The proposal is for a radiation measuring device for protection from high u/v radiation with a special sensor (1) to detect the radiation, containing a photodetector with a semiconductor with a bandwidth of over 2.25 eV, and comprising a lens or lens system (2) with a positive focal length. The detector is arranged in the beam path in front of the focal point which occurs when radiation impinges in the peripheral region of the lens or lens system at an angle of incidence of zero degrees, and the arrangement and/or sensitivity ranges of the detector are such that, when radiation impinges at an angle of incidence of zero degrees, only a part of the radiation arriving through the lens or lens system is detected, an input device (8) for the input of parameters from outside, a signal processing unit (9) having a first device which assesses the received radiation intensity taking account of the input parameters and having a second device which generates a first signal corresponding to the assessment, and an output device (10) for the optical and/or audible indication of the result of the assessment. |
