The requirement for an activation of P is a measurement that shows no contamination. Such measurements trigger the decrease of the measurement time based on the conditional probability defined in DIN 25482/1.

    Basic Principles and Methods RTM614 Measurement Method 12.2.9 Units The software is able to present the measurement result in the physical units counts per second (cps), Becquerel (Bq), decays per minute (dpm) and Nanocurie (nCi). Except for cps a calibration and therefore its factor is required to calculate the respective value in the unit selected.
