Radiation
This is the process in which an unstable nucleus emits charged particles and energy
Radiation
Unlike chemical reaction nuclear decay rates are
constant
These are the three types of particles used to bombard atomic nuclei with to transmutate atoms
protons, neutrons and alpha particles
In nuclear reactions this is converted into energy
mass
Blocking this type of radiation will likely also allow you to block the other two types
gamma
These are isotopes that are radioactive.
Radioisotopes
Carbon-14 cannot be used to date materials older than this
50,000 years
One purpose of collision experiments is to sudy this
atomic structure
This force works on both protons and neutron.
strong nuclear force
When nuclear radiation enters the tube of this device it ionizes the atoms in the gas
Geiger counter
This type of nuclear decay releases energy but not a particle
gamma decay
The half-life of tritium, or hydrogen-3 is 12.32 years. After about 40 years this much of a sample of tritium will remain.
one-eighth
Transmutation involves this type of change
Nuclear change
The fusion of these two particles will create an isotope of berilium-8 and a large amount of energy
Helium-4
This is thought to be among the smallest basic units of matter
Quark
This type of radiation is emitted when Uranium-238 forms Thorium-234
Alpha
This particle has no mass and a charge of +1
Positron
Creating a larger nucleus in an atom is the definition of this term
Transmutation
This is used to cool the steam in the turbine chamber of a nuclear reactor
Water
The first artificial transmutation converted this isotope into oxygen-17
Nitrogen-14
Carbon-14 will become this during beta decay.
Nitrogen
Radiocarbon dating uses this to compare the amount of Carbon-14 left in a sample to.
Carbon-14 levels in the atmosphere
Transuranium elements have an atomic number larger than this
92
These reactors require mor energy and therefore are not utilized in nuclear power production
Fusion
This is the smallest possible amount of a fissionable material needed to sustain a nuclear chain reaction
critical mass
