Embodiment Construction

[0021] The present inventions will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the inventions are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. As used in the specification and the appended claims, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise.

[0022] Referring now to the drawings, an irradiation target 100 according to the present invention includes a plurality of thin plates 110 slidably received on a central tube 120, as figure 1 and 2A To 2C best shown. Preferably, both the plurality of sheets 110 and the central tube 120 are formed from the same material that is capable of producing the isotope molybdenum-99 (Mo-99) after...

Abstract

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 leastone plate so that the at least one plate is retained thereon, wherein the at least one plate and the elongated central member are both formed of materials that produce molybdenum-99 (Mo-99) by way ofneutron capture.

Description

technical field [0001] The presently disclosed invention relates generally to titanium molybdate-99 materials suitable for use in technetium-99m generators (Mo-99 / Tc-99m generators), and more particularly to the production of those titanium molybdate-99 materials. irradiated target. Background technique [0002] Technetium-99m (Tc-99m) is the most commonly used radioisotope in nuclear medicine, such as medical diagnostic imaging. Tc-99m (m is metastable) is typically injected into a patient and, when used with certain devices, is used to image the patient's internal organs. However, the half-life of Tc-99m is only six (6) hours. Accordingly, a readily available source of Tc-99m is of particular interest and / or need, at least in the field of nuclear medicine. [0003] Given the short half-life of Tc-99m, Tc-99m is usually obtained by Mo-99 / Tc-99m generators where and / or when needed (eg, in pharmacies, hospitals, etc.). The Mo-99 / Tc-99m generator is a device for extracting...
