UCLA scientific personnel obtain soil and plantsamples and
hunt and trap wildlife and rodents in fallout areas from the Test

Site out to about 160 miles.

They also study the distribution of

fallout particles of different sizes with the objective of provid-

ing information which can be used in the prediction, of fallout
patterns,

If fallout is recorded in areas Within California, Utah or

Nevada where crops are grown, samples of soil, forage crops,

_végetables and milk will be collected to learn more about the
biological availability of fission products,
Monitoring in Continental United States
Outside of the area within about 200 miles of the Test Site,

monitoring activities are conducted in cooperation with the U. S.

_ Weather Bureau, the U. S. Public Health Service, and 11 Atomic

Energy Commission installations.

These operations are not conducted

in the expectation of possible hazard, but for scientific purposes
and to keep the public informed on levels of radioactivity.
As in past test series, a network of U. S. Weather Bureau

stations collects dust samples.

The stations expose sheets of film

covered with adhesive outdoors on a tray each for 24 hours, and then

mail them to the Commission's Health and Safety Laboratory in New
York. There, the samples are reduced to ashes and the radioactivity
measured with extremely sensitive instruments,
Ninety-three Weather Bureau sampling stations are in operation

during Operation Plumbbob,
