PURPOSE:To especially detect and measure the neutron in applied radiation by irradiating the colored viscous particles settled in the calcium carbonate solution of a transparent container with neutrons and calculating the number of the floated particles at any time by the naked eye. CONSTITUTION:Viscous particles 2 are put in a transparent container 4 filled with an aqueous solution of calcium carbonate. When these particles 2 are irradiated with neutrons, the neutrons become gas bubbles 6 with a diameter of about 0.5mm to be accumulated in the fine viscous particles of calcium alginate and do not issue to the solution. The viscous particles 7 containing gas bubbles 6 are suspended in the solution to be accumulated in the upper part of the container 4. The amount of the floated viscous particles 7 is proportional to the amount of the neutrons applied to this detector. Therefore, by visually confirming the number of fine floated colored viscous particles 7 or the volume thereof from the graduations of the container 4, the amount of the neutrons applied to the detector can be known. When water is added to the container 4 to fill the same and a cap is applied to the container 6 to pressurize the container, an evaporated substance in an overheated state is liquefied to be capable of being reutilized.
