Gammagraphy
Evaluation of the filling level of post-tensioning grout in ducts
Gammagraphy is a non-destructive imaging method that uses gamma rays emitted by a radioactive source, such as cobalt or iridium. Interpreting the X-ray films obtained reveals the presence of injection voids and broken prestressing reinforcement. Conducting a gammagraphic survey prior to diagnosis enables targeted investigations.
As this technique is highly regulated due to the use of radioactive sources, Sixense collaborates with authorised partners to manage and interpret the investigations.
