Scientists divide this range into three primary zones based on wavelength, photon energy, and interaction with matter. Biological Impact and Regulation Exposure to UV-B is essential for the endogenous production of vitamin D, a critical nutrient for bone health and immune function.
Understanding Shortwave, Mediumwave, and Longwave UV Radiation
While often grouped together as UV radiation, the energy output and biological effects vary significantly across the spectrum. UV-C: The Germicidal Range Absorption and Artificial Generation Short-wave ultraviolet C (UV-C) encompasses wavelengths from 100 to 280 nanometers and possesses the highest energy of the three types.
UV-A: The Aging Rays Characteristics and Penetration Long-wave ultraviolet A (UV-A) spans wavelengths from 315 to 400 nanometers, making it the least energetic but most prevalent form of ultraviolet radiation reaching the Earth’s surface. UV-B photons carry higher energy than UV-A, primarily affecting the outer layers of the skin—the epidermis.

UV-B: The Burning Rays Characteristics and Interaction Medium-wave ultraviolet B (UV-B) covers wavelengths from 280 to 315 nanometers and is largely absorbed by the ozone layer, though a significant portion still reaches the ground. It is widely utilized in hospitals to sanitize surfaces, in water treatment plants to eliminate pathogens, and in HVAC systems to improve air quality.
