Method of dating fossils by radioactive decay holly marie combs brian krause dating
(These are the moving particles which constitute the radioactivity measured by Geiger counters and the like.) The end result is stable atoms, but of a numbers of protons and electrons.
This process of changing the isotope of one element (designated as the parent) into the isotope of another element (referred to as the daughter) is called radioactive decay.
This is done by chemical analyses in specially equipped laboratories with sophisticated instruments capable of very good accuracy and precision.
So, in general, few people quarrel with the resulting chemical analyses.
Thus, the parent isotopes that decay are called radioisotopes.
Actually, it isn’t really a decay process in the normal sense of the word, like the decay of fruit.
Thus, geologists refer to uranium-lead (two versions), potassium-argon, rubidium-strontium, or samarium-neodymium dates for rocks.The daughter atoms are not lesser in quality than the parent atoms from which they were produced.Both are complete atoms in every sense of the word.Note that the carbon-14 (or radiocarbon) method is not used to date rocks, because most rocks do not contain carbon.Unlike radiocarbon (Sm)—are not being formed today within the earth, as far as we know.
