So your expecting the radiation to penetrate and stay concealed within these products even though they go through radiation tests at customs to try and prevent any nuclear warfare.
Not only that, but your then expecting these products to posses enough radiation to expell it in high enough levels to affect someone (namely you)?
Your probably sat, reading this and breathing in more radiation particles from the earth than what would be given to you in computer products.
Penetrate?
Did you read my OP, or watch the enclosed video? You seem to be under a common misconception.
The radiation which threatens to contaminate (and already has in some cases) exports is the physical elements thrown out of the reactor(s). Elements such as Caesium, Strontium, Uranium and even Plutonium.
They're in the form of very small particles, and they were airborne in great quantities in March and April, and they're still being released now albeit in much lesser quantities.
It is these 'hot particles', which pose the greatest threat to our health. It is these particles which irradiate and will continue to do so for hundreds, and in the case of Plutonium, hundreds of thousands of years.
People need to stop thinking of radiation as simply the irradiating rays themselves, this is why any comparisons to X-rays and the like are nonsensical and intentionally misleading.
Think of these 'hot particles' as grains of sand. Well imagine billions of these grains of sand being fine enough to become airborne and fine enough to go unnoticed by the naked human eye. Grains of 'sand' that you can easily inhale or ingest. This is what the Japanese are dealing with, and in a much lesser extent us - when we consider the
possibility of a small, but nonetheless still harmful amount of these particles being present on an export we purchase unwittingly.
I seriously doubt our government is conducting stringent checks for such contamination, have you any idea how costly that would be? Much more economical to play down the risks and continue as if it's business as usual - which alarmingly it appears to be just that, for some businesses at least.
Besides, depending on what type of radiation these 'grains of sand' emit, should they be contained within a package they may be entirely impossible to detect without opening the said package - even with a geiger counter. And this is due to the varying strengths of the irradiating rays they release.
You can find the differences between the different types of emitters (Alpha, Beta and Gamma) here, explained in Layman's terms;

And to be frank, your last comment is entirely nonsense.
