Abstract

The invention relates to a mercury amalgam low pressure radiator having a cylindrical piston comprising two ends, and being permeable for UV radiation, wherein one end of the piston holds the electrodes and the other end of the piston is equipped with the amalgam deposit. In this manner a particularly robust radiator having compact dimensions is obtained, especially where installation is in a hung position.
