She did pioneering work with radioactive substances.
Radioactive dating works best with igneous rocks, particularly those formed from the cooling of molten lava or magma. This is because the mineral crystals in igneous rocks lock in the radioactive isotopes when they form, providing a reliable record of the time that has passed since the rock solidified. Sedimentary rocks are generally less reliable for radioactive dating due to their mixture of different rock fragments.
Radioactive dating works by measuring the amount of radioactive isotopes in a rock or fossil and calculating how long it has been decaying. By comparing the ratio of radioactive isotopes to stable isotopes, scientists can determine the age of the sample.
The method used will be determined by the rock type, but the age of a rock will be determined by a determination of the amount of decay of a radioactive isotope, either contained in the rock, or in a geologic layer of rock coinciding with a fossil.
You can date rock layers by radioactive dating using half-life in the igneous rock layers that contain radioactive isotopes like uranium or potassium. These isotopes decay at a known rate to stable daughter isotopes, allowing scientists to determine the age of the rock based on the ratio of parent to daughter isotopes present. Sedimentary rock layers cannot be dated directly using radioactive dating due to the possibility of contamination and the absence of radioactive isotopes in the rock itself.
A radioactive rock is one which contains traces of radioactive isotopes. These isotopes release radiation in its various forms. Any rock can be radioactive, but in particular igneous rocks tend to have radioactive properties. This is because they may have radon gas trapped in their crystals, which, under pressure, is released (this is why radon gas is used as an indicator of an upcoming earthquake). Radon gas is radioactive, and this causes the rock to be radioactive also.
Radioactive dating of rock samples determines the age of rocks from the time it was formed. Geologist determine the age of rocks using radioactive dating. The radioactive dating relies on spontaneous decomposition into other element. The spontaneous decomposition is called radioactive decay.
Yes, there are a number of uses for radioactive material. It depends on the type of radioactive material.

Plutonium is an artificial, radioactive metal.
Absolute dating is a radioactive isotope the geologist can use to learn the exact age of the rock.
