3
Assessments are being done – little formal training available - so we don't assume much prior knowledge We are being asked for advice on use of assessment tools The tools are only recently developed and there are various complexities and assumptions which need to be understood www.radioecology-exchange.org
4
Some tools freely available and usable by others Focus here on ERICA Tool (and its Integrated Approach) developed by EC consortium RESRAD-BIOTA and R&D 128 mentioned when they have features not present in ERICA Tool www.radioecology-exchange.org EPIC FP4 FASSET FP4 ERICA FP5 PROTECT FP6

7
Many approaches use a tiered assessment structure (in common with other areas of risk assessments) simple initial screening progressing to more refined assessments if needed Also referred to as: staged or graded approaches
