Abstract: The article presents a model for simulation of changes over time in the activity concentration of radon and thoron, and their progeny in an open system. The open system means the stream of radon, thoron, and their progeny can flow into space, and a defined air stream can come outside. In this sense the system can be treated as open. It was also assumed that inside the space may be operating devices equipped with a filtering system, which will reduce the concentration of radon and thoron decay products. Therefore, these assumptions correspond to a situation when in an flow-through chamber, calibration of the devices for the radon or thoron exposure monitoring is carried out, where nuclides are supplied from an emanation or flow through sources inside or outside, but also to spaces in an environment where the source of nuclides is, for example, radon and thoron exhalation, and air stream which flows inside and outside the space. The differential equations were formulated with the assumption that the concentration of radionuclides of concern in space is or became uniform. The equations do not consider possible losses due to diffusion, as well as inertial or gravitational deposition of aerosols.
