20130163707Method for Producing Isotopes, in particular Method for Producing Radioisotopes by Means of Gamma-Beam Irradiation - A method is described for producing a radionuclide product B. A target is provided which includes an amount of a nuclide A. A gamma (γ) beam from Compton back-scattering of laser light from an electron beam irradiates the target and thereby transmutes at least a portion of the amount of the nuclide A into the product B. Providing the target includes selecting a nuclide A which is transmutable into product B by a gamma (γ) induced nuclear reaction.06-27-2013
20120140863METHODS OF DETECTION AND IDENTIFICATION OF CARBON- AND NITROGEN-CONTAINING MATERIALS - Methods for detecting and identifying carbon- and/or nitrogen-containing materials are disclosed. The methods may comprise detection of photo-nuclear reaction products of nitrogen and carbon to detect and identify the carbon- and/or nitrogen-containing materials.06-07-2012

20120155593Detecting forgery of Art, Bonds and Other Valuables by Neutron Activation and Method Thereof - Apparatus and method for detecting forgery by neutron activation of art objects or other valuables such as bonds, wills, etc. comprising of a device applying neutron irradiation to a reference spot sufficient to produce radiation including gamma rays; immediately thereafter, a device and method of the invention determines and records the rate of emission as a function of time that results from the application of the thermal neutron irradiation to the reference spot and produces ‘initial’ data thereof; at one or several selected subsequent intervals thereafter, the device and method determines and records the quantitative measures of the radiation emission in the gamma ranges of energy emanating from the reference spot taken at time intervals after activation and produces ‘subsequent’ data, and a device and method compares ‘initial’ data with ‘subsequent’ data.06-21-2012
20120281799Irradiation Device and Method for Preparing High Specific Activity Radioisotopes - Using the device and method of the present invention, high energy photons, or gamma radiation, impinge upon a target comprising a nanomaterial that includes a target isotope, resulting in the release of one or more neutrons from the target isotope. This neutron release creates an effect known as “kinematic recoil,” which results in a recoiling photo-produced radioisotope which is ejected from the nanomaterial and can be harvested in high specific activity.11-08-2012
20090196390RADIOISOTOPE PRODUCTION AND TREATMENT OF SOLUTION OF TARGET MATERIAL - The invention provides methods for the production of radioisotopes or for the treatment of nuclear waste. In methods of the invention, a solution of heavy water and target material including fissile material present in subcritical amounts is provided in a shielded irradiation vessel. Bremsstrahlung photons are introduced into the solution, and have an energy sufficient to generate photoneutrons by interacting with the nucleus of the deuterons present in the heavy water and the resulting photoneutrons in turn cause fission of the fissile material. The bremmssrrahlung photons can be generated with an electron beam and an x-ray converter. Devices of the invention can be small and generate radioisotopes on site, such as at medical facilities and industrial facilities. Solution can be recycled for continued use after recovery of products.08-06-2009
20090274257APPARATUS FOR GENERATING NUCLEAR REACTIONS - Subatomic particles enter an atom at room temperature when the atom is held in a sufficiently strong magnetic field involving exposure to low frequency electromagnetic energy. The result is the release of particles, the generation of new bodies, including isotopes, and/or the release of energy.11-05-2009

20120106691Method and System for Radioisotope Generation - A system and a process for producing selected isotopic daughter products from parent materials characterized by the steps of loading the parent material upon a sorbent having a functional group configured to selectively bind the parent material under designated conditions, generating the selected isotopic daughter products, and eluting said selected isotopic daughter products from the sorbent. In one embodiment, the process also includes the step of passing an eluent formed by the elution step through a second sorbent material that is configured to remove a preselected material from said eluent. In some applications a passage of the material through a third sorbent material after passage through the second sorbent material is also performed.05-03-2012
20120314827System for Active Long Range Detection and Identification of Special Nuclear Materials Using a High Intensity Particle Beam - A long-range method and a system for reliably detecting and identifying special nuclear materials is provided that relies on the emission of delayed neutrons present in the decay of fission products (delayed neutron precursors) as a unique signature for the special nuclear materials, such as highly enriched uranium (12-13-2012
20110286564ACCELERATOR DRIVEN POWER GENERATION - A redundant, low cost accelerator driven system for power generation or waste treatment. The system generates fission from fertile nuclear materials and includes multiple charged particle sources, nested redundancy of low energy accelerator sections for reliability, and multiple subcritical reactors. Merging and splitting devices based on radiofrequency transverse kickers enable the nested redundancy. A control system provides RF buckets with identifiers, enabling the control of charged particles on an RF bucket basis through the accelerator, for the delivery to a desired subcritical reactor of a desired number of RF buckets of such predetermined characteristics to generate a desired reactor power. Consequently, the power level of each reactor may be controlled independently even though a large part of the high power accelerator system is used to feed multiple reactors simultaneously.11-24-2011
