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. 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 Your Mobile number and Email id will not be published.

Units for each entry are typed directly into the calculator text fields as shown by the example text. 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.

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.

Radioactive decay half life calculator

Use this decay calculator to easily calculate the time elapsed since the beginning of the decay, or calculate the original quantity, half-life a. Convert half-life to mean lifetime or decay constant, and vice versa by entering any of the three values in its respective field. 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. Supported units are nanoseconds, milliseconds, seconds, minutes, hours, days, weeks, months, and years.

What is half life of radioactive isotope? Bike Calculator. 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. Months are approximated to Section Modern Physics. Half-life is defined as the time taken by a substance to lose half of its quantity. Vapor Pressure Calculator. This term can also be used more generally to describe any kind of exponential decay - for example, the biological half-life of metabolites. The relation between half-life, mean lifetime and the decay constant can be expressed by the equation:. It is also possible to determine the remaining quantity of a substance using a few other parameters:. While random at the individual level, radioactive decay is predictable over a group of particles with some uncertainty. Adding Complex Numbers Calculator. Each substance has a different half-life.

Use Radioactive Decay Calculator to obtain the exact radioactive decay or half-life of the isotope easily.

It is incorporated into plants through photosynthesis, and then into animals when they consume plants. Alternatively, you can multiply ln 2 by the mean lifetime. This allows you to learn about Nucleus Physics and test your knowledge of Physics by answering the test questions on Nucleus Physics. 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.
