摘要

依靠光辐射的生物医学应用,尤其是激光的出现,在过去 20 年里经历了指数式的增长。现在,强大的光源不仅出现在大学、医院和工业中,还出现在美容中心,用于去除纹身等工作,甚至出现在我们的家中。尽管激光被广泛使用,但对激光相关风险的管理,尤其是在非研究环境中的管理,并没有跟上激光普及的步伐。虽然人们对眼睛和皮肤直接暴露于辐射所带来的风险已经有了相对深入的了解,但对反射和漫射辐射所带来的危害的了解和监控仍然较少。因此,亟需对使用激光和非相干光源的空间中潜在的眼睛和皮肤危害进行评估。这就需要对反射表面进行详细分析,尤其要重点评估其在相关波长范围内的反射特性。本研究调查了生物医学环境中常用材料(包括织物、塑料和金属)在从 250 纳米(UVA)到可见光的宽光谱范围内以及高达 25 微米的红外(IR)区域内的反射率和透射率(如相关)特性。使用分光光度技术测量了镜面反射光谱(45° 入射角)和漫反射光谱,并提供了一个直接的参数来对不同表面的镜面/漫反射行为进行分类。此外,还利用傅立叶变换红外光谱仪对红外范围内的小角度反射率进行了测量。在使用光辐射的环境中,了解所用材料的光学特性有助于准确评估相关风险。这有助于确定适当的预防措施和制定更安全的规程,既有利于操作人员,也有利于患者和公众(如适用)。为此,已着手建立一个材料反射特性数据库。

Risks associated with laser radiation reflections in a healthcare environment: a surface reflectance study in the range 250 nm – 25 μm
Biomedical applications relying on optical radiation, particularly with the advent of lasers, have experienced exponential growth in the last 20 years. Powerful optical sources are now found not only in universities, hospitals, and industries but also in beauty centers, used for tasks such as tattoo removal, and even in our homes. Despite their widespread use, managing the risks associated with lasers, particularly in non-research contexts, has not kept pace with their proliferation. While the risks associated with direct exposure to radiation to the eye and skin are relatively well understood, the hazards posed by reflected and diffuse radiation remain less characterized and monitored. Therefore, there is a critical need to assess potential eye and skin hazards in spaces where lasers and non-coherent light sources are used. This necessitates a detailed analysis of reflective surfaces, with particular emphasis on evaluating their reflectance characteristics at relevant wavelength ranges. This study investigates the reflectance and transmittance (where relevant) properties of commonly used materials in biomedical settings, including fabrics, plastics, and metals, across a broad spectrum from 250 nm (UVA) to visible light and into the infrared (IR) region up to 25 μm. Both specular (at 45° incidence) and diffuse reflectance spectra were measured using spectrophotometric techniques and used to provide a straightforward parameter to classify the specular/diffusive behavior of the different surfaces. Besides, small-angle reflectance measurements in the IR range were performed by Fourier transform infrared spectrometry. The knowledge of the material optical properties used in environments where optical radiation is employed allows for accurate assessment of associated risks. This facilitates the determination of appropriate preventive measures and the establishment of safer protocols, for both operators and, where applicable, patients and the general public. For this scope, the creation of a database of material reflective properties has been initiated.
