A needle holder for use in a seed handling assembly that is made as a box-like open-sided metal frame having a bottom, a top and opposed side frame members with a pair of steel shielding plates enclosing the sides of the frame. The top frame member defines at least one row of holes for receiving elongated needles containing radioactive seeds. Feet are attached to opposite sides of the frame to enable the needle holder to be free standing. Lifting elements are attached to the frame to enable the needle holder to be picked up and moved while needles are held in the needle holder and for a person lifting and moving the needle holder to be shielded from radioactive seeds in a needle.
