In physics

234 is the atomic mass number of the rare, but naturally occurring, radio-isotope uranium-234. It has a half-life of 246,000 years, the third-longest of a uranium isotope following U-238 and U-235. In nature, U-234 is the product of the decay of U-238. U-238 decays by the emission of an alpha particle, becoming the short-lived isotope thorium-234. This quickly decays by successive emission of two beta particles to become U-234.
