What key information should be included in a radiation exposure record?

The key information that should be included in a radiation exposure record is essential for monitoring and ensuring the safety of individuals who may be exposed to radiation. This information is crucial in assessing both individual and cumulative exposure levels, which can help in preventing radiation-related health issues.

Including the type of exposure provides context about how the individual was exposed, whether it was through X-rays, radioactive materials, or another source. Recording the dose received is vital, as it quantifies the amount of radiation that the individual has absorbed, which directly correlates to potential health risks. Documenting the date of exposure is important for tracking exposure over time and for understanding trends in radiation exposure, while the duration of exposure indicates how long the individual was exposed to the source of radiation. Together, this information forms a comprehensive log that can be critically analyzed for safety protocols and health monitoring.

While the other options may contain relevant information, they do not encompass the complete set of data necessary for a comprehensive radiation exposure record as effectively as the correct choice does.
