UV radiation measurement
UV radiation measurement quantifies the intensity of ultraviolet rays from the sun reaching the Earth's surface. This is typically expressed using the UV Index, a scale from 0 (minimal risk) to 11+ (extreme risk), indicating the potential for skin and eye damage. Devices called UV sensors or meters detect the amount of UV energy in the environment, helping people understand when sun protection measures like sunscreen or clothing are needed. These measurements also aid in assessing environmental impacts and guiding public health recommendations for safe outdoor activities.
