Abstract Object This paper discussed annual equivalent dose to hands of workers in the production process of 99Tcm. Method The equivalent dose of hand caused by the production of 99Tcm was estimated with different protective sheath and working time. Result Based on 250 working days in a year, the equivalent dose of hand with the 3 mm lead protective sleeve was about 668.8 msv/a, and the equivalent dose of handwith the 2 mm tungsten alloy protective sleeve was about 392.7 msv/a; based on 100 working days in a year, the equivalent dose of hand with the 3 mm lead protective sleeve was about 267.3 msv/a, and the equivalent dose of hand with the 2 mm tungsten alloy protective sleeve was about 157.1 msv/a. Conclusion The radiation effect of the hand dose in the production of 99Tcm could not be ignored. The working time should be reasonably allocated or the protective effect should be improved to ensure that the annual equivalent dose to workers' hands is lower than the annual dose limit of 500mSv/a for limbs or skin in GB 18871—2002.
