Folks,
This might interest you. It is an IEEE news item available to the public
(no membership or subscription required).

Earlier (in USMA:50023) I reported that the U.S. annual exposure limit
for occupational workers was 50 mSv (50 millisieverts). Apparently the
Japanese impose a lower limit of 20 mSv for such workers.

The latter article also provides some new data. Apparently, near the
reactors radiation levels ranged up to 400 mSv/h but are now down to
0.600 mSv/h (600 µSv/h). I presume they mean within the buildings and in
areas people might normally work, not out at the gates or outer fence.
