A radiograph is considered rejectable when which of the following occurs?

A radiograph is deemed rejectable when there are blemishes in the area of interest on the film because blemishes can obscure or distort critical information needed for assessing the integrity of the weld. These imperfections may arise from various factors, including dust, scratches, or processing issues, affecting the quality and clarity of the radiographic image. Since radiographs are used to identify potential defects or irregularities in welds, any blemishes in the area being inspected can lead to misinterpretation or overlooking significant flaws, which could compromise safety and reliability in the welding components being evaluated.

In contrast, developing the radiograph outside standard temperature may produce an image of poor quality but does not necessarily mean that it is altogether rejectable if the essential details remain intact. Similarly, equal density on both sides of the film could indicate incorrect exposure or processing, but this does not directly signify a rejectable condition unless specific criteria for examination are not met. The presence of a dark image of a "B" on a clear background could suggest an issue with the image quality, yet it does not directly reflect the clarity needed to assess weld integrity. Therefore, while these other factors could affect the quality of radiographs, it is the presence of blemishes specifically in the area of interest
