PHYIC CALCULATOR
Alpha Decay Energy Calculator
A precise tool.
What is the Alpha Decay Energy Calculator & How does it work?
Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle, consisting of two protons and two neutrons. This process reduces the mass number by four and the atomic number by two.
The energy released during alpha decay can be calculated using Einstein’s famous equation:
E = Delta m cdot c^2
E = Energy released, Delta m = Mass difference between parent and daughter nucleus plus alpha particle, c = Speed of light
The mass difference ((Delta m)) is typically given in atomic mass units (u), where 1 u (approx) 931.5 MeV/cΒ².

Frequently Asked Questions
What is alpha decay?
Alpha decay is a type of radioactive decay where an atomic nucleus emits an alpha particle, reducing the mass number by four and the atomic number by two.
How do I calculate the energy released in alpha decay?
Use Einstein’s equation E = Ξm Β· cΒ², where Ξm is the mass difference between the parent nucleus, daughter nucleus, and alpha particle, and c is the speed of light.
What does Ξm represent in the alpha decay energy calculation?
Ξm represents the mass difference between the parent nucleus, the daughter nucleus formed after alpha decay, and the emitted alpha particle.
Why is the speed of light used in the alpha decay energy calculation?
The speed of light (c) is used because it relates the mass difference to energy through Einstein’s famous equation E = mcΒ².
Can this calculator be used for any type of radioactive decay?
No, this calculator specifically calculates energy released in alpha decay. Other types of radioactive decay require different calculations.
What units should I use for mass and speed of light in the calculation?
Use atomic mass units (u) for mass and meters per second (m/s) for the speed of light, which is approximately 299,792,458 m/s.
How accurate are these calculations?
The accuracy depends on the precision of the masses used. Experimental data and nuclear physics tables provide the most reliable values for mass differences.
