A chelator having the general structure (I) for chelating radiometals such as 225Ac under mild conditions is provided. (I) The chelator can be coupled to a biological targeting moiety to facilitate targeted delivery of the chelated radiometal in a mammalian subject.
The present invention relates to methods for recovering a parent radionuclide from a radionuclide generator. In particular, the methods of the invention relate to recovering germanium-68 from a germanium-68/gallium-68 generator.

Abstract
A method of separating actinium and/or radium from proton-irradiated thorium metal. The thorium metal is irradiated to produce isotopes including thorium, actinium and/or radium. The resultant product is dissolved in solution and a selective precipitant is used to precipitate a bulk portion of the thorium. The precipitated thorium can be recovered. Chromatography is carried out on the remaining solution to remove residual thorium and to separate the actinium from the radium.

TARGET SYSTEM FOR IRRADIATION OF MOLYBDENUM WITH PARTICLE BEAMS
A target system for irradiation of molybdenum with charged particles from an accelerator to produce technetium and molybdenum radioisotopes. The target system comprises a molybdenum-100 material brazed with a brazing alloy to a backing material. The backing material preferably comprises a dispersion-strengthened copper composite. The brazing alloy comprises copper and phosphorus.
A process for producing technetium-99m from a molybdenum-100 metal powder, comprising the steps of: (i) irradiating in a substantially oxygen-free environment, a hardened sintered target plate coated with a Mo-100 metal, with protons produced by a cyclotron; (ii) dissolving molybdenum ions and technetium ions from the irradiated target plate with an H2O2 solution to form an oxide solution; (iv) raising the pH of the oxide solution to about 14; (v) flowing the pH-adjusted oxide solution through a resin column to immobilize K[TcO4] ions thereon and to elute K2[MoO4] ions therefrom; (vi) eluting the bound K[TcO4] ions from the resin column; (vii) flowing the eluted K[TcO4] ions through an alumina column to immobilize K[TcO4] ions thereon; (viii) washing the immobilized K[TcO4] ions with water; (ix) eluting the immobilized K[TcO4] ions with a saline solution; and (x) recovering the eluted Na[TcO4] ions.

Abstract
A method of mass spectroscopy according to example embodiments may include injecting ions into a Penning trap and exciting the ions into cyclotron and/or magnetron motions. The cyclotron motions and magnetron motions may be converted to one another with external radio frequency signals. The ions may be ejected from the Penning trap onto a position sensitive charged particle detector to determine the phases and amplitudes of the motions. Ion cyclotron resonance frequencies may be determined based on the phases and amplitudes of the motions of the ejected ions.
