerted to the fact the flight you took to get there, had probably exposed you to more radiation than you'll get in Chernobyl.

ay, so

The fact that some of the images show the bones in the fingers, similar to a medical x ray is a bit of a concern

agree :) I would have said "kate's bush" though :)

all preservation methods effect the taste and nutritional value of the food.

IIRC the mythbusters didn't like the flavour of their irradiated corn chips.

"I had seen it on the Internet, so it must be true".

That's not backscatter xray. That's not how it works.

It's like me showing you a photograph of a Formula 1 race vehicle, and saying it's me driving.

That's either Hollywood fantasy, psychotic hallucinations, paranoid delusions or just plain crazy. Or all of the above, you never know, hey, I'm not judging...

More classic US reactionary policy.

Oh joy: Quote: "Are there changes to the mail after it has been irradiated? Yes. Irradiating mail at such high intensity creates new compounds, which can result in a different look, feel, and even smell. The potential health effects of these changes is unknown."

and

Quote: "Have people complained of health problems from irradiated mail? Some postal and federal workers have complained of skin irritation and respiratory problems associated with exposure to irradiated mail. However, there are no established health effects from the mail, and investigations into a these complaints are ongoing."

Dave.

Can affect eyeglasses? What are they doing, dropping them into a reactor core?

Radiation makes glass go a wonderful swirl of colours, I saw some drinking glasses at the atomic reactor at lucas heights that they put in the tank with the uranium and they came out very pretty.

Don't put them in your back pocket 'cause you might sit on them.

Good one. I keep them in the camera case on a tether with a card holder................................
