stations established on islands within a radius of 2,000 niles of
Christmas Island. | In the island network, four were primary ate-
tions located on populated islands, manned by officers of the
U. S. Public Health Service; six were secondary stations Located
on more distant islands and populated mainly by JTF-8 personnel |
Who operated the monitoring equipment; nine were backgroundstations located on islands at a considerable distance from the test
area.
The equipment at the background stations consisted prima- |
rily of contimious background recording equipmerit operated by
weather groupe or scientific personnel already on the island.
Figure 1 shows the location and level of effort of the stations
of the network.

Environmental samples were collected routinely by JTF-8 per-
sonnel during the period of April 12-August 15, 1962.
Scientific
personnel aboard the C.F. Gilbert participated in this environmental sampling program on three cruises, April 2k -May 12, 1962,
June h-June 25, 1962, and July 23-August 15, 1962. Approximately
8,000 samples were collected, most of which were returned to the
University of Washington, Seattle, Washington, for camplete
analysis.
Data from these examinations will not be available un-
til after January 1, 1963.
