Abstract: The invention is directed to a system and a method for processing chemical substances, a computer program for controlling such system, and a corresponding computer-readable storage medium, which can be used, in particular, to flexibly adapt synthesis devices, in particular for radioactive chemicals or radioactive pharmaceutical products, to different process flows and to make the synthesis devices usable for research and routine operation. To this end, a system for processing chemical substances in a laboratory setting is proposed, wherein the system includes components for carrying out basic chemical processing operations. The components can be modularly combined according to presettable sequences of process steps for processing chemical substances and have matching modular dimensions. The components can also be implemented as stackable, self-supporting boxes.

Abstract: The present invention relates to highly radioactive, miniaturized, cylindrical strontium 90 titanate, strontium 90 zirconate, and strontium 90 silicate radiation sources having an activity exceeding 25 mCi/mm3, preferably ≧30 mCi/mm3, and a diameter less than 0.7 mm, preferably less than 0.4 mm. Another subject of this invention is a method for the production of these extremely small, but highly radioactive radiation sources.

Abstract: The present invention relates to new radioactive iodine-125 miniature radiation sources (seeds) comprising a radioactive carrier matrix which consists of a porous and mechanically stable inorganic material, the pores of which contain inorganic insoluble iodide-125, and which is enclosed within a capsule made of a corrosion-resistent and body-compatible material or which is coated with such a material. The iodine seeds according to the present invention further may contain (a) usual X-ray marker(s). Another object of the present invention are methods for manufacturing said novel iodine-125 seeds.

Abstract: A novel support material for radionuclides has a higher capacity for radioactive substances than previously known support materials. Miniaturized radioactive radiation sources made from the support material display an enhanced dose capacity. The support material is made by the mixing of a suitable solid support with a polysaccharide followed by malleabilization.

Abstract: The invention relates to radioactive ruthenium sources with a dosage rate of at least 1.5 Gy/min at a distance (water) of 2 mm, consisting of an activity carrier and an encapsulation of the carrier made of a material compatible with the human body. A multilayer system made of metals and/or alloys is galvanically applied on the carrier. At least two layers in said system are made of ruthenium 106 and inactive intermediate layers made of other metals or alloys are provided between the radioactive ruthenium layers. The activity carrier is encapsulated with a material compatible with the human body, for instance a metal or a plastic material. Encapsulation can be carried out by filing a capsule and subsequently sealing or galvanically depositing a top layer made, for instance of hard gold.
