Ionizing radiation
Geographical location
In the CMCs uncertainty statements, the notation Q[a, b] stands for the root-sum-square of the terms between brackets: Q[a, b] = [a 2 + b 2]1/2
Unless otherwise stated the expanded uncertainties given below correspond to k = 2 (at a 95 % level of confidence)
