Uncertainties in the absorbed dose rate measurements.

Source Estimated uncertainty (%)
Statistical (degrees of freedom) si(vj) Other uj
Reproducibility of water 0.2 (8)
Sensitivity of C-thermistor 0.1 (3) 0.1
Sensitivity of J-thermistor 0.1 (3) 0.1
Effect of lead resistances 0.05
Beam attenuation of calorimeter lid 0.05 (5)
