20 Oct 2024 Tags: Nuclear Engineering Nuclear Chemistry Nuclear Chemistry Radiochemistry calculation Popularity: ⭐⭐⭐Radioactive Decay CalculatorThis calculator provides the calculation of the number of atoms remaining after radioactive decay.ExplanationCalculation Example: Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation. The number of atoms remaining after radioactive decay can be calculated using the formula N = N0 * e^(-lambda * t), where N0 is the initial number of atoms, lambda is the decay constant, and t is the time elapsed.Q: What is the half-life of a radioactive element?A: The half-life of a radioactive element is the amount of time it takes for half of the atoms in a sample to decay. It can be calculated using the formula t1/2 = ln(2) / lambda.Q: How can radioactive decay be used in real-world applications?A: Radioactive decay has many applications in the real world, such as carbon dating, medical imaging, and cancer treatment.Variables Symbol Name Unit t Time Elapsed s lambda Decay Constant 1/s N0 Initial Number of Atoms atoms Calculation ExpressionRadioactive Decay Function: The number of atoms remaining after time t is given by N = N0 * e^(-lambda * t).N0 * Math.exp(-lambda * t)CalculatorTime Elapsed (s): Decay Constant (1/s): Initial Number of Atoms (atoms): Calculated valuesConsidering these as variable values: lambda=5.0E-4, N0=1000.0, t=100.0, the calculated value(s) are given in table below Derived Variable Value Radioactive Decay Function 1000.0*math.0.0 Sensitivity Analysis GraphsRadioactive Decay Function: The number of atoms remaining after time t is given by N = N0 * e^(-lambda * t).Impact of null on Radioactive Decay Function TGvar = [0.001 TO -0.001] f(TGvar)=N0 * Math.exp(-TGvar * t) Impact of null on Radioactive Decay Function TGvar = [1000.000 TO -1000.000] f(TGvar)=TGvar * Math.exp(-lambda * t) Similar Calculators Nuclear Reaction Calculations Fundamentals of Nuclear Engineering Calculations Nuclear Reactivity Calculations Fundamentals of Nuclear Reactor Analysis Nuclear Reaction Calculation Nuclear Thermodynamics Formulas Principles of Nuclear Reactor Calculations Theoretical Nuclear Attribute Computation Nuclear Thermodynamics Fundamentals Nuclear Composition CalculationExplore Radioactive decay Nuclear physics Chemistry Calculate the specific activity of a 10mCi sample of Co-60 if it occupies a volume of 1000 liters.

Bimal Raut September 16, 2022 Nuclear chemistry Thorium (4n) SeriesUranium (4n+2) SeriesActinium (4n+3) SeriesNeptunium (4n+1) SeriesList of radioactive seriesRadioactive Series VideoReferencesThe radioactive series also called as radioactive decay series is the series of elements obtained by successive disintegration of a parent radioactive element to a non-radioactive stable element. The series of elements obtained from 90Th-232, 92U-235, and 92U-239 are natural radioactive series, while the series obtained from artificially prepared 93Np-237 is called radioactive series.When a radioactive element emits α or β particles, the new daughter elements are formed and may have unstable nuclei. The daughter element further disintegrates by emitting α and β particles forming new elements. The process of disintegration is continued until a non-radioactive stable element is obtained. Thus, the formation of the stable nucleus from a radioactive element is not a one-step process.There are four series of radioactive elements.Thorium (4n) SeriesUranium (4n+2) SeriesActinium (4n+3) SeriesNeptunium (4n+1) SeriesThorium (4n) SeriesIt begins with the radioactive elements, Uranium-232 and ends with stable non-radioactive lead (Pb)-208. The mass number of all elements are integral multiple of 4.Uranium (4n+2) SeriesThe parent element, uranium-238, is used as its starting parent radioactive elements which undergo disintegration and form lead-206 as its final stable component. Since the mass number of all elements in this series gives a remainder of 2 when divided by 4, it is called the (4n+2) series, where n is an integer. It possesses the longest half-life.Actinium (4n+3) SeriesThe radioactive element uranium-235 converts into Lead-207, a stable element as the final product. Since the mass number of all elements in this series gives a remainder of 3 when divided by 4, it is called the (4n+3) series, where n is an integer.Neptunium (4n+1) SeriesThe elements in this series are not found in nature. It begins with Bismuth-200 and terminates into stable neptunium-237. The mass number of all elements in this series gives a remainder of 1 when divided by 4, hence is called the (4n+1) series.List of radioactive seriesThe various radioactive series with their starting element, end-stable elements, and the half-life is presented below:SeriesName of SeriesStarting Radioactive ElementStable Non-Radioactive ElementHalf-life of Starting Element4nThorium90Th-23282Pb-2081.3 ×1010 year4n+1Neptunium94Pu-24183Bi-2094.5 ×109 year4n+2Uranium92U-23882Pb-2067.1 ×108 year4n+3Actinium92U-23982Pb-20713.2 yearRadioactive Series VideoReferencesAtkins, P.

A radioactive element, and the radioactive emissions (see How Nuclear Radiation Works) energize the phosphor continuously. In the past, the radioactive element was radium, which has a half-life of 1600 years. Today, most glowing watches use a radioactive isotope of hydrogen called tritium (which has a half-life of 12 years) or promethium, a man-made radioactive element with a half-life of around three years. Frequently Asked Questions Can glow-in-the-dark items be recharged indefinitely, or do they lose their glow over time? Glow-in-the-dark objects can be recharged repeatedly by exposure to ultraviolet (UV) light. Yet, their glow may weaken over time as the phosphor material degrades, particularly with frequent exposure to intense light sources or UV radiation. Are there any safety concerns associated with the materials used in glow-in-the-dark items? Most modern glow-in-the-dark items use safe, non-radioactive phosphors like zinc sulfide and strontium aluminate. However, items using radioactive elements for continuous glow, such as certain watches, are regulated to ensure they are safe for everyday use and exposure. Lots More Information
