is a series of events, and each event is caused by the previous one

about one cup
The smallest container that could contain one critical mass of plutonium is:
-about one cup
-a large suitcase
-the trunk of an automobile
-a table spoon
neutron-induced fission
The foundation of nuclear weapons is:
-carbon-14 isotope
-boiling water that warms up nuclei
-powerful lasers
-neutron-induced fission
Because more neutrons are emitted in plutonium fission than in uranium fission.
The critical mass for a bomb based on uranium fission is different than that for plutonium fission. Why?
-Because they have different densities
-Because more neutrons are emitted in plutonium fission than in uranium fission.
-Because uranium is lighter than plutonium
-Because uranium is heavier than plutonium
uranium
The bomb dropped in Hiroshima used as its fuel:
-hydrogen
-uranium
-deuterium and lithium-6
-plutonium
a Pu-239 bomb
An implosion bomb is required for:
-a thermonuclear bomb
-a boosted fission weapon
-a U-235 bomb
-a Pu-239 bomb
fission fragments
The dangerous radioactivity in fallout comes from:
-neutrinos
-fission fragments
-neutrons
-gamma rays
steam
In a nuclear power plant, the material that runs through the turbine is:
-fission fragments
-electrons
-neutrons
-steam
the meltdown of nuclear fuel
The term China syndrome refers to:
-production of plutonium in China
-the accident at Chernobyl
-meltdown of nuclear fuel
-nuclear terrorism
strontium-90
One of the most dangerous radioactive materials from fallout is:
-plutonium-239
-deuterium
-uranium-235
-strontium-90
the nuclear reactor depends on slow neutrons
A nuclear reactor cannot explode like a nuclear bomb because:
-it is carefully designed to shut down quickly.
-it contains too much uranium.
-it contains no uranium.
-the nuclear reactor depends on slow neutrons.
underground
According to the textbook, the least bad place to put nuclear waste is:
-underground
-in our food
-in the Sun
-all the way into outer space
Pu-239
The material that might be “reprocessed” from nuclear waste is:
-Pu-239
-U-235
-U-238
-tritium
DNA
PCR involves:
-DNA
-carbon-14
-tritium
-heavy water
