Radioactive dating works best with what type of rocks - Does carbon dating prove the earth is millions of years.


The methods work because radioactive elements are unstable, and they are always trying to move to a more stable state. So, they do this by giving off radiation. This process by which an unstable atomic nucleus loses energy by releasing radiation is called radioactive decay . The thing that makes this decay process so valuable for determining the age of an object is that each radioactive isotope decays at its own fixed rate, which is expressed in terms of its half-life. So, if you know the radioactive isotope found in a substance and the isotope's half-life, you can calculate the age of the substance.

By the mid- to late 1800s, geologists, physicists, and chemists were searching for ways to quantify the age of the Earth. Lord Kelvin and Clarence King calculated the length of time required for the Earth to cool from a white-hot liquid state; they eventually settled on 24 million years. James Joly calculated that the Earth’s age was 89 million years on the basis of the time required for salt to accumulate in the oceans. There were other estimates but the calculations were hotly disputed because they all were obviously flawed by uncertainties in both the initial assumptions and the data.

Rosatom, Russia's state nuclear company, said in a statement to The Telegraph on Tuesday there had been "no unreported accidents" and the ruthenium-106 emission was "not linked to any Rosatom site". Its Mayak facility, where an explosion in 1957 contaminated a swath of central Russia, told state news agency RIA Novosti that it had not processed nuclear fuel with ruthenium-106 this year.
