Abstract : A discussion is presented on the scaling of pressure-distance curves for a particular model of a nuclear explosion using an ideal-gas equation of state. A family of non-dimensional curves is presented which allows scaling to different ambient conditions for a given energy source. These curves also make possible scaling close-in to the initial fireball. It is shown that the theoretical point-source solution for an ideal gas agrees with the computed solutions, except at close-in distances and at shock strengths below 50. It is shown that neither of these ideal-gas solutions agrees as well with experiment as a real-gas solution.
