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 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.

Radiation is quite dangerous, and in order to understand it and its risks, scientists introduced many measurement units: our radioactive decay calculator will teach you how the activity of a substance is measured. Here you will learn:. Sometimes, important discoveries happen by chance: this was particularly true at the end of the XIX century when decades of experiments with electricity and photography finally led to the initial understanding of the phenomenon of radioactivity. He discovered that shielding that radiation was not stopping another kind of ray: X-rays. The origin of X-rays was not known at the time, and the French physicist Henri Becquerel was investigating the possibility of using solar-stimulated uranium salts to emit X-rays. He did this by trying to impress a photographic film after the salts were exposed to the sun and wrapping them in black paper. Those were truly the Age of Exploration in physics.

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

Given the mg of a radioactive sample decayed to 50 mg in 20 minutes, what is the half-life of this nuclide? The applications of half-life calculation and exponential decay are many, as it has uses in electrostatics, chemical reaction rates, geophysics, archeology, fluid dynamics, heat transfer, optics, luminescence, pharmacology and toxicology, thermoelectricity, vibrations and, of course - radioactivity. You can post a question for a tutor or set up a tutoring session Post a Question. On the other end of the spectrum we have Uranium with a half-life of about years. Mean lifetime can be related to decay constant and half-life using the following formulae. This equation is used in the calculator when solving for half-life time. Uranium, on the other hand, has a half-life of about years. Alternatively, you can multiply ln 2 by the mean lifetime. 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. Try our exponent calculator. How to calculate the half-life Determine the initial amount of a substance. If you are not certain that our calculator returned the correct result, you can always check it using the half-life formula. Examples Half-life of a radioactive nuclide can be calculated using measurements on ch This means that after years have elapsed, half of an initial quantity of carbon would have disintegrated. It is incorporated into plants through photosynthesis, and then into animals when they consume plants.
