Abstract

PURPOSE: To facilitate measurement of the exposure does rate on the leeward ground surface, by measuring the exposure does rate in a limited space in the emission source side to obtain a 4π exposure does rate emission rate and average energy of radioactive rare gas.
CONSTITUTION: Radioactive rate gas generated from unclear reactor building 1 is exhausted to the environment from stack 2, and the exhaust rate of the stack is measured continuously by measuring equipment 3. A part of waste gas is flowed continuously to limited space 9 by pump 4, and detector 10 for exposure does rate measurement and detector 11 for γ-ray flux measurement are inserted to space 9. Detectors 10 and 11 are connected to differential amplifier 14 through logarithmic does indicator 12 and lograte meter 13 respectively. By this constitution, the exposure does rate on the leeward ground surface can be obtained easily by using the 4π radiation dose rate emission rate calculated from the exposure dose rate measured by detector 10 and average energy of nuclid mixture radioactive rare gas obtained from differential amplifier 14.
