  1. Influence of various room parameters upon radon daughter equilibrium indoors.

    Article - En anglais

    The parameters such as ventilation rate, attachment rate to aerosols and deposition processes, which influence the radon daughter equilibrium indoors, are discussed and the validity of the theoretical model checked by experiments.

    In agreement with the model calculations, the experimental data show, that the equilibrium factor F in rooms is mainly influenced by the rate of attachment to aerosols and the plateout of radon daughters.

    The equilibrium factor varies between 0.3 and 0.4 at an attachment rate of 300 h-1.

    The influence of ventilation upon the free fraction of RaA (218Po) - atoms is also investigated.

    This is in good agreement with the results of the measurements carried out in different types of rooms at the University Campus of Rahshahi.
