IPC Unit 3 Nuclear Reactions Learning Statements
Question | Answer |
---|---|
Two types of nuclear reactions | fission & fusion |
can be used to produce energy and to conduct medical tests | nuclear reactions |
reactions that split the nucleus of an atom; when a isotope is bombarded with high speed particles to split the atom | fission |
reactions that join two smaller nuclei to make an atom with a larger nucleus; two low mass isotopes join together under extreme pressure and temperature | fusion |
type of reactor that currently requires more energy to force atoms together than the energy that is produced | fusion nuclear reactors |
currently rely on fission reactions to produce high amounts of energy | nuclear reactors |
What type of reaction occurs on the sun and produces large amounts of energy? | fusion nuclear reactions |
What removes excess heat from the reactor core of a nuclear reactor? | coolant |
_______________ can be alpha particles, beta particles, or gamma rays. | radiation |
Nuclear medicine imagining uses radioactive tracers that are swallowed or injected into the patient and emit _______________. A gamma camera detects the gamma rays and creates an image of the function of the organ. | Gamma ray radiation |
What is an example of fission nuclear reactions used in medicine? | Fast Neutron Therapy |
What type of scans emit gamma radiation that is released by a fission reaction? | PET Scans |
What are atoms with the same number of protons but different numbers of neutrons? | isotopes |
What is the excess energy released by unstable atoms becoming stable? | radiation |
Atoms undergo fission --> makes heat --> turns water to steam in a turbine --> turns the turbine --> generates electricity | how nuclear reactors produce energy |
Is energy released or absorbed during nuclear reactions? | released |
What type of nuclear reactions release radiation? | fission and fusion |
