Radioisotopes often emit alpha particles, beta particles, or gamma rays. The distance they travel through matter increases in or
der from alpha to gamma. Each radioisotope has a characteristic half-life, which is the time needed for half of a sample of radioisotope to undergo nuclear decay. Which quality is desirable for a radioisotope that is used for medical imaging of a specific organ
this is important since there are different electromagnetic waves used to observe different parts like some are used to detect tumours and growths and others fractures so to detect eg fractures the radiation must be highly penetrative to penetrate skin and flesh to reach the bones but it's half-life will
only matter when you look at environmental issues and stuff
