Radiation Safety Practice Exam

What does ALARA stand for in radiation safety practices?

1. As Low As Reasonably Achievable

2. As Little As Reasonably Allowed

3. All Levels As Required Annually

4. Average Level of Radiation Attenuation

The correct answer is: As Low As Reasonably Achievable

In the context of radiation safety, ALARA stands for "As Low As Reasonably Achievable." This principle emphasizes the importance of minimizing radiation exposure to individuals, workers, and the public while also considering economic and societal factors. The concept of ALARA is based on the understanding that while some radiation exposure is inevitable, efforts should be taken to keep it as low as possible without incurring unreasonable costs or sacrificing safety measures. Implementing the ALARA principle involves using various strategies, such as reducing the time spent near radiation sources, increasing shielding between individuals and radiation sources, and maintaining adequate distances from these sources. By adhering to ALARA, professionals in the field of radiation safety can effectively balance operational needs with health and safety concerns, thereby reducing the likelihood of radiation-related health risks.
