A correlation of the in-containment monitor reading and airborne radioactivity within containment is useful in assessing radiological consequences of postulated power plant accidents. One accident of concern in the loss-of-coolant accident. A design-basis release from the core to the containment can be postulated and a time-dependent in-containment monitor response due to direct radiation can then be calculated using a fast-running point kernel code, but this calculation provides no estimate of wall-scattered radiation. The question presently addressed is the following: Is the wall-scattered radiation of sufficient importance to preclude use of the point-kernel method in this calculation. This study shows that a point kernel code can be used to calculate in-containment dose rates with errors of <30%.
