Leon Mcintosh · Answer 1

That would be to find the age of the fossil. Its called radiometric dating.

Georgia Mathis · Answer 2

To find the age of the fossil

Step-by-step explanation:

You measure the intensity of the radiation (counts per minute) from a given mass of the sample.

If you know the half-life of the radioactive isotope (e. g., carbon-14), you can work backwards and calculate the number of years since the organism died.

A is wrong. You use a balance to determine the mass of the fossil.

C is wrong. The level of radiation tells you nothing about the species of the fossil.

D is wrong. You use a radiation detector to determine if a fossil is radioactive.
