Regarding "Working Levels." - If there was ever a unit that needed to be SI'd, this is it. On the other hand, I think that most persons, other than those who earn a living from Rn testing and remediation, agree that this is a solution looking for a problem, EPA scare ads notwithstanding.

I think Bjorn gave us the best flavor of what it takes to get used to a system.The reason it's taking so long for the US to go metric is because the big push in the '70's (when I was in grade school) was such a flop. Instead of trying to give everyone a feel for the 'new' units, we were told, hey, look, an inch is 2.54 centimeters and a gallon is 3.7854 liters! No problem! Here's a table for you to memorize. Naturally, that made no sense to anyone. Plus, manufacturers objected to the real cost: retooling factories for metric sizes on nuts and bolts, etc.
Now, I have to think we've come a long way. Most people who use wrenches have already bought a metric set and maybe wish they wouldn't have to keep the english set too.
By the way, for radon measurements, is there anything metric that captures the real meaning of a working level?
