Inclusion of time uncertainty in calibration of ionizing radiations

In terms of metrology, two key factors for reliability employed in the calibration process are what we call Traceability and Uncertainty. Traceability will provide confidence in measurements. Already uncertainty will provide security and quality of what this being measured. Based on the above, this article suggests the implementation time of uncertainty in the calibration of radiological instruments thus increasing the reliability and traceability of the system. (author)
