I am doing some reading on Radon and am having trouble understanding some of the math. Never was good at it, and it is becoming a major handicap with this project.
13.1 Bq m[-2] h[-1]
Does the above info read square meters or does it read 100ths of a meter? M 2 I can understand, I think, as meaning squared meters, but the use of a negative number is what throws me.
Am I wrong in thinking this value stands or 13.1 Bq per 100th of a meter per hour, or is it a tenth of an hour?
Thanks for any who take the time,
