Abstract
Calculations of the radiation dose to the lens for 99mTcO4- in dacryoscintigraphy are developed in some detail. The results indicate that the absorbed dose to the germinal epithelium of the lens is 2.2 X 10(-5) to 1.4 X 10(-4) rad/microCi (5.9 x 10(-12) to 3.8 x 10(-11) Gy/Bq) 99mTcO4- under physiological conditions. With blockage of the lacrimal drainage apparatus, the dose to the lens could increase to 4 X 10(-3) rad/microCi (1 X 10(-9) Gy/Bq).Entities:
