To provide patient shielding of non-treatment areas bordering a treatment zone of the patient during radiation therapy, a shield device may be located on the patient. The shield device has a plurality of interconnected and overlapping elements, e.g. in a scale maille arrangement, that forms a conformal sheet that can be laid over the shielded portion of the patient, e.g. over the contralateral breast during breast cancer treatment. The edge of the scale maille sheet is substantially configurable and can be made to conform to the field edge of the treatment zone on the patient.

A novel PET calibration phantom structure is disclosed that has reduced overall weight and reduced radiation shielding requirement while still enabling safe handling. Furthermore, when the phantom is not being used, the + radiation source can be turned off or removed from the phantom, thus, lowering the radiation exposure risk to those handling the phantom.

An enclosure for non-organic electronic components is provided which includes an inner cavity for housing non-organic electronic components and a neutron shielding barrier surrounding the inner cavity and the electronic components housed within the cavity. The barrier is formed from a neutron reflecting material in solid or powdered form and a neutron absorbing material in solid or powdered form. An optional structural support is provided in certain aspects of the enclosure design.

Fabricating structural components for a spent nuclear fuel container using the steps of forming cylindrical or rectangular channels to produce a structural component for a spent nuclear fuel container and applying a coating that includes tantalum-based material to the cylindrical or rectangular channels.

A magneto-rheological filter/reflector that controls the transmissivity of any form of electromagnetic or particulate radiation through the filter by varying discrete electromagnetic fields across a magneto-rheological fluid. In one embodiment, the filter/reflector controls the rate of the nuclear reaction within the core of a reactor without any moving parts.
