Question:
Can UV rays penetrate water? For example: Standing waist deep in a pool of water, will my legs be protected as my upper body burns?


Replies:
Water does scatter U.V. radiation, and the surface of the water will reflect a part of incident U.V. radiation so your legs are more protected.

Terry,

Sunlight's UV component will not penetrate water very far. Indeed, if overexposed, the parts of you that are above water will burn -- even faster than if you were on dry land because the surface of the water reflects the radiation. As a result, you get hit with the direct and well as the reflected rays.

Regards,

U.V. radiation (depending upon the wavelength) penetrates water to some extent, but not far, because various components in the water absorb the U.V. radiation, and in addition water scatters the U.V. radiation. So, YES, your exposed upper body will burn more quickly than your legs submerged in water.
