What must be done when removing material from the beam enclosure?

When removing material from the beam enclosure, it is crucial to monitor it for radiation if it was present during beam operation. This is because the material may have been exposed to radiation during its time within the enclosure and could have accumulated radioactive contamination. Monitoring is a safety practice to ensure that personnel are not exposed to harmful levels of radiation and to prevent the spread of contamination.

This precaution aligns with the protocols in radiological safety, which emphasize the importance of assessing potential radiation hazards before handling any materials that have been associated with radiation-generating equipment. Understanding the radiation exposure history of the material allows for informed decisions regarding safe handling and disposal practices, minimizing risk to individuals and the surrounding environment.
