ABSTRACT:
A radioactive seed which discloses the orientation and the location of the seed when the seed is exposed to X-ray photography is provided. The seed contains multiple X-ray detectable markers which will disclose the orientation and the location of the seed when the seed is exposed to X-ray photography. The seed can also have a single marker which wraps around the external surface of the seed or wraps around a carrier body within the seed. The single marker will also disclose the orientation as well as the location of the seed.
