radiation decay
What is radiation decay?
The process by which an unstable atomic nucleus loses energy by emitting radiation.
Which of the following is NOT a common type of radiation emitted during decay?
Ultraviolet radiation
What particle is emitted during alpha decay?
A helium nucleus
Which of the following best describes beta decay?
The conversion of a neutron into a proton and electron, with the electron being emitted.
What does the term half-life refer to in radioactive decay?
The time it takes for half the atoms in a radioactive sample to decay.
What is the main danger of gamma radiation?
It can ionize cells and cause damage to living tissue.
During which type of decay does a neutron turn into a proton?
Beta decay
Which best defines a radioactive isotope?
An atom with an unstable nucleus that emits radiation.
Which unit is commonly used to measure the activity of radioactive decay?
Becquerel
When a radioactive isotope decays, what happens to its atomic number?
It increases or decreases depending on the decay process.
