Thanks for the link! The video is about the iPad 1. I currently only have an iPad 2 and 3 at home but will immediately check my iPad 1 tomorrow.


My iPad 2 and 3 (purchased in Finland) don't exhibit any kind of radiation. (Before you ask, I know quite a little bit about measuring radiation and I have the currently available best prosumer (read: priced at $300) G-M counter -the Soeks Ecotester.)


Will tomorrow post a video of all this (incl. measuring the iPad 1).

I've purchased my G-M counter, among other things, to correctly and reliably measure my gadgets (of which I have plenty), mostly assembled in China (and some in Japan, but before the nuclear accident last year). Not any of them show any kind of radiation. Heck, I've even measured Russian and Soviet-made old stuff like radios, N/S8/36mm film cameras.


That is, manufacturers don't use radiactive material by purpose, which is pretty much understandable: Uranium (or any kind of radioactive material) is very expensive and sought-after. Noone will just put uranium in their devices, cars, gadgets because it's "cheap". Just the opposite... this is why I haven't measured any kind of radiation with any Russian gadget, car I could gain access to. Used fuel stuff is another matter but rest assured: Russians or the Chinese don't get rid of their radioactive waste (more info on the subject: http://en.wikipedia.org/wiki/Radioactive_waste#Long_term_management_of_waste ) by purposely putting them in their devices.


It's possible this particular iPad has some radiactive residue because the screen was assembled in Japan just after the accident and just inside to the radiactive fallout zone. However, this is plain bad luck - I'd say at most the batch in the given day / week is effected.


What about the consequences? Well, your finger gets some (minimal) radiation while it's on (touching) the screen. The radiation level quickly degrades even one cm (0.4") apart. As is also demoed on the video, there's no radiation at all on the back side.


That is, if you're afraid of getting some radioactive dose and don't have a friend with a GM counter (which are very expensive - a usable, current, sensitive model with a decent display starts at $150. I recommend those of SOEKS: not that expensive (the most expensive model, the Ecotester, is sold for around $300 at eBay) but very good) to check your iPad, don't let your finger rest on the screen. That's all. You can safely hold the iPad on your lap as tehre won't be any radiation backwards.


But, again, it's the best to get a G-M counter (or visiting a friend with one) if you're afraid.

"There is a youtube video in which high radiation (gamma and beta if I remember right) is measured."


It's not gamma. Gamma would pass the back of the iPad too, not only the front. I'd say, based on this, it's alpha - just like the case with radium watches ( http://en.wikipedia.org/wiki/Radium#Historical_uses ).


Alpha particles aren't very dangerous (as opposed to beta and, even more, gamma). Even your skin provides decent defense against them. They're only lethal if you ingest the radium salts - as did radium girls. (See the above-linked article on them.)
