DEVICE FOR DETERMINING THE APPROPRIATE EXPOSURE DURATION OF A PERSON TO ULTRAVIOLET RADIATION AND VARIANTS

摘要

The present invention relates to the field of medicine, more precisely to that of medical techniques, and can be used for determining the adequate exposure duration of a person to ultraviolet radiation. The device of the present invention comprises photo-receptors for measuring the biologically efficient intensity of the UV radiation as well as the reflection coefficient of the light by the skin. The device also includes a system comprising the appropriate exposure durations of a person to the UV radiation. The photo-receptors may consist of cameras provided with a light filter and with a photo-sensitive screen comprising strips which are graduated into corresponding measurable values. The photo-receptors may also consist of photo-converters for converting the UV radiation into an electric signal.
