What is ionizing radiation?
Ionizing Radiation800 Points
When these interact with the upper atmosphere, they create secondary
x-rays and subatomic particles.

Half-Life200 Points
An isotope’s half-life is the amount of time it takes for half of the atoms of an
isotope to decay into this.

Back to question board
What is 125 g?
Half-Life1000 Points
A radioisotope will continue to undergo radioactive decay until this
happens.
