摘要 |
A radiotherapy method, comprising positioning a predetermined amount of a radionuclide selected from the group consisting of Radium-223, Radium-224, Radon-219 and Radon-220, in proximity to and/or within a tumor of a subject, for a predetermined time period. The predetermined amount and the predetermined time period are selected sufficient for the radionuclide to administering a predetermined therapeutic dose of decay chain nuclei and alpha particles into the tumor. |

1. A radiotherapy device, comprising:
a removable probe, adapted for being at least partially introduced into a body of a subject and comprising at least one object selected from the group consisting of a needle, a tip of an endoscope, a tip of a laparoscope and a tip of an imaging device; and a radionuclide selected from the group consisting of Radium-223 and Radium-224, said radionuclide being retainably embedded on or beneath a surface of said object, said embedding ensuring that said radionuclide remains in said probe while a therapeutic dose of decay chain nuclei and alpha particles of said radionuclide is emitted outside said surface; said probe being coated by a protective coat, wherein a thickness and a material of said protective coat is selected so as not to prevent said emission of said decay chain nuclei and said alpha particles. |
