Natural Radiation in the Geochemical Environment

  • Douglas G. Brookins


Natural radiation is primarily from U and Th and their radioactive daughters, and from K and Rb. In addition, there is minor radiation from 14C and such species as 147Sm, 176Lu, and 187Re. There is also a very small amount of radiation (less than 0.04 mrem/yr) from radioactive species formed by atmospheric testing of nuclear weapons. The radiation in rocks, however, is basically due to U, Th, actinide daughters of U and Th, and K and Rb. Only these sources will be discussed in this chapter.
