Non-destructive testing. Determination of the size of industrial radiographic sources. Radiographic method (British Standard)
This standard specifies the determination of the size of gamma radiographic sources of 0,5 mm or greater, made from the radionuclides Iridium 192, Ytterbium 169, Selenium 75 or Cobalt 60, by a method of radiography with X-rays. The source size of a gamma radiography source is an important factor which affects the image quality of gamma ray images. The source size is determined with an accuracy of +/- 10 % or 0,1 mm. This standard can be used for other radionuclides after validation.
