Training Scientific visits Interlaboratory comparisons (ILC) Quality manual, documentation On going activities:

- DCA: ILC on 500 cells in collaboration with EURADOS- FISH : homogenity in the scoring process- MN: improuvent of the staining

Newly investigated

1 2 3 4 5 6 7Gene expression assay Telomere Centromereγ-H2AX foci analysis RAMAN spectroscopy

2 institutions trained

9 institutions trained

OSL: 5institutions trained

No training No training No training

OSL: several ILC. Electronic components: Difficulties to identify the relevant componentsEPR: variability of material response

Perform a standard ILC analysis and identify the parameters affecting the results

Image and slides sharing.Z test passed successfully for several set of samples

ILC on blood samples shipment not yet performed

Some good candidates have been successfully used in ILCEffect of transportation conditions tested

To be validated on in vivo exposed populations

Involved in a large ILCJust one lab performing the assay up to nowTwo doses out of 4 have been correctly estimated

Identification of the parameters affecting the resultsNew ILC with more labs involved

ILC carried out by dicentricscoring on images. Homogeneous results. Promising approach for highly accurate biodosimetry”

ILC on slides and blood samples to be performed.Standard Z test to be used
