That's moderately hot. Double 21,000C/M @ 6" would be 17.5 mR/Hr at the
standard distance of 1 ft. I haven't kept up with standards since I got out
of the business but the unmonitored boundary around operations used to be
2mR/Hr. Which would be at a distance of just under 3 ft. from the Gibson Girl.
