Non-destructive Measurement Technique Research Articles

Safeguarding of Nuclear Fuels

With the rapid expansion of the nuclear industry, safeguarding of nuclear materials against diversion and of nuclear facilities against sabotage becomes increasingly important both domestically and internationally. The USA safeguards research and development program will be reviewed with special emphasis on nondestructive measurement techniques for material accountability.

Radioactivity in wool.

WITH the development of highly sensitive γ-ray detectors, it has become possible to carry out nondestructive measurements of the low levels of γ-ray activity emitted by various biological materials. Since γ-ray measurements may be made rapidly without any special preparation or modification of the material measured, the application of this technique to agricultural research problems has much to recommend it. The advantages of the nondestructive γ-ray measurement technique appear to justify exploratory research to determine if such measurements may be used to estimate other factors to which they may be related1.
