[F1C. Methodology U.K.

C.3. Steps in the e.r.a. U.K.

3. Exposure characterisation U.K.

The likelihood or probability of each identified potential adverse effect occurring shall be evaluated to provide, where possible, a quantitative assessment of the exposure as a relative measure of probability, or otherwise a qualitative assessment of the exposure. The characteristics of the receiving environment(s) and the scope of the notification shall be taken into consideration.

Where the evaluation is expressed in qualitative terms, a categorical description ( high , moderate , low or negligible ) of the exposure shall be used and an explanation of the scale of effect represented by each category shall be provided.]
