    摘要： A gamma radiation source comprising 75 Selenium or a precursor thereof, is disclosed wherein the 75 Selenium is provided in the form of one or more thermally stable compounds, alloys or mixtures with one or more nonmetals which upon irradiation do not produce products capable of sustained emission of radiation which would unacceptably interfere with the gamma radiation of 75 Selenium. A further gamma radiation source is disclosed comprises 75 Selenium or a precursor thereof, wherein the 75 Selenium is provided in the form of one or more thermally stable compounds, alloys or mixtures with one or more metals or nonmetals, the neutron irradiation of which does produce products capable of sustained emission of radiation which would acceptably complement the gamma radiation of 75 Selenium. Further, the gamma radiation source may have components that are separately irradiated before being combined and the components may be of natural isotopic composition or of isotopically modified composition so that the subsequent radiation peaks may also be adjusted in relative frequency.

    摘要： A capsule (1) for holding, irradiating, and eluting a material is provided. Methods of fabricating and using the capsule are also provided. The capsule may include a multidiameter tube (10) with a first end region, a second end region, and a middle region. Washers and filters are provided in the end regions and the end regions may be sealed using various methods and materials with the end caps press fit into the end regions. The middle region is designed to store a material to be irradiated by a neutron flux source. The capsule components may be made from materials having a low nuclear cross section so that the capsule may be handled safely after an irradiation step is performed. The capsule is also designed to have a symmetric configuration as an elution and irradiation column so that the same capsule may be used to elute the material within the middle region of the capsule after an irradiation step is performed.

    摘要： Gamma radiation imaging system for non-destructive inspection of the luggage contains a DR sub-system, which obtains the projected image of the luggage by translationally scanning, and a CT sub-system, which obtains the tomograph image of the luggage by rotating scanning. Said DR sub-system includes a fixed gantry, a conveyor system, a radiation source mounted on the fixed gantry, front and back collimators, and the array detector. Said CT sub-system includes a rotating gantry, a conveyor system, a radiation source mounted on the rotating gantry, front and back collimators, and the array detector, wherein, the radiation source in said CT sub-system is 192 Ir or 75 Se radioactive isotope gamma source with high specific activity. Said gamma source is enclosed in a shield chamber with a projecting opening. The shield chamber is mounted on said rotating gantry. Said array detector is adapted for detecting gamma ray of 192 Ir or 75 Se radioactive isotope; The radiation source in said DR sub-system is 192 Ir or 75 Se radioactive isotope gamma source with high specific activity, said gamma source is enclosed in a shield chamber with a projecting opening.
