ASNT Industrial Radiography Radiation Safety Practice Test

What is the most common type of installation employed in field radiography?

1. Closed

2. Mobile

3. Open

4. Fixed

The correct answer is: Open

In field radiography, the most commonly employed type of installation is mobile radiography. Mobile radiography setups are designed for portability, allowing them to be easily transported to various locations where radiographic work is needed, such as construction sites, manufacturing plants, or pipelines. This mobility is crucial for effectively conducting inspections, especially in dynamic environments where equipment needs to be moved frequently. Mobile radiography equipment is typically less cumbersome than fixed installations, promoting flexibility and access to hard-to-reach areas. It allows radiographers to set up on-site quickly and efficiently, catering to the immediate needs of the inspection and ensuring adherence to safety protocols without the constraint of a permanent location. While closed and open installations have their notable uses in specific circumstances, mobile setups dominate in field applications due to their versatility and convenience. Fixed installations, on the other hand, are generally reserved for environments where radiographic operations are conducted regularly and do not require the movement of equipment.
