This site – is reporting the daily radiation levels in Tokyo.

Today’s Tokyo average radiation level, while higher than the Tokyo average, averaged about 0.25 microsieverts/hr.
That’s 2.19 millisieverts per year, or just 73% of the background radiation of Boston.
In other words, the year-round natural background radiation of Boston is 37% higher than today’s higher-than-normal radiation level in Tokyo.

I’m staying here!
