Current average background radiation indoors in Tokyo is approximately 0.08microSieverts/Hour making this dust 25 times more radioactive than normal.

Is it Cesium 137?

Have returned to the same spot today to collect some dirt samples from the drain. Will be trying to figure out what this stuff is. Need to monitor rate of decay to figure out half life and possibly identify radiation type.

The sample taken on April 30 is still sitting on Allans desk ticking away, no evidence of decay so unlikely its Iodine 131, could be Cesium 137 or Strontium 90 or ????
