Recent developements in Computerised Axial Tomography, non-destructive testing of materials, and elemental analysis have encouraged a renewed theoretical and experimental interest in the determination of attenuation coefficients. In particular, the low energy region, < 100 keV, …

The development of magnox fuel cans at the Heston Laboratories of A.P.C. Ltd. required a non-contact method of measuring fuel can temperature during heat transfer tests. Infra-red techniques were examined and a two colour ratio pyrometer was selected as offering the greatest pro…
