ABSTRACT:
The invention relates to the detection of very small gas leakages through liquid seals around a passage, which seal may be situated around a shaft.
Before it was not easy to detect gas leakages to the environment through liquid seals from radio actively contaminated spaces.
Said disadvantage can be avoided, by determining the gas leakage to the environment through a liquid seal by applying at one side of the seal a gas activable by neutrons and subsequently determining the concentration of the said gas in the sealing liquid as function of the time.
