Radioactive decay results in a reduction of summed rest mass, which is converted to energy (the disintegration energy) according to the formula E = mc2. This energy is released as kinetic energy of the emitted particles. The energy remains associated with a measure of mass of the decay syste...
Fig. 1. Alpha decay. An example of this decay occurs in the uranium-238 nucleus that decays into thorium-234 nucleus. Alpha particle has a relatively large mass, positive electric charge, and poor radiation penetration, and it can be stopped by a paper sheet (Ilem-Ozdemir and Asikoglu, 20...

An amended formula for the decay of radioactive material is presented. It is a modification of the standard exponential formula. The new formula applies for long cosmic times comparable to the Hubble time. It reduces to the standard formula for short times. It is shown that the material decay...
Half-Life formula You can find the half-life of a radioactive element using the formula: wheret1/2is the half-life of the particle,tis the elapsed time,N0is the quantity in the beginning, andNtis the quantity at timet. This equation is used in the calculator when solving for half-life...

The formula for radioactive decay over time is N = N0eλt . The formula for how many number of atoms counted by the Geiger as distance (x) changes is C = k/x2. How can I merge these formulas to give one that accounts for distance and time? Secondly, how does the second formula...
For example, the β+ decay process for mainly used positron-emitter fluorine-18 (18F) is written as (6.2)F918→O818+β+ In this decay process, the 18F atom as a parent radionuclide is converted into a daughter nucleus of 18O, and a positron will be ejected. Then, the phenomenon of ...
