How does the presence of the radioactive isotope Lead - 210 prove that an art forgery is fake?

• Lead - 210 breaks down too fast to be on an old painting

• Artists used to have to make their own paints from plants and dirt, etc...

• It emits light for a short time after a UV light is used on it

• It emits light for a ling time after a UV light is removed
