Issues and practices in the use of effects data from FREDERICA in the ERICA Integrated Approach

摘要: The ERICA Integrated Approach requires that a risk assessment screening dose rate is defined for the characterisation within Tiers 1 and 2. At Tier 3, no numerical used, driven by methods can evaluate possible effects of ionising radiation on reproduction, mortality morbidity. Species sensitivity distribution has been used to derive predicted no-effect (PNEDR). method was based mathematical processing data from FRED (FASSET database merged with EPIC form FREDERICA) resulted in PNEDR 10 μGy/h. This assumed ascribe sufficient protection all ecosystems detrimental structure function under chronic exposure. value weighed against number points comparison: (i) values obtained application safety factor method, (ii) background levels, (iii) rates triggering radioactively contaminated sites (iv) former guidelines literature reviews. In analysis must be problem formulation thus highly case specific. Instead specific recommendations numeric values, guidance sorts may applied refined effect provided illustrated.
