Radiation Safety Practice Exam

Which of the following is not a basic component of most modern RADIAC instruments?

1. Meter

2. Detector

3. Battery

4. Transmitter

The correct answer is: Transmitter

The correct choice is not a basic component of most modern RADIAC instruments. RADIAC, which stands for Radiation Detection, Indication, and Computation, typically consists of several essential components to effectively measure and indicate radiation levels. Modern RADIAC instruments primarily include a meter, which displays the measurements of radiation. This is crucial for users to understand the level of radiation present in their environment. The detector is another vital component; it is responsible for sensing the radiation. Various types of detectors can be used depending on the specific application and the type of radiation being measured. Additionally, these instruments require a power source, which is usually a battery. The battery is critical for operating the instrument and ensuring that it can function continuously during measurements. While some specialized RADIAC systems may incorporate a transmitter for data communication or remote monitoring, it is not considered a fundamental component common to all modern RADIAC devices. Thus, the lack of a transmitter in the core functionality of standard RADIAC instruments makes this the correct choice.
