A solar collector apparatus includes a parabolic mirror configured to direct solar energy through a double convex lens and towards a linear set of secondary mirrors, each of the secondary mirrors positioned to direct the solar energy towards a solar collection target. The subsequent diversion achieved by the solar collector apparatus allows collection of solar energy several times denser than natural sunlight, and can be captured using a substantially compact system.

Methods and kits for incorporating a radioactive astatine isotope (particularly .sup.211 At) into an organic compound by electrophilic astatodestannylation of organostannanes.

Astatinated organic compounds

A process for reliably and consistently producing astatine-211 in small controlled volumes of a solution, which is selected from a choice of solvents that are useful in selected radiopharmaceutical procedures in which the At-211 activities are to be applied.

Process for producing astatine-211 for radiopharmaceutical use

A method for simultaneously preparing Radon-211, Astatine-211, Xenon-125, Xenon-123, Iodine-125 and Iodine-123 in a process that includes irradiating a fertile metal material then using a one-step chemical procedure to collect a first mixture of about equal amounts of Radon-211 and Xenon-125, and a separate second mixture of about equal amounts of Iodine-123 and Astatine-211.

Method for the simultaneous preparation of Radon-211, Xenon-125,

There is described an apparatus and method for diagnosing ocular cancer that is both non-invasive and accurate which comprises two radiation detectors positioned before each of the patient's eyes which will measure the radiation level produced in each eye after the administration of a tumor-localizing radiopharmaceutical such as gallium-67.

Method for non-invasive detection of ocular melanoma

An apparatus and method for injecting a substance, such as a radiopharmaceutical, into the bloodstream of a subject. The apparatus comprises an injection means, such as a servo controlled syringe, a means for measuring the concentration of that substance in the subject's bloodstream, and means for controlling the injection in response to the measurement so that the concentration of the substance follows a predetermined function of time. The apparatus of the subject invention functions to inject a substance into a subject's bloodstream at a rate controlled by an error signal proportional to the difference between the concentration of the substance in the subject's bloodstream and the predetermined function.

A method for the production of .sup.211 Rn comprising bombarding .sup.209 Bi with .sup.7 Li particles utilizing the nuclear reaction

Method for the preparation of radon-211

A solution of potassium-38 suitable for use as a radiopharmaceutical and a method for its production. Argon is irradiated with protons having energies above the threshold for the .sup.40 Ar(p,3n).sup.38 K reaction. The resulting potassium-38 is dissolved in a sterile water and any contaminating chlorine-38 is removed.

Process for preparation of potassium-38

.sup.203 Pb-tris complex injected for use in the detection and localization of tumors. The lead-203 is produced from the deuteron bombardment of a thallium target and chemically separated from the thallium. The tris is added which complexes with the lead-203.

Production of .sup.203 Pb-tris-hydroxymethyl amino methane

The method of labeling indocyanine green (ICG) with carrier-free iodine-123 comprising the steps of condensing xenon-123 on crystals of ICG followed by permitting decay of the .sup.123 Xe a sufficient length of time to produce .sup.123 I-electronically excited ions and atoms which subsequently label ICG.
