Understanding Valid vs Invalid Dose values
DoseControl uses the dosimeter batch Calibration coefficients as part of the dose calculation. The dosimeter batch calibration has a minimum and maximum dose range. Each dose point on the calibration curve that is within the calibration’s dose range is a valid dose.
Definition of valid vs invalid dose
A “valid” dose is one that is greater than or equal to the minimum dose of the Calibration and less than or equal to the maximum dose of the Calibration.
An “invalid” dose is one that is outside the Calibration range. This applies equally to "measured" and "adjusted" doses (adjusted dose is a measured dose multiplied by a linear correction factor stored in the calibration configuration record).
How dose the DoseControl dosimetry system calculate dose?
DoseControl follows these rules for handling dose values:
When a dosimeter's dose is VALID, the software displays/outputs the numerical value of dose (in the user interface and in outputs (i.e., Excel, PDF, Export Tables). A “valid” dose is one that is greater than or equal to the minimum dose of the Calibration and less than or equal to the maximum dose of the Calibration.
When a dosimeter's dose is INVALID, the software screen will display a graphical indication. An “invalid” dose is one that is outside the Calibration range. This applies equally to "measured" and "adjusted" doses (adjusted dose is a measured dose multiplied by a linear correction factor stored in the calibration configuration record).
