What percentage of the general public's exposure to human-made radiation is attributed to medical and dental radiation?

The correct answer indicates that a significant portion of human-made radiation exposure to the general public comes from medical and dental procedures, estimated at about 90%. This statistic is important in understanding the impact of these procedures on public health and the overall radiation exposure landscape.

Medical and dental applications, including X-rays, CT scans, and radiation therapy, play a critical role in diagnosis and treatment, leading to increased exposure from these sources. The high percentage underscores the importance of radiation safety protocols in healthcare settings to minimize unnecessary exposure.

Given the context of the choices, the percentages of exposure attributed to alternative sources, such as nuclear power or industrial applications, are considerably lower. Knowing that medical and dental radiation constitutes such a high fraction prompts discussions on the necessity of balancing the benefits of medical imaging and therapies against the potential risks associated with radiation exposure. Understanding this proportionality helps inform policies and practices aimed at optimizing patient safety in medical environments.
