Radioactive Isotopes in Medicine

Radioactive isotopes in medicine: a review.

The following account is very selective: no attempt is made to deal exhaustively with radioisotope applications. In particular, practically no mention is made of treatment using, e.g., 1311, 198Au, or 90Yt, or of the literature dealing with the localizing of tumours, much of which is unprofitable. Circulatory dynamics, e.g., cardiac output, are ignored, as are most biochemical investigations wh...

Current Practice GROWING POINTS Radioactive Isotopes in Clinical Medicine

There are four fundamental atomic particles-the proton, the neutron, the electron, and the positron. The proton has mass and a unit positive electrical charge. The neutron has mass and no charge. The electron has very small mass compared with the proton and neutron, and has unit negative electrical charge. The positron is the positively charged counterpart of the electron, having equal mass and...

The Radioactive Isotopes

Mass separator for radioactive isotopes

A new isotope separator has been designed, constructed, and put into routine operation for separation of 133Xe providing a major advancement and significant cost reduction in preparation of this radioactive isotope. The design features and advantages are discussed that expedite high purity separation of relatively small quantities of this isotope. These advantages could be easily used to expedi...
