What should I do to remove the transponder, which is almost invisible on an x-ray?
If you have something inside your body that is almost invisible on an x-ray, then it is not an RFID transponder. An implantable transponder has a copper metal coil antenna, which would show up quite clearly on any x-ray. Metal is denser than bone, so it would show up more brightly than your skeleton. If you have ever seen an x-ray of a broken bone with screws in it, you know what I am talking about.
