The objectives of this work were to study the distripution of certain nuclides within fall-out particles and to
determine some of tne differences in radiochemical properties
between Liquid and solid fall-out.

On account of a failure in
the tining circuit, the collector on Bokororyuru opereted before
the shot.
The collector on Enyu did not operate properly. Col-
lectors on Rukoji and Arriikan operated properly.
