    Abstract: A hand-carried device (10) for measuring UV-radiation is provided with a radiation filter (13), a sensor (12) and with a signal processing portion between the sensor and a digital read-out unit (31). To ensure that, with such a hand-carried device for measuring radiation, only a single part of the measurement device has to be handled, and that as is customary the read-out unit can be read easily in any measurement position, it is envisaged that the sensor (12) is located together with the signal processing part and the digital read-out unit (31) in a joint housing (26) and that a position-dependent switch is provided together with a switchable coding circuit, by which the digital read-out unit (31) can be controlled in such a manner that it is legible in a position which is rotated through 180o in relation to its plane.

    Abstract: The lamp comprises a low pressure mercury vapour lamp, with a luminophore layer of strontium aluminate activated with Ce (SACe) followed by a glass filter with a lower absorption edge of 295 nm. Pref. the filter is made of conventional soda-lime glass as used for ordinary light bulbs or tubes, and the glass pref. contains traces of iron. The filter is pref. formed by the glass tube of the lamp, the tube being coated on its bore with the luminophore. This inexpensive high intensity lamp provides UV of 300-330 nm for treating psoriasis, without providing UV below 295 nm which could be harmful. The lamp can also be used for treating acne, forming vitamin D or hardening polymers.
