EFFECTS GROUP
Outline of Working Plan
1) UPDATE Dose-Effect DATABASE (11; A. Real; Spain; July ‘09)
( UNSCEAR; post 2006; Russian/Ukrainian)
2) DOSE – RESPONSE Relationships (13; J. G-L; IRSN; July ’11; PROTECT)
Species Sensitivity Distributions (acute vs chronic; field- vs lab-derived;
at various taxonomic levels)
3) Incorporate POPULATION MODELS (9; T. Sazykina; Russia; Jan. ‘11)
(Review existing models; life history data; data analyses)
4) Alternative Approaches (9; T. Sazykina; Russia; Jan. ’11; ICRP comm. 5)
(will non-parametric and Bayesian methods produce screening levels similar to SSD?)
EFFECTS GROUP
Outline of Working Plan
5) Multiples Stressors (13; H. Vandenhove; Belgium; Dec. ’10; IUR)
(Review literature; chemical industry; report on applicability to IAEA; collaborative exp.)
6) Canadian Benthic Data (4; S. Mihok; Canada; July ‘09)
(Uranium mining; derive dose to benthos; multivariate stats)
7) Develop and Publish Guidance Documents (21; T. Hinton; France; July. ‘11)
(Documentation of methods to derive screening levels; guidance on use of screening
levels; guidance in conducting effects type research)
8) Final Reports to IAEA (21; T. Hinton; France; Jan. ‘12)
