What is commonly used to provide an indication of cumulative radiation dose over time?

A personal radiation monitor is the most reliable tool for providing an indication of cumulative radiation dose over time. These devices, such as dosimeters, are worn by individuals working in environments where they may be exposed to radiation. They record the amount of radiation the wearer is exposed to over a specific period, allowing for ongoing tracking of cumulative exposure. This monitoring is critical for ensuring the safety and health of individuals in industrial radiography settings, where understanding exposure levels is essential for regulatory compliance and personal safety.

While options like a date log or an exposure logbook may contribute to tracking work performed or documenting exposure events, they do not measure radiation directly or provide a cumulative dose reading. Similarly, a radiation dose chart may offer reference information about dose levels, but it does not actively measure or document individual exposure over time. Therefore, the personal radiation monitor stands out as the most accurate and effective means of monitoring cumulative radiation dose.
