Abstract
This note reports radon gas pore diffusion coefficient measurements fo r residential concretes from Florida, ranging in age from 12 y to 45 y . The coefficients ranged from 1.5 x 10(-7) m(2) s(-1) to 5.5 x 10(-7) m(2) s(-1). On the average, these values are about a factor of 1.6 hi gher than average values previously reported for new residential concr etes in Florida.
