Radiographer—An individual who performs radiographic operations or an individual in attendance at a site where radiation producing machines are being used who personally supervises industrial radiographic operations.
Radiographer’s assistant—An individual who, under the personal supervision of a radiographer, uses radiation producing machines or radiation survey instrumentation.
Radiographer trainee—An individual who is in the process of becoming a radiographer’s assistant or a radiographer.
