Japan & Radioactive products!

After the tragic events that occurred this March in Japan and lead to the Fukushima Daiichi nuclear disaster, recent studies revealed that its now on a par with Chernobyl! A very large part of the country was covered with radioactive particles & radiation carried by the wind & water, the sea was contaminated with the radioactive waste from the power plants and even the Tokyo public water supplies were contaminated! As a result many local Japanese heavy industry factories like SONY, Canon, Toshiba, etc… ceased production and closed down and only restarted production recently.

It’s obvious that edible & biological goods, like fish, vegetables, meat, soya, noodles, etc… from Japan should be avoided, but what about other mechanical / electronic / paper, textiles & non-biological products made in Japan like TVs, digital Cameras, consoles, computers, cars, DVDs, comics, clothes, etc… or even older / used products like video games, books, DVDs, computer / console hardware, etc… that had been stocked in Japan?!
Shouldn’t all these also be considered dangerous for public health as their parts (or as a whole) could have been exposed to radiation and contaminated with radioactive particles that recently covered the entire country and surrounding area?!

For example how safe would it be to buy one of these, which is made in Japan:

I would really like to get some valid scientific answers concerning these queries and even get some valid scientific / encyclopaedia links that will clear up these matters.

Thanks in advance.
