On the Variance of a Product with Application to Uranium Estimation

Currently there are two methods used for estimating the amount of uranium in a container. One of these methods estimates the amount of uranium directly by certain N.D.A. techniques. The second method is to obtain estimates of both the weight of material in the container and the concentration of uranium in this material. These estimates of weight and concentration are then used to estimate the amount of uranium in the container. Regardless of the method used, uncertainties of estimates of the amount of uranium should be carefully studied.
