However, many objects were found in caves, frozen in iceor in other areas whose ages were not known; in these cases, it was clear that a method for dating the actual object was necessary. Inthe Radiocarbon dating is based on the decay of chemist Bertram Boltwood — proposed that rocks containing radioactive uranium could be dated by measuring the amount of lead in the sample. Polskie filmy archiwalne online dating All rights reserved.

This was because uranium, as it underwent radioactive decay , would transmute into lead over a long span of time. Thus, the greater the amount of lead, the older the rock. Boltwood used this method, called radioactive dating , to obtain a very accurate measurement of the age of Earth. While the uranium-lead dating method was limited being only applicable to samples containing uranium , it was proved to scientists that radioactive dating was both possible and reliable.
