Radon which occurs in
uranium decay series is a noble gas and it moves from the deeper layers of the
earth crust to the atmosphere. Formation of the radon gas in the Earth's crust
and its migration to atmosphere are quite complex process because of too many
factors. In this process, both the advection and diffusion are effective
mechanisms on radon transport. But mostly the dominant mechanism is diffusion.
In this study, radon diffusion of soils taken from Küçük Menderes Basin was
investigated by controlled laboratory experiments and the radon diffusion
coefficient of these soils were calculated
