Wolf 359, a red dwarf star just 7.8 light-years away, could host planets, but extreme X-ray and ultraviolet radiation make ...

Unfortunately, UV-A exposure is suspected as a cause of cataracts (clouding of the lens). UV radiation is a known carcinogen for human skin. In addition to cancer induction, erythema (sunburn), and ...

Solar ultraviolet radiation is one of the causes of a series of eye diseases, including cataracts and a type of corneal ...

Skin cancer incidence is rising, largely due to prolonged UV exposure. Vitamin D, produced by sun exposure, may help prevent ...

Ultraviolet light in sunlight can cause the ... They are a form of nuclear radiation. High energy waves such as X-rays and gamma rays are transmitted through body tissues with very little absorption.

But it didn’t work at higher frequencies. According to their math, as the frequency of emitted radiation tended toward the ultraviolet range, the output energy would have to be infinite ...

It’s notoriously difficult to predict when the sun will belch out a large solar flare — an explosive burst of radiation that directly affects Earth’s atmosphere.

Skiers and snowboarders in high-altitude regions face increased risk of sunburn due to high albedo from fresh snow reflecting ...

Here's a tour that begins with radio waves and takes you through microwaves, infrared radiation, light, ultraviolet radiation, and X-rays. The tour ends with gamma rays, the potentially deadly ...
