Abstract
A study was made of the air-ground correction factors for point isotropic gamma sources at source heights likely to be of interest for foliar retention problems. Infinite medium calculations of the exposure dose in air, or air-like materials, can be applied to problems involving elevated, uniformly distributed Gamma sources without introducing large errors. For individual elevated sources, the effects of the air-ground interface could be most pronounced. For many problems it should be possible to apply boundary correction factors for a source on the ground.
