What is the best way to monitor whole-body radiation dose?

The best way to monitor whole-body radiation dose is through the use of a personnel dosimeter. These devices are specifically designed to measure the amount of radiation exposure received by individuals working in environments where they might be exposed to ionizing radiation.

Personnel dosimeters accumulate exposure over time and can provide an accurate record of the dose received, often represented in units such as millisieverts (mSv). They are typically worn on the body, allowing for real-time tracking of radiation exposure, which is crucial for ensuring that individuals do not exceed recommended dose limits.

While other options like film badges and radiation survey meters have their uses, they don't provide the comprehensive monitoring that personnel dosimeters do. Film badges, for instance, require development to produce results, which may not be timely for ongoing monitoring. Radiation survey meters are primarily used to measure radiation levels in the environment rather than personal exposure. Environmental dosimeters monitor background radiation in a specific area, but they do not account for the individual's specific exposure. Thus, personnel dosimeters stand out as the most appropriate tool for monitoring whole-body radiation dose in occupational settings.
