It has been assumed for the distributed source
cons 1dereq in our methods, however, that such an effect is
not important.
It would be interesting to theoretically
verify this assumption.
We are therefore attempting to develop new approximate
methods or modify existing methods to predict the angular
distributions and energy spectra for various source distributions for a two media geometry such as the earth-air
situation.
Such methods would be useful not only for
environmental gamma radiation problems but also for solving
general shielding problems.
