The report gives results of a characterization of radon generation and transport in Florida concretes sampled from 12- to 45-year-old residential slabs. It also compares measurements from the old concrete samples to previous measurements on newly poured Florida residential concretes. Radon generation in the aged slabs was characterized in terms of concrete radium concentrations and radon emanation coefficients, and radon transport was characterized by radon diffusion coefficients and air permeability coefficients. On the average, these values are about a factor of 2 higher than average values for new residential concretes. The measured air permeability coefficients also average about a factor of 2 higher than those for new concretes.
