Determines the size of gamma radiographic sources of 0,5 mm or more, made from radionuclides Iridium 192, Ytterbium 169, selenium 75 or Cobalt 60 by a radiography procedure with X-rays. Source size is an important factor which affects quality of gamma ray images. It is determined with accuracy of 0,1 mm max. Exposure of the human body to gamma or X-rays can be highly damaging to health, so when using X-ray equipment or radioactive sources, it is important that appropriate legal requirements are applied.
