A Geiger-Muller tube detects radiations by absorbing the radiation and converting it into an electrical pulse which triggers a counter and is displayed as a count rate. ] Radioactive elements have a wide range of half life values.The release of radiation by unstable nuclei is called radioactive decay.This process occurs naturally and cannot be influenced by chemical or physical processes. Students not only want to know how old a fossil is, but they want to know how that age was determined.Some very straightforward principles are used to determine the age of fossils.
