How to Monitor Radiation Levels in Tokyo on a Daily Basis

It’s been tough these past few weeks in Tokyo. While dealing with aftershocks and citywide power reduction, I have to deal with threats of radiation in the air, water and food.

And so here I am, still trying to grasp the concept of “microsieverts per hour“, here comes “becquerels per kilogram” begging for my attention. That’s quite a lot to handle.

With all those things going on, many agencies are collecting data on a daily basis. Trust me, that’s a helluva lot of data that I have to keep track of.

Lucky for me there are people who have gathered all the numbers and made them simple and easy to understand.

So for those of you who are looking for an easy way to find out about the latest radiation levels in Tokyo, you have come to the right place.

The graphs below show radiation levels in Tokyo, including how much Iodine-131 are still in the water supply.

As you can see from these graphs, the trend is going downward. Is that awesome or what? 🙂

Although the source data is provided by the Tokyo Metropolitan Institute of Public Health, I did not make these graphs. Please understand that I am not liable for any errors in the graphs you see here. Thank you.
