A Calculator for Linear Radioactive Sources
The British Journal of Radiology, 1946The device to be described performs graphically some of the operations involved in calculating the γ-ray dose-rate at a point near a screened linear radioactive source. It has proved useful in a hospital physics department where evaluation of the dose rates at a number of points near a group of such sources is often required, the accuracy obtainable ...

Standardization of Radioactive Sources
Annual Review of Nuclear Science, 1954Primary standards of radioactivity are in some ways, analogous to fixed points in the temperature scale in that each can be used for comparison with "unknowns" not too far removed from the standard. Over a thousand radio active species are known to exist, but only a comparatively few satisfy such basic requirements for primary standards as: known ...

A New Type of Radioactive Wire Source
Radiology, 1967For interstitial radiotherapy there is a marked tendency toward the replacement of radioactive needles by radioactive wires (most commonly 182Ta and 192Ir). The wires have the advantages of flexibility, malleability, and safe fixing in the tissues. In addition, there is a possibility for afterloading (3, 5, 6, 8, 12, 13).

1976
In chapter 2, radioactivity was defined as the spontaneous change of one nuclide into another with the emission of radiation. The nuclides are said to be radioactive and the transformation process is referred to as radioactive decay. Radioactive decay can be accompanied by the emission of different types of radiation, the most common being alpha, beta ...
