Cancer radiotherapeutic treatment

Such systems are called radioisotope generators. Rn is sometimes used for the radiotherapeutic treatment of cancer. This product is isolated by separating it as a gas from the parent substance Ra which is normally in the form of solid or a solution of RaBr2. Rn grows into the radium sample with a half-life of 3.8 d. After a 2-week period, following a separation of radon from radiiun, approximately 90% of the maximum amount of radon has grown back in the radium sample. Consequently, it is useful to separate Rn each 2 weeks from the radium samples since further time provides very little additional radioactivity. The Rn is an a emitter the ther utic value comes from the irradiation of the tissue by the y-rays of the decay daughters Pb and Bi which reach radioactive uilibrium extremely rapidly with the Rn. 

The current study was undertaken to develop laboratory techniques and protocols for the preparation and evaluation of therapeutic radiopharmaceuticals and the selection of targeted radiotherapeutic compounds with potential use in cancer treatment. For the study, DOTA-[Tyr ]-octreotate (DOTATATE), a somatostatin cyclic peptide hormone analogue (TATE coupled) with a macrocyclic chelator (DOTA), was used because it has been...

In developed countries priority has been given to researches ainied at the development of magnetically guided medicinal preparations for complex chemo-, immuno-, radiotherapeutic, hyperthermia, and diagnostic actions. The trends associated with early diagnostics and cancer treatment at the cellular level are particularly relevant The mentioned circumstances have led to the choice of scientific issues described in this review.
