| 20120002774 | METHOD FOR DETERMINING INTENSITY OF GAMMA RADIATION EMISSION OF A RADIOELEMENT - A method for determining the intensity I(Ech | 01-05-2012 |
| 20120140863 | METHODS 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 |
| 20120155593 | Detecting 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 |
| 20120281799 | Irradiation 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 |
| 20130163707 | Method 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 |
| 20140098918 | Method and System for Detecting Special Nuclear Materials - A method and system for detecting special nuclear materials are disclosed. Said method and system detect the special nuclear materials by making use of the photofission characteristic and thermal neutron induced fission characteristic thereof. In one preferred embodiment, the high density and/or high atomic number region in the object to be detected is also detected first as a suspicious region. | 04-10-2014 |
| 20140321589 | NON-INTRUSIVE METHOD TO IDENTIFY PRESENCE OF NUCLEAR MATERIALS USING ENERGETIC PROMPT NEUTRONS FROM PHOTON-INDUCED FISSION - Methods and systems for non-intrusively detecting the existence of fissile materials in a container via the measurement of energetic prompt neutrons are disclosed. The methods and systems use the unique nature of the prompt neutron energy spectrum from photo-fission arising from the emission of neutrons from almost fully accelerated fragments to unambiguously identify fissile material. The angular distribution of the prompt neutrons from photo-fission and the energy distribution correlated to neutron angle relative to the photon beam are used to distinguish odd-even from even-even nuclei undergoing photo-fission. The independence of the neutron yield curve (yield as a function of electron beam energy or photon energy) on neutron energy also is also used to distinguish photo-fission from other processes such as (γ, n). Different beam geometries are used to detect localized samples of fissile material and also fissile materials dispersed as small fragments or thin sheets over broad regions. These signals from photo-fission are unique and allow the detection of any material in the actinide region of the nuclear periodic table. | 10-30-2014 |
| 20150318065 | DEVICE FOR CONVERTING RADIATION ENERGY TO ELECTRICAL ENERGY - The present disclosure relates to a device for conversion of one type of energy into another type of energy. Specifically, the device converts radiation energy into electrical energy. | 11-05-2015 |
