A new, improved method for estimating doses to body organs in the digestive system due to the passage of a solid radioactive particle through the digestive system. Normally, in this instance, doses to internal body organs are estimated (calculated) using mathematical models, because such doses cannot be measured routinely, if at all. Such models are used internationally as a basis for radiation protection standards. This new method applies to low penetrating emissions of a radionuclide, typically beta and/or alpha particles, low energy (soft) x-rays and/or gamma rays, and Auger electrons. The new method is physically correct in principle, in that it explicitly incorporates the location and velocity of a solid particle in the gastro-intestinal tract, whereas current and previously applied methods are incorrect, in this application. Moreover, this new method will provide estimates of the probability of dose, which is not considered in current methods of estimating such doses.
A method for calculating the probabilities of doses to body matter induced by low penetrating ionizing radiation emanating from radionuclides as said radionuclides are transported through the digestive system in a solid particle that is insoluble or partially soluble in body fluids, comprising the steps of:
