Abstract: 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.

Key words: short-lived nuclides, monitor, decay corrections, math derivations
