The first stage entails a detailed analysis of the situation in which persons are exposed, in order to determine who is exposed and where, when, and how the exposure occurs.


Identification of radiation protection options

This second stage consists in examining all the possible ways of reducing exposure by acting on the sources and/or protection system and/or length of exposure.


Quantification of the options

The third stage consists in evaluating the effectiveness of each option in terms of the exposure reduction and its cost.


Selection of the best option

During this stage, the options are compared so as to select the one which leads to the best compromise between exposure reduction and cost, using the reference monetary values of the man-sievert.


Sensitivity analysis

The aim of this final stage is to verify that the choice of option is sound.
