Radioactive Isotopes of Gadolinium

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...

The Use of Two Radioactive Isotopes

There are 2 radioactive isotopes of iron suitable for use as biological tracers. One of these, Fe59, has a half life of 47 days and emits gamma rays and low energy beta rays. The other, Fe55, has a half life of about 5 years and emits low energy x-rays only. This paper describes how these 2 isotopes are prepared for red blood cell tracer studies, how biological samples containing the radioactiv...

The Clinical Value of Radioactive Isotopes

I AM very much honoured by your invitation that I should deliver an oration in this valuable and distinguished series that has been established in memory and honour of the life of Robert Campbell, and I wish to speak of the clinical value of radioactive isotopes. In the year in which the Robert Campbell memorial orations were founded, Rutherford had already detected faint scintillations on the ...
