ASNT Industrial Radiography Radiation Safety Practice Test

Which of the following is NOT a type of installation used in radiography?

1. Field

2. Open

3. Fixed

4. Temporary

The correct answer is: Temporary

In the context of radiography, installations refer to the setups where radiographic examinations are conducted. The terms "field," "open," and "fixed" describe specific configurations where radiographic equipment is utilized. Field installations typically refer to setups that are mobile and can be deployed in various locations, such as construction sites or remote areas. Open installations often relate to environments where the radiation source is not enclosed and can be more flexible in terms of use. Fixed installations indicate that the equipment is permanently installed in a specific location, providing stability and consistent operating conditions for radiographic work. Temporary installations, on the other hand, imply that the setup is not intended for long-term use and lacks the permanence or defined operational framework seen in the other types. While temporary setups can be used in radiographic operations, they do not constitute a distinct type of installation as recognized in the primary categories. Therefore, the answer correctly identifies "temporary" as not being a standard type of installation in radiography.
