Radiation Safety Practice Exam

For a detector that is not permanently mounted, what is it referred to?

1. Probe

2. Sensor

3. Module

4. Attachment

The correct answer is: Probe

When discussing radiation detection devices, a detector that is designed to be movable or not permanently fixed is typically referred to as a "probe." Probes are essential tools in radiation safety because they can be used in various locations and applications, allowing for flexible monitoring of radiation levels. They can be handheld or connected to other equipment, providing real-time data on radiation exposure in different environments. Probes often come with specific designs and features that enable them to detect different types of radiation (such as alpha, beta, or gamma radiation) and are used in many scenarios, from field investigations to laboratory measurements. This versatility is fundamental to their function, allowing users to conduct radiation surveys wherever required. While sensors also play a role in detecting radiation, the term is broader and can refer to any device that measures a physical quantity, not exclusively designs intended for portable use. Modules typically refer to self-contained systems that might include probes but can encompass broader technological setups, often permanently installed for continuous monitoring. Attachments often imply add-ons or components that pair with other systems rather than stand-alone detection devices. Therefore, the specific term "probe" is the most accurate in this context.
