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.
What else can I help you with?
Radioactive dating of fossils depends on the decay of what?
Radioactive dating of fossils depends on the decay of isotopes, such as carbon-14 or uranium, within the fossil. By measuring the amount of remaining radioactive isotopes and their decay products, scientists can determine the fossil's age.
What must be true for a fossil organism to be useful as a index fossil?
The absolute age of the index fossil was determine by radioactive dating or another absolute method
What type of rock does radioactive dating work with?
Rocks in general are not dated, but a fossil would be.
Is gasoline radioactive?
Oil is not generally radioactive unless it was originally located near radioactive material when it was extracted. More often, it only becomes radioactive when exposed to or stored near radioactive materials post processing.
Radioactive dating works best with what type of rocks?
Rocks in general are not dated, but a fossil would be.
Are fossil fuels radioactive?
No, fossil fuels are not radioactive. Fossil fuels like coal, oil, and natural gas are formed from the remains of plants and animals that lived millions of years ago. Radioactive materials are not part of the formation process of fossil fuels.
Pollutant not created by fossil fuels?
One example of a deadly pollutant not created by fossil fuels is highly toxic radioactive waste, which is the bi-product of using radioactive isotopes.
What is another way to age a fossil?
By radioactive decay process.

The absolute age of the index fossil was determine by radioactive dating or another absolute method
What plants have radioactive waste?
All plants have radioactive waste, especially fossil fuel plants.
How old is a fossil that has one sixteenth of the radioactive carbon found in living organisms according to carbon dating?
This fossil has 23 000 years.

Used to date fossils in rocks to give an approximate age?
Radiometric dating is used to determine the age of fossils in rocks by measuring the decay of radioactive isotopes, such as carbon-14 or uranium-238, in the fossil. By comparing the amounts of the parent and daughter isotopes present in the fossil, scientists can calculate the age of the fossil. This method provides an approximate age of the fossil based on the rate of radioactive decay.
