Dosimetric evaluation of individuals to U series, Th series and K radionuclides present in Brazilian ornamental rocks using computational simulation.

Granites are widely used in construction and they may be potential sources of ionizing radiation, due to the presence of radionuclides such as Kand decay products from Useries and Thseries. These radionuclides occur in the minerals constituting the rocks. To evaluate the doses in humans exposed to K, and decay products from Useries and Thseries γ radiation, a room with dimensions of 4.
