UV-treatment in dermatology. Equipment and methods in Norwegian university hospitals

The use of phototherapy and the phototherapy-equipment were studied in five Norwegian university hospitals. The indications and the methods used were relatively similar, as well as the equipment used for dosimetry. The spectra and irradiance from the phototherapy lamps were measured and the variations in these parameters were evaluated. It is discussed whether there is a need for closer control and standardization of these parameters. The UVA-irradiance that could be experienced by the persons employed in the departments was found to be lower than the recommended limits. 12 refs., 7 figs., 6 tabs
