We performed glow-like discharge experiments using deuterated palladium cathode in deuterium atmosphere to investigate the possibility of inducing low-energy nuclear reaction. Anomalous gamma ray emissions in the 80 230keV region were sometimes observed. It was assumed that a nuclear reaction took place during the experiment, producing short-lived radioisotopes, and these radioisotopes emitted ...

The field of conventional energy conversion using radioisotopes has almost exclusively focused on solid-state materials. Herein, we demonstrate that liquids can be an excellent media for effective energy conversion from radioisotopes. We also show that free radicals in liquid, which are continuously generated by beta radiation, can be utilized for electrical energy generation. Under beta radiat...

Experts from 15 countries met at a symposium in Bangkok from 12 16 December 1960 to exchange information and ideas on the use of radioisotopes in the study of endemic and tropical diseases. Discussions at the meeting, which was sponsored jointly by the International Atomic Energy Agency and the World Health Organization, showed that radioisotopes had enabled medical scientists to gain a better ...

T concentrations of some of the elements in normal human enamel and dentine that give rise to short-lived radioisotopes, Ca, Na, Al, Mg and Cl, were determined by means of instrumen­ tal activation analysis and the results reported in a previous paper (Retief et al, 1970). Subsequently the concentrations of some of the elements that give rise to long-lived radioisotopes, Cr, Ba, Sb, Ag, Zn, Co ...

Peptide receptor radionuclide therapy (PRRT) is a promising way to treat patients with inoperable tumors or metastatic neuroendocrine tumors. This therapeutic strategy is using radiolabeled peptides, which are capable of selective biding to receptors overexpressed in the cancer cells. One of the group of receptor-avid peptide used in the PRRT are the analogues of somatostatin (SST) connected to...

The production of radioisotopes for use in biomedical procedures such as diagnostic imaging and/or therapeutic treatments is achieved through nuclear reactions in reactors or from charged particle bombardment in accelerators. In reactors the nuclear reactions are initiated with neutrons while in accelerators the typical charged particle reactions utilize protons although deuterons and α−particl...

Auger electrons and characteristic X-rays, collectively named as atomic radiation, are emitted following atomic ionization. Radioisotopes that emit Auger electrons have been of particular interest as therapeutic agents. This is primarily due to its short range in tissue, controlled linear paths and high linear energy transfer of these particles. Their biological effect is very localised thus ma...

O NLY A FEW YEARS after the discovery of artificial radioisotopes by the Joliot-Curies in 1934, de Hevesy, Chievitz and Ottesen used tracers in hematology. Even today, there are few areas in clinical medicine where as many radioisotopes are used both for investigative and diagnostic purposes as in hematology. Consequently, the methods of tracer studies are often described in the hematologic jou...
