UVA在一天中的大部分时间都存在,遵循着可见光的变化规律;而UVB则在上午10点与下午4点之间最高,尤其是在中午时分。UVA照射的另一特征是能够穿透玻璃,而UVB则基本上都会被吸收。所以,即使在室内都可以接收到高剂量的UVA,而诱导红斑剂量的UVB会被阻隔...

Phototherapy (UVA and UVB)Phototherapy or light therapy uses specific wavelengths of light in the ultraviolent (UV) range to treat certain skin disorders. Ultraviolent light has anti-inflammatory properties in the skin and can be used to decrease skin inflammation and decrease skin itching. It can...
While the mutagenic and carcinogenic properties of longwave UV light (UVA) are well established, mechanisms of UVA mutagenesis remain a matter of debate. To elucidate the mechanisms of mutation formation with UVA in human skin, we determined the spectra of UVA- and UVB-induced mutations in ...
