ABSTRACT<br />

The data for gummed film fallout measurements through December 1959<br />

are reported. While the initial purpose of the gummed film network was to<br />

determine the geographic distribution <strong>and</strong> time of arrival of fallout, con-<br />

| siderable effort has "been devoted to computation of strontium 90 deposition<br />

_ <strong>and</strong> infinity gamma dose. These latter computations have "been satisfactory<br />

~ for the period of observation <strong>and</strong> furnish data for locations not covered by<br />

B other types of measurement.<br />

Detailed comparisons are made between strontium 90 estimates from<br />

| gummed film <strong>and</strong> analyses made on pot <strong>and</strong> soil samples* Comparable tests<br />

_ of the gamma dose estimate are not possible.<br />

The bulk of the report consists of summary tables for each gummed<br />

film station listii^g the monthly estimates of strontium 90 deposition <strong>and</strong><br />
