|
What is photon?
Gamma radiation consists of a _______ that is released from the unstable nucleus.
|
What is proton?
When an isotope undergoes beta decay, the nucleus obtains a _________.
|
What is altered?

|
What is chain reaction?
A _____________ is a self-sustaining reaction in which the products of the reaction can initiate another similar reaction.
|
What is Cobalt-60?

|
What is radioactive decay series?
A ___________________ is when an isotope undergoes decay but the daughter nuclide is unstable so it continues to undergo decay until a stable state is reached.
