[Dermatitis solaris in newborn infants following phototherapy with a halogenide radiation unit].

Two cases of dermatitis solaris in newborns after phototherapy with a halide burner gave reason to measure the UV-B radiation emitted by the instrument used. Values between 0.8 microW/cm2 and 1.8 microW/cm2 were found. In small areas under the lamp housing the intensities of the UV-B radiation reached up to 10 microW/cm2. These high intensities are caused by the design of the lamp housing. Especially in connection with aluminium foil used to increase the efficacy of the therapy skin leasons as described may be produced.
