Return to footnote 1Excluding Auger electrons emitted from nuclei bound to DNA.
Return to footnote 2Radiation weighting factors for these neutrons may also be obtained by referring to the continuous curve shown in Figure 1, and Equation 4.3, on page 66 of the English version of The 2007 Recommendations of the International Commission on Radiological Protection, ICRP Publication 103, published in 2007.
