Abstract
A neutron source for neutron brachytherapy is disclosed that may generate neutrons to treat cancer and other tumors. The neutron source in accordance with the invention may include a capsule into which the neutron emitting material is loaded and a guide wire. A coiled wire may be placed around the capsule and the guide wire to strengthen the capsule and guide wire. In accordance with one embodiment, the capsule containing the neutron emitting material is sufficiently thin so that the helium gas generated during the decay of the neutron emitting material may escape into the atmosphere. In a preferred embodiment, the neutron emitting material may be Californium (Cf.sup.225).
