True or false: A personal dosimeter protects the wearer from ionizing radiation harm.

The statement is false because a personal dosimeter does not provide physical protection to the wearer from ionizing radiation; rather, it serves a different purpose. A dosimeter is a device worn by individuals working in environments where they may be exposed to radiation. Its primary function is to measure and record the amount of radiation exposure the wearer has received over time, thereby providing a means to monitor and assess radiation exposure levels.

Understanding the role of a dosimeter is crucial in radiation safety, as it helps individuals and safety professionals evaluate whether radiation exposure is within safe limits and can inform decisions about necessary protective measures. This is particularly important in occupational settings where radiation exposure may be a risk, allowing workers to take appropriate precautions based on their recorded exposure levels.

In contrast to the role of a dosimeter, various protective measures, such as lead aprons, shields, or distance from the radiation source, are employed to physically protect individuals from ionizing radiation.
