Submitted by Ruth Tinnacher on
Very interesting presentation. Could you please comment on how the mineralogical/structural differences you found between these two particles could affect the mobility of U and Pu in the environment? Thanks.


Submitted by Laura Kennell-Morrison on
From where were these particle samples collected? Geographic location is clear, but are these particles found within the local soils and waters in the area (based on the photo on the final slide, that was my interpretation)? Following up on the question above from Ruth, would be interested to know what the environmental health implications are, as they relate to the longevity and small size of these particulates (are studies underway, potentially using these findings, to characterize behaviour and distribution in the natural environment).


Submitted by Xiaofeng Guo on
Quite a surprising discovery of the Bruce particles! Since Al is quite abundant, any evidence of the XRD peak could associated with Pu aluminate perovskite phases. Also, did you see any silicon content in the EDX while Pu-U silicate (coffinite like) may also be possible?
