With the announcement Saturday in Buenos Aires of the winning bid for the 2020 Olympics, the Tokyo Metropolitan Government is running an English website dedicated to radiation-related information — a last-ditch effort to brush off the negative impact from the contaminated water problems plaguing the crippled Fukushima No. 1 nuclear plant.

The website — monitoring.tokyo-eiken.go.jp/en/index.html — provides hourly radiation levels monitored at eight locations in Tokyo, including Shinjuku, Ota and Adachi wards, as well as the results of fallout, tap water and food sampling tests conducted by the metro government. The website also provides all of the past radiation readings Tokyo has monitored since 2011.

Visitors to the site, which was launched Friday afternoon, had topped 4,660 as of noon Wednesday, a metro official said. The figure is more than double the number an English website providing hourly radiation levels in Shinjuku received in a single month.
