Mean effective dose in workers estimated from OSL dosimeters

Specialty	Mean time (seconds)	Mean Hp(10) in worker X (mSv/proc.)	Mean Hp(10) in worker Y (mSv/proc.)
Orthopedics	529	0.26	0.11
Neurology	120	0.06	0.02
Urology	582	0.30	0.12
Vascular surgery	900	0.45	0.18

Standard deviations were all lower than 0.01.

Hp(10) = personal dose equivalent; proc. = procedure; OSL = optically stimulated luminescence.
