The combined standard uncertainty for a dose or dose rate measurement is calculated according
to the method described in IEC 61674:2012, annex A. The calculation considers, among others,
the influence quantities repeatability, radiation quality, direction of incident radiation, pressure and
temperature and is based on the calibration uncertainty of the RaySafe calibration lab as well as
data from PTB type testing. The combined uncertainty is less than 5 %.
R/F SENSOR: MEASUREMENT PARAMETER DEFINITIONS
Dose and HVL are calculated from all recorded data.
Dose rate is the average dose rate, calculated as dose/time.
Time starts the first time the dose rate waveform reaches 50% of peak, and ends the last time it
drops below 50%. Live readings are time since start trig.
kVp and total filtration are calculated from an average of samples above 90 % of peak signal
level.
Pulses are counted at every start trig with more than 4 ms since last end trig. With AC pulse
counting set to On, pulses are counted each time the dose rate waveform rises above 50 % of
peak.
Pulse rate and dose per pulse are moving averages.
For measurements longer than 3 s, the final readings of dose rate, kVp, HVL and total fil-
tration are moving averages ending approximately 1–2 s before end trig. Live readings are moving
averages.
