紫外线在电磁波谱中属于非电离辐射 ,波长 1 0 0～ 40 0ｎｍ ,通常把波长 32 0～ 40 0ｎｍ的紫外线称为长波紫外线(ＵＶＡ)。ＵＶＡ的能量很弱 ,ＤＮＡ对ＵＶＡ的吸收作用极低 ,因此ＵＶＡ对ＤＮＡ的损伤往往被忽视。我们用单细胞凝胶电泳检测ＵＶＡ对原代培养人皮肤成纤维细胞
Ultraviolet light belongs to non-ionizing radiation in the electromagnetic spectrum, and has a wavelength of 100-200 nm. The ultraviolet light with a wavelength of 320-4000 nm is usually called ultraviolet ultraviolet (UVA). UVA energy is very weak, DNA absorption of UVA is extremely low, so DNA damage to UVA is often overlooked. We detected UVA on primary cultured human skin fibroblasts using single cell gel electrophoresis
