摘要：

Calculations of the radiation dose to thelens 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/μCi (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/μCi (1 x 10-9 Gy/Bq).
