Recently, the nondestructive testing industry has made great strides to change their radiography process from film to digital radiography. These changes and advancements have allowed many companies to reduce the overall cost of their RT process and increase production. These are great for any NDT process and company, however, a radiographer needs to recognize and understand the key differences between film and digital radiography.
Many of the industrial standards that govern the qualification and certification of NDT personnel require additional formal training and experience hours (OJT) to transition from film (RT) to non-film or digital radiography. This requirement applies to current or previously certified film Level I, II, or III radiographers.
