Analysis of quasicontinuous radon monitor response.
Continuous radon monitors respond quickly to changes in radon concentration but bear uncertainties due to the fact that the radon concentration in the detector changes within a counting interval. This disadvantage can be overcome by applying quasicontinuous sampling, where the detector chamber is sealed after the sample has been drawn, so that the radon concentration does not change while counting. The chamber is usually kept closed for 15 min or longer and subsequently flushed or evacuated before the new sample is taken. This paper presents a forward-marching algorithm suitable for the analysis of the response of quasicontinuous radon monitors. The method can be used to obtain both 222Rn and 220Rn concentrations in the gas sample.
