遠-紫外線LIGHT THAT KILLS MICROBES

UVC能夠殺死微生物、阻止疾病傳播的光Researchers are developing lamps that could stop the spread of disease

研究人員因為近來的大規模流行病，一直在尋找更多殺死病毒的方法；而，他們獲得的其中一項成果與「光」有關係。

眾所周知，紫外線UV光可以破壞諸如細菌及病毒等微生物；且已獲得使用作為醫院清潔劑及淨化空氣和水等用途——不過僅限於沒有人在場的時候。

這是因為紫外線分為三種：UVA、UVB、UVC，全都對人體有危害。

暴露在 UVA和UVB底下會導致皮膚癌，而UVB還是造成晒傷的原因。

絕大部分的UVC都會被地球大氣層吸收，不過UVC較為危險；人造UVC可以穿透皮膚和眼睛細胞的外層，直接破壞底下的活細胞。

然而，有一種稱為遠紫外線UVC的光，並不會穿透細胞外層。

不過，目前尚未出現這種遠紫外線對於人體的長期影響以及用在超過二十人之群體所組成的相關研究。

Owing to the recent pandemic, researchers have been on a quest to find more ways to kill viruses, and one result of their work involves light.

 It has long been known that ultraviolet (UV) light can destroy microbes such as bacteria and viruses. It is already used as a cleaning agent in hospitals and to purify air and water - but only when people aren't around. That's because there are three types of UV light: UVA, UVB and UVC, and they are all detrimental to humans.

UVA and UVB exposure can lead to skin cancer, while UVB is responsible for sunburns. UVC light is mostly absorbed by the Earth's atmosphere, but it is even more dangerous. Artificial UVC light can pass through the outer layer of skin and

eye cells to damage the living cells underneath.

 However, there is a type of UVC light, known as far-UVC, which does not pass through the outer layer of cells. But studies of the long-term effects of far-UVC on humans, as well as studies on groups comprising more than 20 people, are not yet available.
