This is a section on possible uczs cf radioactive matcrials
in the study of the science of meteorology.
Natural radon gas
in the air can be helpful in understanding verticle movements of
air from the land,
Weapons tests have taught much with respect
to lateral spread of air masses at various altitudes - how vain
scavenges the atmosphere of particles - the rate of transport
from the stratosphere to the troposphere and the removal time
for water from the atmosphere,
Experiments could be conducted
using introduced radioactive materials under controlled conditions
to study air flow and diffusion rates, hydrometeorology, L.G@ey
condensation, precipitation and evaporation,
and to study
electricity of the atmosphere especially the possible relationship
of electrical fields to the weather,
As to effects of nuclear weapons testing on the weather
the committee stated:
1, Nuclear Weapon debris was not effective as a seeder
for rain,
2. The amount of ionization produced is insignificant
in meteorological terms,
3, There has been no measurable decrease in the amount
of direct sunlight reaching the earth Whereas volcanoes
have been knovwm to decrease it by as much as 10-20% fcr
appreciable periods of time,
4, The apparent recent increa.
