Discussion on short-lived radionuclide aerosol monitoring

Continuous radioactive aerosol monitors, or continuous air monitors (CAMs) are referred usually to the long-lived α/β nuclides (such as U, Pu and ¹³⁷Cs etc). Thus it has not considered the decay corrections of radioactive nuclides themselves during sampling and measuring. But it is important as well to monitor short-lived nuclides such as ⁸⁸Rb, ¹³⁸Cs and ¹⁸F, etc in many nuclear factories including nuclear power plants where the nuclear reactors are to be operated. Therefore, the monitoring of short-lived nuclides is important. This paper discusses the problems about the monitoring of short-lived nuclides, and suggests the data processing methods that can be used for the real monitors to obtain reasonable monitoring results of short-lived nuclides.
