Innocence
I was surprised to learn that people live in Tokyo already inhaled thousands times of radioactive materials than Chernobyl on March 15 without knowing it. The level of Cesium-137 was130Bq/㎥ in Tokyo on that day. He said that iInternal exposure is much more dangerous than external exposure but not many people aware of it. Assistant professor of Kyoto University talked about it in his lecture on April 29. If we were notified by the government immediately after the exploxion at Fukushima nuke plant, we could have avoided the internal exposure.
