Radiation exposure due to 99mTc and 131I manipulated in syringes.
Dose rates around and at the surface of disposable polypropylene syringes of 1 and 2 ml volume filled with 99mTc and 131I solutions were determined by thermoluminescence dosimetry. Data for the efficacy of 0.5 and 1 mm lead shielding of 99mTc and for the dose contribution due to beta- -radiation from 131I are given.
