Abstract

The low temperature liquid storage tank having crack-detecting means of the present invention is provided with at least a heat insulating layer and at least an impermeable layer applied to the inner wall of the tank shell in laminated relationship with each other. A plurality of hermetically sealed sources of radio-isotope are secured to the inner surface of the tank shell so that any crack in the impermeable layer, if such is generated, can be detected by detecting leakage of radiation from the sources through such a crack by a dosimeter.
