A pellet for a radioactive seed, suitable for use in certain medical radiological treatments, including a metallic X-ray detectable marker rod such as tungsten coated with a radioactive-absorbing material, such as a polyamino acid, in a binder wherein a radioactive material is absorbed. Such pellets are encapsulated in a material such as titanium to form an effectively sealed radioactive seed which is useful in certain medical radiological treatments. |
