A radionuclide radioactive nuclide radioisotope or radioactive isotope is an atom that has excess nuclear energy making it unstable this excess energy can be used in one of three ways emitted from the nucleus as gamma radiation transferred to one of its electrons to release it as a conversion electron or used to create and emit a new particle alpha particle or beta particle from the.
The real heart of the ageoftheearth debate if debate is the right word is always radiometric dating there are lots of ways to guesstimate ages and geologists knew the earth was old a long time ago and i might add that they were mostly christian creationist geologists but they didnt know how oldradiometric dating actually allows the measurement of absolute ages and so it is.
Heroes and villains a little light reading here you will find a brief history of technology initially inspired by the development of batteries it covers technology in general and includes some interesting little known or long forgotten facts as well as a few myths about the development of technology the science behind it the context in which it occurred and the deeds of the many.
Carbon dating is used to determine the age of biological artifacts up to 50000 years old this technique is widely used on recent artifacts but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old.
nuclear chemistry is the study of the chemical and physical properties of elements as influenced by changes in the structure of the atomic nucleus.
quaternary quaternary in the geologic history of earth a unit of time within the cenozoic era beginning 2588000 years ago and continuing to the present day the quaternary has been characterized by several periods of glaciation the ice ages of common lore when ice sheets many kilometres thick have.
Clear physical evidence of the existence of the little ice age and themedieval warm period claims to the contrary are false.
The following material has been taken from a sheet entitled several faulty assumptions are used in all radiometric dating methodscarbon 14 is used for this example which was put out by dr hovind dr hovind r1 the atmospheric c14 is presently only 13 of the way to an equilibrium value which will be reached in 30000 years this nullifies the carbon14 method as well as demonstrating.
