On Friday, March 18 17:36 JST (04:36 am Friday March 18) NHK reported that TEPCO reported radiation measurements about 500 meters northwest of the Fukushima Daiichi plant on Friday Mar 18 JST afternoon.
- 1:50 PM 3,484 μSv/hr
- 2:50 PM 3,339 μSv/hr
For a nuclear energy worker 15 hours of exposure to this level of radiation is equivalent to the annual permissable exposure of 50 mSv.
Interested in your calculations relative to OSHA standards. If I read the conversion correctly (1000 uSv = 1 REM) 15 hours of exposure @ 3,484 uSv would be equivalent to 52 rems.
As defined in OSHA 1910.1096, 52 rems is equivalent to max exposure:
a) whole head/eys/gonads would be 42 years worth
b) hands/arms or feet/ankles would be 2.79 years worh
c) whole skin would be 6.97 years worth.
could you help with your references and calculations please?
