Note. Ambient dose equivalent (expressed in “Sieverts” (“Sv”)) characterizes the
influence of ionizing gamma radiation on the biological object (human), as opposed
to exposure dose (expressed in “Roentgens (“R”)”) that characterizes the capacity of
gamma radiation to ionize the air. Generally, to make it simple, use the coefficient
circa 100 to covert ambient dose equivalent units into exposure dose units:
1.0 μSv 100.0 μR.
Dose rate conversion, correspondingly: 1.0 μSv/h 100.0 μR /h.
Natural radiation background normally equals circa 0.1 μSv/h (10 μR /h).
