UV radiation is generally highest in countries near the equator.
This is because the atmosphere absorbs less radiation closer to the equator, especially the ozone layer which acts as Earth's natural sunblock. The angle of the sun is also more direct, leading to higher intensity UV rays. Therefore, countries located closer to the equator tend to experience the highest levels of ultraviolet (UV) radiation. Specifically, regions with less atmospheric absorption and direct sunlight exposure see the most intense UV levels.
Several countries are known for experiencing very high UV levels:
- Australia: Due to its proximity to the ozone hole and clear skies.
- New Zealand: Similar reasons to Australia.
- Peru: High altitude and equatorial location contribute to high UV.
- Bolivia: High altitude and equatorial location contribute to high UV.
- Chile: Especially in the northern regions.
- Argentina: Particularly in the northern regions.
In summary, the highest UV radiation is typically found in countries near the equator, especially those with clear skies and less atmospheric protection like ozone. High altitude also contributes to higher UV levels.
