What personal monitoring device(s) must a radiographer wear when working with radioactive material?

The correct choice indicates that a radiographer must wear multiple personal monitoring devices when working with radioactive material for effective safety monitoring. The inclusion of a pocket dosimeter, a film badge or TLD (thermoluminescent dosimeter), and an alarm ratemeter ensures comprehensive monitoring of radiation exposure.

A pocket dosimeter provides real-time dose readings, enabling immediate awareness of exposure levels. The film badge or TLD records cumulative exposure over time, which is essential for maintaining records and assessing long-term radiation safety. The alarm ratemeter serves as an additional safety measure, giving audible or visual alerts when radiation levels exceed preset thresholds, thus enhancing the protective measures for the radiographer.

This combination of devices allows for a multi-faceted approach to radiation safety, ensuring that different aspects of radiation exposure are monitored and that the radiographer remains within safe exposure limits.
