“…However, we can obtain a great deal of understanding about bounding calculations, un certainty, and sensitivity by using simpler mod els. 2,25 " 27 While these simpler models n.sy be only qualitatively correct, relative measures of risk may be readily ascertained.…”

“…MISER uses Monte Carlo techniques where appropriate. The modeling of MISER transport phenomena differs from that for either NUTRAN 25 or NWrT. …”

“…Human doses will depend on the movement of waste to wells or surface waters, the concentration in the ecosys tem, human diets and living habits, and the bio chemistry of the waste nuclides in the human body. These factors are modeled in the BIODOSE code 25,32,34 to produce a set of tables rytj) for use in Eq. (27) in the manner described previously.…”
