Radiography Testing - NDT Inspection. Radiographic Testing (RT) is a non-destructive testing (NDT) method which uses either x-rays or gamma rays to examine the internal structure of manufactured components identifying any flaws or defects. In Radiography Testing the test-part is placed between the radiation source and film (or detector).

Taking into account the fact that in the quarries the radiation originates from the floor and the walls, the exposure may increase by 10 to 30 % depending on the local situation. The gamma ra- diation levels at the quarries visited are thus calculated to be 0.15 µSv/h to 0.55 µSv/h. The quarry that uses the Blekinge Coast Gneiss

Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world's use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.

Areas that practice quarrying often experience challenges with the infrastructure since the quarry activities can destroy road patterns, causing more congestion and traffic on the roads, especially within small communities. The Bottom Line. Quarrying can harm the environment, although many of the negative effects can be controlled or managed.
