"50 millirems/"

"Reading in one location was about 4 Rems/Hour. At the site gate readings have dropped from slightly above 1 Rem/hour at 9:30 am (Tokyo time) to about 50 millirems/hour at 3:30 pm (Tokyo time)."

The plural of rem is rem not rems. Millirem not millirems. Rem is a measurement of biological destruction not a measure of radiation. That would be rads. How much of this stuff can you believe? Sitting there keeping track of every little new tidbit about this disaster seems to me to be highly unproductive and morbidly paranoid. It happened, folks, get over it. Sitting there biting your nails doesn't improve the situation. Get on with your lives. Or at least find lives to get on with.
