Radioactive decay half life calculator

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.

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.

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. We can determine the number of unstable nuclei remaining after time t t t using this equation:. It is also possible to determine the remaining quantity of a substance using a few other parameters:.

During the radioactive decay, the atomic nucleus becomes unstable, and there radioactive decay half life calculator the imbalance in the proton and neutron number. Our versatile radioactive decay calculator supports many different time units and automatically converts them if the time unit you measure the time elapsed is different than the time unit you enter the half-time, decay constant or mean lifetime in.

Following the somewhat serendipitous discovery of radioactivity by Becquerel, many prominent scientists began to investigate this new, intriguing phenomenon. During the beginning of the twentieth century, many radioactive substances were discovered, the properties of radiation were investigated and quantified, and a solid understanding of radiation and nuclear decay was developed. The spontaneous change of an unstable nuclide into another is radioactive decay. The unstable nuclide is called the parent nuclide ; the nuclide that results from the decay is known as the daughter nuclide. The daughter nuclide may be stable, or it may decay itself. The radiation produced during radioactive decay is such that the daughter nuclide lies closer to the band of stability than the parent nuclide, so the location of a nuclide relative to the band of stability can serve as a guide to the kind of decay it will undergo Figure Although the radioactive decay of a nucleus is too small to see with the naked eye, we can indirectly view radioactive decay in an environment called a cloud chamber.

Reviewed by Steven Wooding and Jack Bowater. What is the half life of uranium? Total time. Post a Question. 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. We can determine the number of unstable nuclei remaining after time t t t using this equation:. How to calculate half-life using the calculator There are two scenarios the calculator can calculate the half-life, the first scenario is the when you have N t , N o and t as in the example above. Adding Complex Numbers Calculator. Decay constant can also be expressed in terms of N o and N t using the exponential decay equation;.

Maths Calculators. Each Nucleus Physics tutorial includes detailed Nucleus Physics formula and example of how to calculate and resolve specific Nucleus Physics questions and problems. Since it is a stochastic random process, the decay rate of a particular atom cannot be predicted, but it can be for a group of atoms of the same element and this is the basis of radiometric dating. Half-life is defined as the amount of time it takes a given quantity to decrease to half of its initial value. Contact Us. Supported time units include:.

Each radioactive material contains stable and unstable nuclei. This term should not be confused with mean lifetime , which is the average time a nucleus remains intact. On the other end of the spectrum we have Uranium with a half-life of about years. Step 3: Finally, the radioactive decay of the given isotope will be displayed in the new window. Bike Calculator. Nevertheless, it is an approximation that gets very accurate when a sufficient number of nuclei are present. On the other hand, one of the most common radium isotopes is radium, with a half-life of years!
