[en] New approaches in the production of longer-lived radionuclides have occurred, and in the ten last years some excellent progress reports have been updated and published. Because of the growing number of data, however, it becomes more and more difficult to present general overviews, consequently the trends is towards specialization. (author) 18 refs
[en] A transverse radionuclide scan field imaging apparatus is claimed. It comprises: a plurality of highly focused closely laterally adjacent collimators arranged inwardly focused in an array which surrounds a scan field, each collimator being moveable relative to its adjacent collimator; means for rotating the array about the scan field and means for imparting travel to the collimators
[en] Device for eluting nuclide generators comprising a nuclide generator, conveying means, container for eluting agent, and eluate container is described. The container for the eluting agent, the eluate container and the conveying means are connected with the nuclide generator by conduits, the conveying means are mounted between the container for the eluting agent and the eluate container and the conveying means comprise a control mechanism, which permits to convey freely chosen amounts of eluate into the eluate container.

[en] An historical review of the technologies for electricity generation using the decay heat of the radioisotopes is done. The technologies to convert the heat into electricity in the RTG (Radioisotopes Thermal Generators) Systems are described. The past, todays and future applications of RTG are described, to provide electricity to equipment in spatial satellites and spacecraft, lighthouse tower and sea bouys, submarine rovers, etc. At the end the safety characteristics and international regulations for RTG are mentioned.
