To achieve reduced backscatter during radiographic testing, masking the test piece is an effective method. This technique involves covering areas of the test piece that do not need to be exposed to radiation, which minimizes the amount of scatter radiation that can potentially reach the film or digital recording medium. By limiting the exposure area, less scatter will be produced, resulting in clearer radiographic images with improved contrast.

This method is particularly useful in reducing noise in the radiograph, as backscatter can create unwanted density in areas that are supposed to be clear, complicating the interpretation of defects or features of interest. Masking directly addresses the source of scatter by preventing radiation from interacting with certain parts of the component being tested.

Other methods such as increasing the source-to-film distance and using a lead filter can also contribute to reducing backscatter but may not be as straightforward in terms of directly addressing scatter from the test piece itself. Reducing exposure time primarily mitigates the effects of radiation on the film and does not specifically target backscatter. Thus, masking is a preferred method for effectively reducing backscatter during radiographic testing.
