Officials were worried this week, when they discovered a radiation hotspot in Tokyo, kicking off readings as high as 3.35 microsieverts per hour. (For context, a dental x-ray is about 5 microsieverts. This wasn't a massive amount of radiation, but it was concerning. The AP reports that readings of that level have been found in the Fukushima evacuation zone.)
The good news: This has nothing to do with Fukushima. It turned out to be an extremely localized hotspot, and officials found the real source nearby.
The bad news: The real source turned out to be something the AP is describing as "mystery bottles" stored under someone's house. No. Really.
So, I guess the takeaway to this story should be something like: Japanese officials find source of radiation hotspot, and are no longer worried that it's being caused by Fukushima. Instead, they are now worried about why somebody in Tokyo is storing bottles of a radioactive substance under a house.
