What does it mean if a detection device has a high detection limit?

When a detection device has a high detection limit, it indicates that it is less sensitive to radiation. This means that the device requires a relatively high level of radiation in order to produce a measurable signal or response. In practical terms, it may not be able to detect low levels of radiation effectively, which is critical in many radiological applications where early detection of low radiation levels is essential for safety and monitoring purposes.

In this context, a device characterized by a high detection limit may miss significant radiation exposure events that occur below that limit. Therefore, understanding the sensitivity of detection devices is crucial, as it determines their effectiveness in different scenarios involving radiation monitoring.
