ANNOUNCEMENTS

Sound recordings of the oral presentations at this Second World Conference on Neutron Radiography are available. For purchase please contact Mr. J.-L. Person (CEA-CEN Saclay).

Next Conference The next Conference will probably be held in 1990 in Japan (see closing remarks).

ACKNOWLEDGEMENTS

Special thanks are due to Mr. lean-Louis Person and Mr. Heinz Rottger, the joint secretaries of this conference, for the excellent organizational work in arranging this conference and the publication of the proceedings.

Special thanks are also due to the many hard working members of the host committee in Paris, and particularly to Mrs. Colette Paris, Fran~oise Prudon, Martine Chmiel and Mr. Roger Ponsot, whose kindness and effectiveness might have been appreciated by everybody.

Last, but not least, thanks are due to the authors and participants, many of whom travelled large distances to this information exchange.
