A better model? Low levels of radiation and health effects
One of the more pivotal issues in facilitating the use of radiation sources—including nuclear power—in the United States (and most of the Western world) is concern about the health effects of low levels of radiation. The current regulatory assumption is that every additional increment of radiation linearly increases the risk of cancer.

Embedded in multidimensional nodal transport computations is the solution of transverse-integrated one-dimensional transport equations. Since, in these embedded one-dimensional computations, fluxes on boundaries are double P1 (DP1), it is generally assumed that the one-dimensional solutions, in the small-mesh limit, approach DP1 solutions. It is shown that this is not necessarily true. Small-mesh limits of nodal equations are derived, and it is shown that these are substantially worse than the DP1 equations under certain circumstances. Alternative nodal equations (which do have a DP1 small-mesh limit) are proposed.
