SpletCarbon-14 is a radioactive isotope with a half-life of approximately 5,730 years. This means that after 5,730 years, half of the original carbon-14 has decayed into nitrogen-14. This makes it a relatively short-lived isotope and therefore not suitable for dating events that occurred millions of years ago, such as those in the Pliocene epoch. Splet13. avg. 2024 · The longest-lived isotope of lawrencium, 262 Lr, has a half-life of 3.6 h, while the shortest-lived isotope of lawrencium, 252 Lr, has a half-life of 0.36 s. As of this …

SpletThe time needed for the radioactive isotope to decay to 14% can be found using the formula: N(t) = N₀(1/2) (t/h) where N₀ is the initial amount of radioactive isotope, h is the half-life, and N(t) is the amount of radioactive isotope remaining after time t. We want to solve for t when N(t) is 14% of N₀. Therefore, we can write: Spletradioactive isotope toapatient results ina lower dose ofaradiation delivered, fora given activity administered, than if a longer-lived isotope ofthe same element hadbeen used.
