Abstract
Since Mo-99 has a short half-life and the number of production sites are limited, it is desirable to minimize the amount of time needed to reduce the irradiated Mo-99 material to a useable form. An irradiation target for the production of radioisotopes comprising a plate defining a central opening. The irradiation target also comprises an elongated central member passing through the central opening of the plate so that the plate is retained on the central member. The elongated central member includes an annular groove formed in an outer surface in a middle portion of the elongated central member. The elongated central member is configured to break at the annular groove into two portions when sufficient force is applied transversely to the elongated central member. The plate and the elongated central member are both formed of materials that produce molybdenum-99 (Mo-99) by way of neutron capture.
Claims (9)
1. An irradiation target for the production of radioisotopes, comprising: at least one plate defining a central opening; and an elongated central member passing through the central opening of the at least one plate so that the at least one plate is retained thereon, the elongated central member including an annular groove formed in an outer surface thereof of a middle portion of the elongated central member so that the elongated central member is configured to break at the annular groove into a first portion and a second portion when sufficient force is applied transversely to the elongated central member, wherein the at least one plate and the elongated central member are both formed of materials that produce molybdenum-99 (Mo-99) by way of neutron capture.
2. An irradiation target of claim 1, wherein: the at least one plate further comprises a plurality of plates, each central opening of each plate being a circular aperture, and the elongated central member is a cylindrical central tube, the cylindrical tube extending through the plurality of plates.
3. An irradiation target of claim 2, wherein the central tube has a first end and a second end that each extend axially outwardly beyond a respective end of the plurality of plates, wherein the first end and the second end each have an outer diameter that is greater than a diameter of the central openings of the plurality of plates.
4. An irradiation target of claim 3, wherein each plate is an annular disk and the plurality of annular disks and the central tube are formed from molybdenum-98 (Mo-98). 20578188_1 (GHMatters) P111888.NZ
5. An irradiation target of claim 4, wherein each annular disk has a thickness in an axial direction that is parallel to a longitudinal center axis of the central tube of approximately 0.005 inches.
6. An irradiation target of claim 5, wherein each annular disk has an outer diameter of approximately 0.50 inches.
7. An irradiation target of claim 3, wherein each plate is an annular disk and the plurality of annular disks and the central tube are formed from one of Molybdenum Lanthanum (Mo-La), Titanium Zirconium Molybdenum (Ti-Zr-Mo), Molybdenum Hafnium Carbide (Mo Hf-C), Molybdenum Tungsten (Mo-W), Nickel Cobalt Chromium Molybdenum (Mo-MP35N), and Uranium Molybdenum (U-Mo).
8. An irradiation target of claim 1, wherein: the at least one plate further comprises a plurality of plates, each central opening of each plate being an elongated slot, and the elongated central member is an elongated strap, the elongated strap extending through the central openings of the plurality of plates.
9. An irradiation target of claim 8, wherein each plate is an annular disk and the plurality of annular disks and the elongated strap formed from molybdenum-98 (Mo-98). 20578188_1 (GHMatters) P111888.NZ
