In comparison with different measuring methods it turned out, that the experimental determined sensitivity had considerable fluctuations (up to 50%). After several neutron irradiations the bubble detectors showed a small gamma-sensitivity, however the gamma-rays formed significant larger bubbles. Photographs of the irradiated bubble detectors were taken in order to improve the accuracy enumerating a large quantity of bubbles. Then the photographs were evaluated in a densitometer. The measurement of neutron doses in the range from 0.01 mSv to 0.8 mSv is possible with a set of bubble detectors with different sensitivity.deBlasendetektorHe-3-proportional countersHe-3-Zählrohrneutron bubble detectorsneutron detectorsneutron dosimetryNeutronenNeutronendetektorenNeutronendosimetrieneutrons620Neutronenblasendetektoren-Zählrohre - Vergleichende Messungen mit schnellen NeutronenNeutron bubble detectors - measurements with fast neutrons in comparison with customary devicesconference paper
