Roppongi radiation

April 28, 2011 in Uncategorized

This time Allan is in Roppongi, Tokyo. The following video shows the level of radiation on the pavement on the streets of Roppongi. This video was taken at 8:30am on April 28, 2011 and indicates 75microRads/Hr (0.75microSv/Hr). Again the pavements seem to accumulate radiation from rainfall.

  1. I live close by at Azabu Juban and walk by that Azabu crossing frequently. Can you redo the test after it rains and see if readings increase or decrease and perhaps revisit the same spot one month later? If its Cesium it could be there for 30 years!
