at a car exporter in Kawasaki City, in Kanagawa Prefecture.
At least, used cars for export get tested for radiation. And those cars rejected for export for high radiation? Where will they go? (Anecdotal evidence suggests they are simply sold inside Japan.)
From Sankei Shinbun (10/17/2011):
Kawasaki City announced on October 17 that a used car brought in to a used car exporter in Higashi Ogijima in Kawasaki-ku, Kawasaki City tested 20.38 microsieverts/hr radiation. According to the city, "That level of radiation does not have immediate effect on human body."
According to the city, the car was auctioned off in Chiba, and brought to the exporter in Kawasaki City for export. The license plate number was previously that of Iwaki City in Fukushima Prefecture. The car was destined for Kenya, but instead the dealer who had won the car in the auction took it back.
The city requires the dealers to report if any used car brought to the port of Kawasaki [for export] exceeds 5 microsieverts/hour radiation.
Let's see. 20 microsieverts/hour, and if you are on the road 2 hours a day for one year you would get 14.6 millisieverts external radiation from the car alone. Since it is less than 20 millisieverts, that's nothing in the current Japan.
The residents who lived within the 20-kilometer radius from Fukushima I Nuke Plant have been returning to their homes to retrieve cars and other items from their homes. Movement of cars in and out of Fukushima Prefecture is not restricted, except for the 20-kilometer radius residents whose cars need to be checked for radiation at J-Village. Many cars out of Fukushima, even those within the 20-kilometer radius area, have been transported by land to various locations in Japan. Only when the cars are sold to the exporters, then they are tested for radiation.
