Radiation Safety Practice Exam

Which determination is made by the RSO regarding dosimetry?

1. If an individual can perform work regardless of radiation exposure

2. Whether an employee needs training on dosimetry

3. If dosimetry may be needed based on exposure risk

4. Which dosimeter is best for the job

The correct answer is: If dosimetry may be needed based on exposure risk

The determination made by the Radiation Safety Officer (RSO) regarding dosimetry is centered on assessing the potential exposure risk to employees. The RSO evaluates the work environment and the nature of the tasks being performed to decide if dosimetry is required as a protective measure. This assessment is crucial because it ensures that individuals working with or around radiation are monitored appropriately to safeguard their health and manage their occupational exposure. Deciding whether dosimetry may be needed based on exposure risk is a proactive approach that helps to identify situations where employees could be exposed to radiation levels that warrant monitoring. By doing so, the RSO can implement the necessary safety measures and compliance with regulations, ensuring that workers' radiation doses are kept within safe limits. This determination is not merely about individual capabilities (like whether an individual can perform work regardless of radiation exposure) or the need for training on dosimetry. While those aspects are important in a broader safety program, they are secondary to the RSO's evaluation of the specific need for monitoring based on risk. Additionally, while choosing the best dosimeter is imperative, it arises after the need for dosimetry has already been established; thus, it is not the primary determination made by the RSO in this context.
