Uv penetration window glass
Miscellaneous
In brief, some types of UV light can pass through window glass. When produced by the sun, UV-C does not penetrate the earth's atmosphere.
UV radiation from the sun, associated with about 90 percent of all skin has proven that skin exposed to sun shining through window glass.
Description:Butler MD When thinking about sun exposure, you might envision yourself on the beach or exercising outdoors. Research increasingly points to ultraviolet A UVA radiation penetrating through car windows. UV radiation from the sun, associated with about 90 percent of all skin cancers, reaches the earth as long- wavelength UVA and shortwave UV B rays. UV exposure is cumulative, and research has proven that skin exposed to sun shining through window glass, even in the office, can over time lead to significant skin damage. In a US study by Singer, et al, the researchers found asymmetric photodamage sun- induced skin damage on the face, with more brown pigment color and deeper wrinkles on the left. This finding is especially pronounced in men, who more consistently spend time driving cars over a lifetime.
