Decomposition rate of ozone in water with ultraviolet radiation.

Stratospheric ozone depletion, ultraviolet radiation and health

To our forebears the sky was the realm of the gods, inaccessible to mere humans. Only 100 years ago, the few scientists studying environmental problems would have been incredulous at suggestions that, by the late twentieth century, humankind would have begun to change the composition and function of the stratosphere. Yet this has happened. After 8000 generations of Homo sapiens, this generation...

Measurement of solar ultraviolet radiation in Yazd, Iran

Background: Ultraviolet (UV) radiation is divided into three regions: UVA, UVB, and UVC. Both the quality and quantity of solar UV radiation vary with various factors including the elevation of the sun above the horizon, as well as absorption and scattering of UV photons by molecules in the atmosphere, notably ozone and clouds. It is clear that whereas a moderate amount of UV exposure ...
