Recent reports discussing the population bomb
indicate that the explosion is slowing
A one-kiloton nuclear weapon, exploded at ground level, would destroy
about 1 square kilometer of a city
For an atomic bomb, the number of doublings required is closest to
An implosion type bomb is required for
a PU-239 bomb
Moore's Law relates
computer chip capability
Which of the following does not represent exponential growth?
illness from anthrax
The statement that the Chernobyl accident will kill 24,000 people is based on
the linear hypothesis
A moderator is something that
slows neutrons
The dangerous radioactivity in fallout comes from
fission fragments
fallout is much worse if the bomb
is exploded near the ground
A nuclear reactor cannot explode like a nuclear bomb because
the nuclear reactor depends on slow neutrons
According to the text, the least bad place to put nuclear waste is

All anwsers
Hiroshima bomb was used for
gun design
If the water moderator is lost from nuclear reactor
the chain reactor will increase, causing a reactivity accident.
The matieral that might be "reprocessed" from nuclear waste is
Which of the following is not a good example of the doubling law?
future population growth
The Canadian Candu reactors use
Plutonium can explode with few generations that can uranium because
plutonium fission releases more neutrons.

the size of a college campus
Cold Fusion
has been seen in laboratory experiments
At Three Mile Island
some of the uranium fuel melted
What dishtinguishes a breeder reactor from other reactors is that
it makes more fuel than it uses
Jupiter is not a star because
it isn't massive enough
