Leak testing of radioactive sources

The British Journal of Radiology, 1969
In considering leak testing, the Factories Ionising Radiations (Sealed Sources) Regulations, 1969 (Regulation 34, para 4) refer to permanently installed radioactive sources. In this Regulation it is stated that testing is required at least every 26 months, of “(a) every immediate container or bonding which forms part of a sealed source; or (b) every ...

A Calculator for Linear Radioactive Sources

The British Journal of Radiology, 1946
The 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, 1954
Primary 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 ...
