WebApr 24, 2024 · Ultraviolet (UV) radiation covers the wavelength range of 100–400 nm, which is a higher frequency and lower wavelength than visible light. UV radiation comes naturally from the sun, but it can also be created by artificial sources used in industry, commerce and recreation. The UV region covers the wavelength range 100-400 nm and is divided ... WebMar 21, 2024 · They are also known as non-stochastic effects to contrast them with chance-like stochastic effects (e.g. cancer induction ). These effects depend on dose, dose rate, dose fractionation, irradiated volume and type of radiation ( linear energy transfer (LET) ). Deterministic effects have a threshold below which the effect does not occur.
