Carbon dating nuclear chemistry
By 1898, Marie Curie found that compounds of thorium were also "radioactive." After pain-staking effort she eventually isolated two more radioactive elementspolonium and radiumfrom ores that contained uranium.
Within a few months, Henri Becquerel found that both uranium metal and salts of this element gave off a different form of radiation, which could also pass through solids.However, the principle of carbon-14 dating applies to other isotopes as well.Potassium-40 is another radioactive element naturally found in your body and has a half-life of 1.3 billion years.One, which he called alpha () particles, were absorbed by metal foil that was a few hundredths of a centimeter thick.
The other, beta (� particles, could pass through 100 times as much metal foil before they became absorbed.Many Christians have been led to distrust radiometric dating and are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent.
