METHOD OF CONTINUOUS RADON MEASUREMENT : Response characteristics of scintillation cell and its application to continuous radon measurement

Abstract

Scintillation cell is a suitable monitor for continuous radon measurement. But it has an undesirable characteristics for measurement of rapidly varying radon concentrations because the response of the monitor is late about 3 hours. Then the measured values must be corrected to get the real concentrations. We made a mathematical model to simulate the response of scintillation cell, and developed the method to identify the five parameters involved in the model to estimate real values using measured data. The validity of the model was proved experimentally.
