#:"One type of nuclear decay is the emission of Helium nuclei known as an alpha emission. Elements like uranium and thorium produce helium in zircons as a by-product of their radioactivity. This helium seeps out of (sic) zircons quickly over a wide range of temperatures. If the zircons really are about 1.5 billion years old (the age which conventional dating gives assuming a constant decay rate), almost all of the helium should have dissipated from the zircons long ago. But there is a significant amount of helium still inside the zircons, showing their ages to be 6000 +/- 2000 years. Accelerated decay must have produced a billion years worth of helium in that short amount of time."<ref name="cwye" />

#:"Uranium and thorium generate helium atoms as they decay to lead. A study published in the ''Journal of Geophysical Research'' showed that such helium produced in zircon crystals in deep, hot Precambrian granitic rock has not had time to escape.25 Though the rocks contain ''1.5 billion years'' worth of nuclear decay products, newly-measured rates of helium loss from zircon show that the helium has been leaking for only '''6,000''' (± 2000) '''years'''.26 This is not only evidence for the youth of the earth, but also for episodes of greatly accelerated decay rates of long half-life nuclei within thousands of years ago, compressing radioisotope timescales enormously."<ref name="icrye" />

#:"The core of the sun produces deuterium from hydrogen fusion at 5 million degrees K. The heat is transferred from the core by convection currents so it could reach surface in days, not a million years. It also leads to an age for the sun based on the deuterium/hydrogen ratio of the local interstellar medium of 6,000-12,857 years."<ref name="cwye" />
