Measurements have been made of the spectral emission and irradiance from whole body ultraviolet irradiation units used in the treatment of psoriasis by photochemotherapy (PUVA). A total of ten units were studied, located at nine different treatment centres in England. The results showed that within the limits of experimental accuracy there was no significant difference in the profile of all spectra measured, although the measured value of irradiance compared with each centre's own UV-A meter showed wide discrepancies. There is poor documentation provided by manufacturers of UV-A meters on the meaning of the scale reading in mWcm-2, and it would seem expedient that some agreed calibration procedure for these instruments is forthcoming.
已对用于光化学疗法（PUVA）治疗银屑病的全身紫外线照射装置的光谱发射和辐照度进行了测量。共研究了10台装置，位于英格兰的9个不同治疗中心。结果表明，在实验精度范围内，所有测量光谱的轮廓没有显著差异，尽管与每个中心自己的UV-A计相比，辐照度的测量值存在很大差异。UV-A计制造商提供的关于以mW/cm²为单位的刻度读数含义的文件很少，看来迫切需要为这些仪器制定一些商定的校准程序。
