What is the average daily exposure to natural background radiation measured in?

• A. 5-8 uSv/day
• B. 10-15 uSv/day
• C. 1-3 uSv/day
• D. 2-4 uSv/day

Answer: (A)

The average daily exposure to natural background radiation is typically measured in microsieverts per day (uSv/day), and the range of 5-8 uSv/day is generally accepted as the average exposure most individuals receive from natural sources such as cosmic rays, radon gas, and terrestrial radiation. This range encompasses various factors, such as geographic location, altitude, and individual lifestyle, which can all influence radiation levels. For example, people living at higher elevations tend to receive higher doses of cosmic radiation. This measurement reflects an average that accounts for the cumulative effect of these natural sources over time, providing a baseline for understanding health risks associated with radiation exposure.
