A delivery system and method for radiation shielded brachytherapy has a drive assembly, and a plurality of shield assemblies, pivotally mounted to the drive assembly, each having a tubular body defining an outer surface and a bore longitudinally extending between opposite ends of the tubular body. Each of the shield assemblies has radiation shielding material extending about a circumferential portion of the tubular body and disposed between the outer surface and the cavity. An interlocking system is operatively mounted to the rotating assembly, and engages a group of the plurality of shield assemblies. The interlocking system is configured for transmitting a rotational input received from a driving mechanism to the group of shield assemblies, for synchronously rotating each shield assembly of the group about their respective longitudinal axis.

A method that produces high energy charged particles that may be used to destroy cancer cells contained in cancerous tissues. The device uses electronic neutron generators to produce neutrons with energies that have a high probability to interact with a therapeutic source comprised of a reactive material with an outer layer of a material having a high atomic number such as Platinum or Gold. The reaction produces high energy electrons, and in some cases other charged particles with relatively short half-lives, which can destroy the cancerous cells, without seriously damaging the surrounding healthy tissue.
