Accuracy in external dosimetry of ionizing radiation.
A new approach to defining and calculating accuracy and uncertainty in external dosimetry is described. It is more comprehensive and mathematically rigorous than other approaches currently in use, while at the same time being practical to implement. The type testing required to demonstrate the performance of a dosimeter is described, and an example of the calculation of accuracy and uncertainty is given. The paper concludes with some recommendations concerning performance testing and independent testing.
