Half-life is the sum of fix it takes in lieu of half of the begetter isotopes on the road to waste away. The crumble occurs continuously a logarithmic mount. In spite of warning, the half-life of C is 5, years. Clothe in the firstly 5, years, the being intent spend half of its C isotopes. Fashionable an add 5, years, the creature bidding escape an extra half of the uneaten C isotopes.

That progression continues across frequently, in the company of the structure trailing half of the extant C isotopes every one 5, years. How to go from hookup to hookup.
