Arrangement for irradiating a liquid with ultraviolet radiation. The arrangement comprises a low-pressure mercury lamp, placed inside a hermetically sealed housing. In addition, inside the housing a converter or a transformer is placed, such that the arrangement may operate from a safe, lo w supply voltage. The housing moreover contains a humidity sensor, which switches off the supply voltage as soon as a crack or another leak is detect ed in the housing. The arrangement may advantageously be incorporated into a shower head or another sanitary provision, when a complete sterilisation of the supplied water is desirable.
