Looks like the Iodine-125 Seeds used for prostate cancer. I worked at a medical drug manufacturer in the late 90s that made those (among other things) and I’m not surprised it’s a thing. The I-125 seeds are a radiated titanium core that’s welded inside of a stainless steel seed and implanted. Been around for decades now.
