Vitamin D is known as the sunshine vitamin. During exposure to sunlight the skin transforms
7-dehydrocholesterol into vitamin D 3. Throughout evolution vitamin D 3 has played a …

Skin cancers are the most common malignant tumors of white-skinned people. It is well
established that nonmelanoma skin cancer is almost entirely caused by chronic exposure to …

The health risks associated with ozone depletion will principally be those due to increased
ultraviolet B (UV-B) radiation in the environment, ie, increased damage to the eyes, the …

The body gains vitamin D through both oral intake (diet/supplementation) and synthesis in
skin upon exposure to ultraviolet radiation (UVR). Sun exposure is the major source for most …

The potential health effects of elevated levels of ambient UV-B radiation are diverse, and it is
difficult to quantify the risks, especially as they are likely to be considerably modified by …

Skin cancer is the most common cancer diagnosed in the United States, and its incidence
continues to rise. Epidemiological studies have documented that excessive sun exposure …

The adverse effects of solar ultraviolet radiation on the skin are well documented, especially
in fair-skinned people. These can be ameliorated by photoprotection strategies advocated …

There is highly significant evidence that non‐melanoma skin cancers are primarily due to
chronic repeated exposure to solar ultraviolet radiation, and that there is a significant …

Ultraviolet climatology is outlined including atmospheric ozone and factors affecting
terrestrial ultraviolet radiation. Solar dosimetry in photobiology and terrestrial UV monitoring …

Vitamin D is the sunshine vitamin for good reason. During exposure to sunlight, the
ultraviolet B photons enter the skin and photolyze 7-dehydrocholesterol to previtamin D 3 …
