Here, we present a radioactive decay calculator, which calculates the amount of radioactive activity a substance will have after decaying for a given time. The formula for radioactive decay is derived from the familiar exponential decay formula and is as follows:. Selecting an isotope from the drop-down will automatically populate the half-life field the provided half-life can be edited as desired.

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. In terms of activity, half-life can be defined as the time it takes for the activity disintegration per second of an unstable nuclide to decrease by one-half as it undergoes radioactive decay. Radioactive decay yields stable nuclides, particles alpha, beta, gamma rays and energy. Change in the mass of nuclide, number of atoms as well as the time it takes for the decay to occur are useful in the calculation of half-life. Radioactive nuclides have different unique half-lives that are independent of concentration and environmental factors such as change in temperature and pressure. The half-lives of these radioactive isotopes range from fractions of a second to billions of years. For example, Nobelium has a half-life of 3 seconds while uranium has a very long half-life of 4. Half-live has been used to describe other decays which may or not be exponential. In medical sciences for example, half-life describes the change in the concentration of a drug in the body.

It is incorporated into plants through photosynthesis, and then into animals when they consume plants.

The following tools can generate any one 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. One of the most well-known applications of half-life is carbon dating. The half-life of carbon is approximately 5, years, and it can be reliably used to measure dates up to around 50, years ago. The process of carbon dating was developed by William Libby, and is based on the fact that carbon is constantly being made in the atmosphere. It is incorporated into plants through photosynthesis, and then into animals when they consume plants.

This calculator will calculate the half-life, initial quantity, quantity remained, and time, with steps shown. There are units of mass of a substance with a half-life of units of time. In units of time, there will remain units of mass of the substance. The Half-Life Calculator is a tool designed to explain the concepts of radioactive decay. It is not only for mastering half-life calculations but also for determining the initial and remaining amounts of a substance or its half-life. Of the four values starting quantity, remaining quantity, half-life, time , enter any three. The fourth will be calculated.
