Source-Dependent Probability Densities Explaining Frequency Distributions of Ambient Dose Rate in the Netherlands

Several sources and processes contribute to the natural radiation background level, causing significant fluctuations in time. Quantified knowledge on the probability of these variations is desirable for many reasons, e.g. to discriminate between natural and human-induced factors or to support the management of nuclear emergency networks. Frequency distributions of ambient dose rate, as observed by the Dutch National Radioactivity Monitoring Network over the period 1990-1994, have been explained through the joint contribution of five time-varying sources, including counting statistics.
