How to talk about nuclear
In your career as a professional in the nuclear community, chances are you will, at some point, be asked (or volunteer) to talk to at least one layperson about the technology you know and love. You might even be asked to present to a whole group of nonnuclear folks, perhaps as a pitch to some company tangential to your company’s business. So, without further ado, let me give you some pointers on the best way to approach this important and surprisingly complicated task.

In this paper the transport of radiation in a half space, due to a source external to the medium, is analyzed. This situation arises in certain radiation transport studies. In particular, we compare, in the diffusion description, the correct two-dimensional solution with a commonly used series of one-dimensional approximations. The results should be of help in determining, for a given problem, whether a full multidimensional transport calculation is required or if the one-dimensional approximation is adequate. In the case of radiative transfer, it is shown that a one-dimensional treatment is in general not adequate.
