Radiation Safety Practice Exam

Why does radioactive material require special disposal?

1. Many isotopes will decay quickly.

2. They are hazardous to human health.

3. Many isotopes will remain radioactive for a long time.

4. They can be reused safely.

The correct answer is: Many isotopes will remain radioactive for a long time.

Radioactive materials necessitate special disposal procedures primarily because many isotopes will remain radioactive for an extended period. This long-lived radioactivity poses significant risks, as these isotopes continue to emit radiation, which can be harmful to both human health and the environment if not properly managed. Safe disposal methods are critical to ensure that these materials do not contaminate soil, water, or air, thereby safeguarding public health and ecological systems over time. The prolonged radioactivity of certain isotopes means that they can have a lasting impact, necessitating careful containment and storage solutions to prevent exposure or accidental release. Regulations and guidelines govern the disposal of radioactive waste to mitigate these risks, emphasizing the importance of effective management strategies for materials that may remain hazardous for hundreds or even thousands of years.
