Each and every individual will have to make that decision for themselves, but they have to at least realize that the Japanese government and Tepco have admitted lying. So there is a track record of lies. And they also need to realize that any contamination they receive will be eventually brought back to their home countries.
And there is also a history of problems with communications within Tepco and Japan. Just recently the government run inquiry into the Fukushima crisis determined that Tepco did not ask to abandon Plant #1 and eventually possibly Plant #2.
Apparently the Japanese words and phrase used can be perceived as either:
- temporarily partially abandoning Fukushima #1 due to high radiaition levels and then returning later.
- possibly meaning abandon Fukushima #1 and possibly #2 permanently but in a slow staged process.
That is what you have to deal with over there.
