Each radioactive element has its own rate of decay, which has been established in laboratories.The key to radiometric dating is that radioactive isotopes normally decay at a precise rate and the time they take for half of the atoms to decay is known as the half-life. The results on different samples gave ages between .35 ( /- .05) and 2.8 ( /- .6) million years. The fact that accepted, “scientific” dating methods failed to assign the correct age to the rocks should cast doubt on the ages assigned to rocks of unknown age. Mark Isaak, on the website, Talk Origins, said: Briefly, Steve Austin collected a sample from the Mount St. Because of its size and occurrence in our lifetimes, it's been the subject of much scientific inquiry. Steven Austin, a creationist and Ph D geologist, collected rock samples formed in the eruption and had them tested using the potassium/argon dating method.Furthermore, many geochronology laboratories do not have the expensive state-of-the-art equipment to accurately measure argon in samples that are only a few million years old." This is a real problem for evolutionists.1) If a rock of unknown date tests to be 3 million years old, how can we be sure it's not only 50,000 years old?Isotopes are atoms of the same element which vary by the number of neutrons in their nucleus.Some isotopes have so many neutrons that the nucleus is unstable and reduces its size by releasing either alpha or beta particles or gamma rays.
There is no absolutely reliable long-term radiological clock. The age of any fossil can never be measured directly, only indirectly with large assumptions being made and almost entirely dependent on the discover’s world view.The cartoon to the right, compliments of Answers in Genesis, makes the point rather sarcastically.Evolution requires eons of time, hence the inundation of long ages in everything we see and read; millions and even billions of years.Half-lives can vary from fractions of a second to millions of years for different isotopes.The element that decays is called the parent and the element into which it breaks down is called the daughter.
