Which of the properties of radioisotopes make them useful as tracers in medical or agricultural applications? i. their chemical behavior is the same as nonradioactive isotopes. ii. they emit various types of radiation. iii. the nuclear reaction is unaffected by the chemical state of the isotope.

ii) They emit various tyoes of radiation

Explanation:

They fact that they emit radiation makes them ideal to use as a tracer because that radiation can be detected and followed. This means that you can know where the isotope is going throught.

Cause of that, radioisotopes are very helpful in medical applications such as tracing blood veins.
