This Part of SS 78 B series standards gives recommendations for the radiographic inspection of concrete. Up to approximately 500 mm thick, gamma ray sources are usually employed; above this thickness the use of high-energy X-rays is more appropriate. Recommendations are given on the factors which govern the quality of the radiographic image, namely the source characteristic, the arrangement of source, object and film in space, the film speed, the use of screens, the exposure time and the film development technique.
This standard is for the guidance of radiographers and the information of others involved.
NOTE 1. By law, radiography has to be carried out under the supervision of qualified personnel.
NOTE 2. Explanatory notes on the radiographic technique are given in Appendix A, and radiographic examples are given in Appendix B.
