Half life age calculator
WebThis probability amounts to 50% for one half-life. In an interval twice as long (2 T) the nucleus survives only with a 25% probability (half of 50%), in an interval of three half-life periods (3 T) only with 12.5% (half of 25%), and so on. You can't, however, predict the time at which a given atomic nucleus will decay. WebOnce you have filled in all of the required fields in the Life Expectancy Calculator and clicked the calculate button, you will immediately receive an estimation of your Life Expectancy. You can also see the Life Expectancy of others your age, gender and race to compare results of the Life Expectancy Calculator.

WebNow, the equation λ = 0.693 t 1 / 2 can be used to find λ for 14 C. Solving for λ and substituting the known half-life gives 22.63 λ = 0.693 t 1 / 2 = 0.693 5,730 years = 1.21 × 10 −4 y −1. We enter that value into the previous equation to find t. 22.64 t = 0.0834 1.21 × 10 −4 = 690 years.
