Compatibility with other data
Some other data indicate the level of radiation in $\mu$Sv/hour In order to compare, see http://en.wikipedia.org/wiki/Sievert ; according to wikipedia,

1 rem = 0.01Sv = 10 msV

As I understand, 1 mR/hr= 10$\mu$sV/hour ; id est, roughly, multiply the number with factor 10, and the result will be in $\mu$Sv/hour
