Measurement
reproducibility
Coefficient of variation of specific absorbance measurements on sets of dosimeters from
the batch, simultaneously irradiated together, in a radiation field uniform within +/- 1%,
is, over the entire calibrated range: |
not more than 2% 5 to
50 kGy |
not more than 2.5% 1 to 10 kGy at 603nm wavelength
10 to 30kGy at 651nm wavelength |
not more than 3% 100 to 3000Gy |
|
Calibration quality
Over the calibrated range, all mean specific absorbance data
points are within 3% of a fourth order polynomial least squares fit to the data. |
