Dynamic Assessment of Radon Source in Buildings, Based on Tracer Gas Experiment Statistical Modeling

Popis výsledku v původním jazyce

In this paper, we describe an improved dynamical model for assessment of radon source in a building taken as a single compartment. The data upon which the model operates consist of typical outcomes of a tracer experiment ? that is of simultaneously measured concentrations of radon and tracer gas concentrations (they do not have to have the same time resolution, however). The model has time-varying coefficients and it is casted as a state-space model. Hence, it allows for essentially non- or semi-parametric estimation of time-varying radon entry rate (RER) and air exchange rate (ACH) based on (extended) Kalman filtration. The state space model is carefully formulated so that it produces more or less automatically not only point estimates of both RER andACH, but also their confidence intervals and/or test of various practically interesting hypotheses, including those related to the radon remedial action limits violations. Compared to our previously published work, the model explicitly a
