Abstract

Microscopic electron dose distributions inside and outside the colloid spheres of thyroid tissue of radii 15–150 µm containing 1.5 µCi/g¹²³I,¹²⁵I,¹³¹I, and¹³²I uniformly distributed have been calculated by the application of Berger's scaled absorbed dose functions approximated by standard polynomial regression techniques. For¹³¹I,¹²³I and¹³²I whose electron or effective beta energy ranges are at least few times more than the sphere sizes considered the contributions of energy emitted from neighbouring follicles have been included into the dose calculations. Additionally, the frequency mean and energy mean of microscopic event-size distributions in small spherical¹²⁵I sources have been computed in rad per one¹²⁵I disintegration.
