What are the two types of monitoring for radiation detection?

The correct choice identifies the two types of monitoring for radiation detection as periodic and continuous.

Periodic monitoring involves taking measurements at specific intervals, allowing operators to assess changes in radiation levels over time. This method is often used in environments where constant surveillance is not required but where it is still important to keep track of potential radiation exposure or contamination. The timing of these checks can be adjusted based on operational needs or known risk factors.

Continuous monitoring, on the other hand, allows for real-time detection and assessment of radiation levels. This approach is essential in situations where immediate response to changes in radiation is critical, such as in nuclear facilities or during a radiological emergency. Continuous monitoring systems typically utilize sensors that provide ongoing data to ensure any fluctuations are detected as they occur, enabling swift action if radiation levels become hazardous.

Both types of monitoring serve important roles in ensuring safety and compliance but are utilized differently based on the context and operational requirements.

Other options presented do not accurately reflect the recognized classifications of monitoring types in radiation detection.
