Description

Since April 1988, a German nuclear power plant has used a new type of contamination monitor which allows the limit of 0.37 Bq/cm2 to be monitored within a measuring period of 20 seconds also for contaminations by EC emitters. The monitor consists of 5 Xe-gas filled large-area proportional counters operating in a spectroscopic modus (FAG Kugelfischer). (orig./HP)

Abstract (German)

Seit April 1988 befindet sich in einem deutschen Kernkraftwerk ein neuartiger Kontaminationsmonitor im Einsatz. Herzstueck der Anlage sind fuenf permanent mit Xenongas gefuellte Grossflaechen-Proportionalzaehlrohre, die in einem spektroskopischen Modus betrieben werden (FAG Kugelfischer). Sie ermoeglichen die Ueberwachung des Grenzwertes von 0,37 Bq/cm2 auch fuer Kontaminationen mit EC-Strahlern innerhalb einer Messzeit von 20 Sekunden. (orig./HP)
