Despite the holocaust by the government, Japanese citizens are still trying to save their younger generation.
On 12/7/2011, they made a map of urine test result.
Parents can have their children take urine test and post it on the map, so you can compare where is more risky or not in terms of internal exposure.
There are some questions such as “I took care about food for children so much but the result was not good as I expected.” etc..
In order to find a hint for those questions, there is a details list on the site too.
Because it’s a new site, not so much data are uploaded but I personally find it a great attempt.
