NCRP Report No. 160 Section 3 Pie Charts: 

• Fig. 8.2. Distribution of S or E_US for the major sources of exposure for 2006. The percent values have been rounded to the nearest 1 %. The total for S is 1,870,000 person-Sv and the total for E_US is 6.2 mSv, using a U.S. population of 300 million for 2006. The other background category consists of the external (space and terrestrial) and internal subcategories [see Table 8.1 for the values of S (person-sievert) and E_US (millisievert)].

• Fig. 3.19. Percent contribution of various sources of exposure to the annual E_Exp for ubiquitous background radiation (3.1 mSv) for 2006. The same percentages apply for S and E_US. The percent values have been rounded to the nearest 1 %, except those <1 % [see Table 3.14 for the values of E_Exp (millisievert)].
