适用范围：This standard specifies the determination of the size of gamma radiographic sources of 0,5 mm or greater, madefrom the radionuclides ridium 192, Ytterbium 169, Selenium 75 or Cobalt 60, by a method of radiography withX-rays. The source size of a gamma radiography source is an important factor which affects the image quality ofgamma ray images.The source size is determined with an accuracy of + 10 % or 0,1 mm max.This standard can be used for other radionuclides after validation.
