Generalized evaluation of environmental radioactivity measurements with UncertRadio : Part 1: Methods without linear unfolding

It is shown how a generalized evaluation of a large variety of environmental radioactivity measurements, without and with using linear unfolding, can be performed with a single program, Uncert Radio(UR). Using a function parser allows deriving numerical partial derivatives for ISOGUM compatible uncertainty propagation. The evaluation within UR is extended to include ISO 11929 decision thresholds and detection limits. Alternatively, propagation of distributions with MC simulation is included. Part I gives an overview considering evaluations without using linear unfolding.
