Ultraviolet Light Penetrate Cell Walls

With the lights out and uv light shining on it the highlighter fluoresces.

Ultraviolet light penetrate cell walls.

If you look with just visible light you don t see much. Healthy climate germicidal uv and uvc lights are designed to control and eliminate biological contaminants. It is defined as the depth at which the intensity of the radiation inside the material falls to 1 e about 37 of its original value at or more properly just beneath the surface. Easily installed inside your ductwork these products emit powerful rays of ultraviolet light that penetrate the cell walls of biological contaminants on surfaces damaging their physiological structure so they can no longer grow multiply.

Penetration depth is a measure of how deep light or any electromagnetic radiation can penetrate into a material. Ultraviolet germicidal irradiation uvgi is a disinfection method that uses short wavelength ultraviolet ultraviolet c or uv c light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their dna leaving them unable to perform vital cellular functions. According to the study far uvc light can t penetrate the tear layer of the eye or the outer dead cell layer of skin. Uvgi is used in a variety of applications such as food air and water purification.

This means it s unable to reach and damage living cells in the body.
