Abstract

The invention relates to an apparatus for measuring the radioactive concentration of a liquid, comprising an outer, vertically oriented cylinder (2) provided with means (5, 6) for supplying liquid to the outer cylinder (2). The liquid flows down through the cylinder (2) along its vertical shaft without being in contact with the inner surface of the cylinder (2). The apparatus is provided with a detector (7) for measuring the radioactivity in said liquid. There are means (3) for supplying a flushing liquid to the inner part of the cylinder (2) in such a manner that the flushing liquid flows downwards and forms a liquid film on the inner surface of the cylinder (2). The invention is characterized in that means (3) comprise at least one supply connection or supply pipe (21a, 21b) for supplying flushing liquid, which discharges somewhat above a column (16a) which runs along the inner surface of the cylinder (2) in order to produce said liquid film.
