Radiation Readings around my Home!

Kashiwa City purchased 1,500 Geiger counters 2 months ago and announced that they would come to your home and make their readings, if you applied.

Of course, I applied. They told me at the time that it would not be possible to come till the new year, but they came today, December 13, 2011! Two very nice young men. The readings are done at two levels, touching the ground (0 meters) and at 1 meter.

Here are the readings in micro sieverts per hour:

Main rain Drain at 1 meter 0.22
         at 0 meters 0.37

Middle of Deck at 1 meter 0.20
         at 0 meters 0.39

On the ground in front of the deck at 1 meter 0.25
         at 0 meters 0.45

Under the large plum tree at 1 meter 0.25
         at 0 meters 0.44

Our Living room at 1 meter 0.125
         at 0 meters 0.095

Our Bed room at 1 meter 0.145
         at 0 meters 0.13

2nd floor veranda near rain drain at 1 meter 0.166
         at 0 meters 0.171

Front door area at 1 meter 0.15
         at 0 meters 0.15

Garage at 0 meters 0.010

Ground near front door at 0 meters 0.010

Basically, they said our area was low in radiation compared to other places.
I believe they said that staying outdoors at a 0.25 micro sievert level for 8 hours and then going inside would result in a 1 milli sievert level of radiation. This is considered safe.
