Radiation Safety Practice Exam

Which of the following is NOT a common practice to keep internal exposures ALARA?

1. Personal hygiene practices

2. Routine radiation surveys

3. Working without monitoring

4. Dosimetry programs

The correct answer is: Working without monitoring

Keeping internal exposures As Low As Reasonably Achievable (ALARA) is a fundamental principle in radiation safety. The correct answer identifies a practice that contradicts this principle. Working without monitoring fundamentally undermines the ALARA strategy because monitoring is a critical component of managing radiation exposure. Without monitoring, individuals cannot assess the level of exposure they are receiving, nor can they implement necessary measures to minimize it. Continuous monitoring allows individuals to detect and respond to potential radiation hazards in real time, which is essential for safety. In contrast, personal hygiene practices, routine radiation surveys, and dosimetry programs are all established methods used to minimize internal exposures. Personal hygiene practices, such as regular hand washing and using appropriate protective equipment, can significantly reduce the risk of internal contamination. Routine radiation surveys help identify areas and situations where exposure levels may be higher, enabling proactive measures to reduce risk. Dosimetry programs track individual radiation exposure over time, allowing for informed decision-making regarding workplace safety and health. These practices collectively contribute to the overarching goal of maintaining exposure to radiation at the lowest levels possible while ensuring safety and compliance with regulatory standards.
