Abstract
A nuclear medical drug for localize radiotheraphy of a tumor and methods for its preparation. The drug includes a radioactive ceramic or glass particle having biocompatiblity. Ceramic or glass particles prepared by traditional processes become radioactive particles with pure .beta.-particle-emitting radionuclides after being irradiated with an appropriate flux of neutrons. The radioactive particle with suitable particle size can then be dispersed into a contrast medium for injection or can be implanted by operation.
Claims18
A beta-emitting radioactive phosphate ceramic or phosphate glass particle, comprising bio-compatible crystalline calcium phosphate wherein the particle has a high efficiency of neutron activation with an appropriate half-life, and enough radiation strength to kill the tumor or cancer.
