紫外线辐射（Ultraviolet Radiation，简称UV）是电磁波谱中介于可见光与X射线之间的不可见光辐射，其波长范围为10纳米至400纳米。根据国际非电离辐射防护委员会（ICNIRP）的分类标准，紫外线可进一步分为UVA（315-400 nm）、UVB（280-315 nm）和UVC（100-280 nm）三个波段。太阳是主要自然来源，其中UVC被地球臭氧层完全吸收，而UVA和UVB可到达地表。
紫外线辐射具有双重生物效应：适度接触UVB可促进皮肤合成维生素D，对骨骼健康至关重要（美国国家生物技术信息中心，NCBI）；但过量暴露会导致DNA损伤，引发皮肤癌变（世界卫生组织数据）。美国皮肤病学会建议采取防护措施，如使用SPF30+防晒霜、穿戴宽檐帽和紫外线防护服。
工业领域利用紫外线特性开发出多种应用技术，包括水处理消毒（美国环境保护署认证UVC杀菌效率）、荧光检测和光固化工艺等。气象监测中紫外线指数预报系统由世界气象组织与WHO联合开发，用于指导公众合理安排户外活动。
ultraviolet radiation（紫外线辐射）是电磁波谱中介于可见光与X射线之间的辐射类型，具体解释如下：
基本定义与波长范围
ultraviolet radiation指波长在100-400纳米之间的电磁波。其波长比可见光短，但比X射线长，属于不可见光。
分类与特性
根据波长可细分为：
主要来源与作用
自然来源主要为太阳光，人工来源包括紫外线灯、焊接电弧等。其作用涵盖：
注意事项
过量接触可能导致皮肤癌、白内障等健康问题，需通过防晒霜、防护镜等减少暴露。英文中常简称为UV radiation，同义词包括ultraviolet light、UV等。
