SETTING: UNITS

Select displayed unit for dose and dose rate.
Air kerma, K

air

, is measured in Gy or R, where 1 Gy = 114.1 R.

Ambient dose equivalent, H

(10), is measured in Sv.

Typical response:

NOTE!

X2 systems approved by PTB do not have the possibility to change dose unit to Röntgen

(R).
