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
80
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
underground
A breeder reactor is designed to produce
plutonium
The number if nuclear weapons that the United States had was closest ti
ten thousand
PCR has been used to
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
PU-239
Which of the following is not a good example of the doubling law?
future population growth
The Canadian Candu reactors use
deuterium
Plutonium can explode with few generations that can uranium because
plutonium fission releases more neutrons.
In neutron power plant, the matieral that runs through the turbine is
steam
The number of deaths from the Nagaski bomb is estimated to be
50,000 to 150,00
The smallest container that could contain one critical mass of plutonium is
coffee mug
The bomb dropped on Hiroshima used as its fuel
uranium
Saddam Hussein planned to enrich uranium using
Calutrons
A centrifuge enrichment plant takes an area of about
one large classroom
PCR involves
DNA
One of the most dangerous radioactive matierals from fallout is
Sr-90
The term China Symdrome refers to
the meltdown of the nuclear fuel
Depleted uranium is a useful substance because
an artilery shell made from it is very penetrating
PCR was used to learn about
the descendents of Sally Hemmings
Another name for the H bomb is
thermonuclear bomb
A nuclear explosion similar to the one produced by North Korea would destroy
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
