Abstract: A radiation source device. The radiation source device has a radiolucent window portion, such as formed of beryllium, with a front window and a sleeve portion having an outer surface and a window portion cavity therein. A primary element, e.g., a metal wire, is provided that has a radioactive end, which primary element is received in the window portion cavity with its radioactive end adjacent to the front window and a seal is located between an outer wall of the primary element and an inner wall of the window portion. A radiopaque capsule is provided and has an open end that is sized to receive the sleeve portion of the radiolucent window portion and the primary element. A secondary seal between the capsule and the radiolucent window portion is provided.

Abstract: A flexible radiation source. The flexible radiation source has a layer of flexible material with at least one radionuclide dispersed therein to form a flexible, radioactive matrix. A layer of flexible nonradioactive material is also provided to which the flexible, radioactive matrix is permanently attached. The flexible radiation source can be folded or rolled from an extended or planar configuration to a folded or rolled configuration without causing the at least one radionuclide from becoming separated therefrom. The flexible matrix material is free from encapsulation by any rigid structure when in use. A storage and shielding container with a compact form factor is provided. The form factor of the storage and shielding container accommodates the flexible radiation source when the flexible radiation source is in its rolled or folded configuration, but does not accommodate the flexible radiation source when it is in fully extended or planar configuration.
