Radioactive decay half life calculator

The following tools can generate any radioactive decay half life calculator of the values from the other three in the half-life formula for a substance undergoing decay to decrease by half. Half-life is defined as the amount of time it takes a given quantity to decrease to half of its initial value. The term is most commonly used in relation to atoms undergoing radioactive decay, but can be used to describe other types of decay, whether exponential or not.

Post a Question. Our half-life calculator gives accurate answers to the calculations involving various parameters pertaining radioactive decay. It also displays the formula used in the computation and steps followed in arriving at the answer. You need to follow key steps when using this calculator. Here you click drop down arrow and select the parameter or the quantity you want the calculator to compute. Radioactive materials are generally unstable and therefore undergo spontaneous disintegration radioactive decay to form a stable nuclide, radiations and energy. The amount in this case refers to mass or number of atoms of a radioactive sample.

The half-life calculator is a tool that helps you understand the principles of radioactive decay. You can use it to not only learn how to calculate half-life, but also as a way of finding the initial and final quantity of a substance or its decay constant. This article will also present you with the half-life definition and the most common half-life formula. Each radioactive material contains stable and unstable nuclei. Stable nuclei don't change, but unstable nuclei undergo a type of radioactive decay , emitting alpha particles, beta particles, or gamma rays and eventually decaying into stable nuclei. Half-life is defined as the time required for half of the unstable nuclei to undergo their decay process. Each substance has a different half-life. For example, carbon has a half-life of only 19 seconds, making it impossible for this isotope to be encountered in nature. Uranium, on the other hand, has a half-life of about years. This term can also be used more generally to describe any kind of exponential decay - for example, the biological half-life of metabolites. Half-life is a probabilistic measure - it doesn't mean that exactly half of the substance will have decayed after the time of the half-life has elapsed. Nevertheless, it is an approximation that gets very accurate when a sufficient number of nuclei are present. Learn more about that by checking out our Radiocarbon dating calculator.

Imaginary Number Calculator. Percent ionic character The percent ionic character calculator allows you to find the behavior of a chemical bond between any two atoms.

Radioactive Decay Calculator is a free online tool that displays the half life of the given isotope. Step 3: Finally, the radioactive decay of the given isotope will be displayed in the new window. In Physics, the radioactive decay is defined as the spontaneous breakdown of the nucleus, which results in the release of energy and also the matter from the atomic nucleus. It is noted that the radio-isotopes do not have enough binding energy to hold the nucleus in the atom. It means that the radio-isotopes have unstable nuclei. During the radioactive decay, the atomic nucleus becomes unstable, and there occurs the imbalance in the proton and neutron number. Your Mobile number and Email id will not be published.

Use Radioactive Decay Calculator to obtain the exact radioactive decay or half-life of the isotope easily. All you have to do is enter the isotope name and initial activity, decay time and half-life details to get the final activity value.
