title: Airborne 222Rn concentration in an Egyptian village.
abstract: The indoor radon concentration in a typical Egyptian village in Delta was measured in 50 houses during summer 1999 and winter 2000. This survey was done using three different types of charcoal canisters: 4" open-faced, 2.75" open-faced, and 2.75" diffusion barrier. The average winter to summer ratio was 2.1 and 1.2 for open rooms and closed rooms, respectively, in clay buildings, while it was 0.8 and 1.0, respectively, in concrete buildings. The seasonal variations of radon concentration as well as the effect of building materials were discussed.
