Measurements were made of the concentration of radioactivity in the breast milk of a patient following a 2 mCi (74 MBq) 99Tcm-DTPA dynamic renal scan. The concentration of activity was 0.88 nCi-1 ml at 2.75 h after injection and it decreased exponentially with an effective halflife of 4.3 h. The potential radiation dose to a breast-fed infant was small enough to conclude that breast feeding need only be interrupted for 4 h after injection.
对一名患者在进行2毫居里（74兆贝可）99锝-二乙三胺五乙酸动态肾扫描后母乳中的放射性浓度进行了测量。注射后2.75小时，放射性活度浓度为0.88纳居里/毫升，且呈指数下降，有效半衰期为4.3小时。对母乳喂养婴儿的潜在辐射剂量足够小，因此可以得出结论，注射后仅需中断母乳喂养4小时。
