Transportable measuring device for recording the UV-radiation dose as a protection against injury to the health of the skin

摘要

The invention relates to a device for recording and evaluating UVA, UVB and UVC radiation as a protection against injury to health by outputting an acoustic and optical warning signal upon expiry of a period of time fixed by various parameters. The design is selected such that the device can be worn without difficulty on the body or as a constituent of clothing. The computational program of the single chip computer employed preferably takes account of the skintype input, as a result of which the residence time (in the case of possibility of readjustment) is influenced, of the history of the radiation loading (for example of preceding days), the input of the sunscreen factor (corresponding lengthening of the residence time), the irradiation position (automatically in the case of devices of double-sided design, otherwise by appropriate input), the medically justifiable irradiation goal (at present 66% of the erythema threshold), as well as stored preset values which are derived, for example, from a dermatological consulation. In order to detect the radiation, use may be made of light-sensitive semiconductor components with suitable filter combinations or of the measurement of secondary emissions. Power is preferably supplied by means of a solar cell and buffer accumulator. IMAGE
