This radiation is almost entirely blocked by the Earth’s atmosphere and the ozone layer, meaning natural UV-C from the sun never reaches human skin. 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.

This radiation can pass through standard window glass and clear plastics, making it an inescapable part of the indoor environment. Scientists divide this range into three primary zones based on wavelength, photon energy, and interaction with matter.
UV-B photons carry higher energy than UV-A, primarily affecting the outer layers of the skin—the epidermis. The Science of UV Classification Ultraviolet light occupies the portion of the electromagnetic spectrum between visible light and X-rays, characterized by wavelengths roughly between 10 and 400 nanometers.

This breakdown into specific bands allows for a more nuanced approach to protection, treatment, and technological implementation. 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.
