PURPOSE:To obtain measuring equipment of a radioactive substance released at an accident of a nuclear power plant which measures and displays automatically the released amount of the radioactive substance, by disposing a flow rate measuring device and a radioactive substance concentration measuring device in the vicinity of a blowout panel provided in the outer wall of a building and also by making them operate on the basis of an opening signal of the blowout panel. CONSTITUTION:Radioactive substance released amount measuring equipment 16 comprises vapor-air flow rate measuring devices 12 and 13 and radioactive substance concentration measuring devices 14 and 15 provided in the vicinity of blowout panels 10 and 11 provided in a reactor building 1 provided with a reactor, a turbine building 2 and the like in a nuclear power plant, and it receives, as inputs, opening signals of the blowout panels 10 and 11, flow rate signals from the vapor-air flow rate measuring devices 12 and 13 and concentration signals from the radioactive substance concentration measuring devices 14 and 15 and measures and displays the amount of a radioactive substance contained in vapor and air released from the building or the like through blowout panels 10 and 11 when the blowout panels 10 and 11 are opened, and others.
