Radiation Safety Practice Exam

What do hygiene practices focus on to keep internal exposures ALARA?

1. Reducing skin exposure

2. Minimizing intake of contaminants

3. Increasing protective barriers

4. Extending exposure time

The correct answer is: Minimizing intake of contaminants

Hygiene practices in radiation safety primarily focus on minimizing the intake of contaminants to keep internal exposures As Low As Reasonably Achievable (ALARA). Internal exposure to radiation often occurs through the ingestion or inhalation of radioactive materials. By implementing effective hygiene practices, such as ensuring clean hands, maintaining clean work environments, and using appropriate personal protective equipment, individuals can significantly reduce the likelihood of contaminating themselves and, consequently, their internal exposure to radiation. Minimizing intake of contaminants is crucial because internal exposure can pose serious health risks, including increased likelihood of cancer or other radiation-induced illnesses. By controlling the amount of radioactive substances that enter the body, individuals can maintain their exposure levels at a minimum while fulfilling their responsibilities in environments where radiation is present. Thus, the correct answer reflects the essential focus of hygiene practices in radiation safety protocols.
