2, Transport through and removal from the atmosphere
a, The stratosphere
(1) Transport, mixing, possible methods
of removal
(2) Storage time; cumulative world-
wide fallout as a fundtion of time;
predictions of future fallout from
single event; from past weapons
test
(3) Sources of information; measurements
and estimates of radioactivity
in stratosphere
b. The troposphere
(1) Tropospheric removal processes;
storage time
(a) Precipitation, interception,
dry deposition
(2) Possible regions of unusual removal
(fallout) because of meteorology or
topography
(a) Exposure to prevailing winds
and tne sjiatimes accompanying
effees, crograpnie rainfall
(b) Effect of large bodies of
water on the distribution of
fallout on adjoining land
areas
(3) Meteorological tracking and other
discussion of transport
