How does altitude affect UV radiation exposure?

At higher altitudes, UV radiation exposure increases due to a combination of factors. The atmosphere is thinner at elevated altitudes, which means there are fewer air molecules and particles to absorb and scatter UV radiation. Consequently, a greater percentage of UV rays reach the ground in these areas compared to sea level.

This increase in UV exposure is particularly important for individuals who engage in outdoor activities at high elevations, as they may be more susceptible to the harmful effects of UV radiation, including sunburn and increased risk of skin cancer. Therefore, understanding this relationship is crucial for effective sun protection and tanning practices, especially for those who frequent high-altitude locations.
