What is the purpose of alarms in a DCD?

The purpose of alarms in a DCD (Data Collection Device) is to alert personnel when radiation hazards increase. This is critical in environments where radiation exposure is a concern, as timely alerts can facilitate immediate action to ensure safety. The alarm system serves as a vital safety mechanism, providing warnings to workers and allowing for quick responses to protect both individuals and the environment from harm. In settings involving radiation, understanding when levels cross safety thresholds is essential for complying with health and safety regulations.

The other choices do not align with the primary function of alarms in this context. While signaling breaks or lunch times is important for workplace scheduling, it does not pertain to safety monitoring. Indications of equipment malfunction, although significant, are not the specific focus of alarms designed explicitly for radiation hazards.
