ABSTRACT
The computation of absorbed dose to organs and tissues in the human body following exposure to ionizing radiation requires a variety of data on the exposed individual. Anatomic data include items such as the height and weight of the exposed individual, the masses of individual internal organs, and the elemental composition of these organ tissues. Immediately following World War II, there was a tremendous expansion in the development of radioactive materials, radiation devices, and radiological systems for industry, commercial, and medical use. The Commission is aware of the uncertainty or lack of precision in radiation dose models and efforts are undertaken to critically evaluate and to reduce them wherever possible. For regulatory purposes, the dosimetric models and parameter values that the Commission recommends are reference values. Radiation epidemiological data suggest a significantly lower dose threshold for the induction of radiogenic cataracts.
