SECTION II
• MONTHLY SUMMARIES FOR INDIVIDUAL STATIONS
• Because of the change in emphasis for different test series and be
cause of differences between Nevada Tests and Pacific and Foreign Tests 9
the
• network has been subject to considerable change over the years. The majority
of the data presented are for sampling stations which have had a continuous
^
M
history since the end of 1952 when the first world-wide network was established.
Some stations entering the network later, particularly those set up in coopera
tion with the U, N. Scientific Committee on the Effects of Atomic Radiation,
• are also included.
Stations having data for only limited periods are not listed.
These
would include:
1. Special stations operating for short periods of time around the two
United States test sites.
I_ 2. Certain stations operating in cooperation with the U. S. Public
• Health Service.
3. Other stations not forwarding samples on a continuous basis.
• A map of the network is given in Figure 2, The stations operating
• directly with HASL (Table 13) are distinguished from those operating through
the United Nations Scientific Committee (Table 14)*
Table 15 is made up of
• the summary tables for all stations in order of station number.
In all of the summary tables, composite samples are marked with a
9 single asterisk (*). Where geographical interpolation was required to fill
« out a table, the values are marked with a double asterisk (**).
