lives. [DOC] [TLE] radioactivity - How does a half-life work? - Physics Stack Exchange [PAR] Mar 6, 2014 ... Logically, shouldn't it take 2,865 years for the quarter to decay, rather than 5,730? 
... years, each single carbon-14 atom has a 50% chance of decaying. ..... get is a 
term called half-life, which means that after this time has elapsed, ..... Why is 
radioactive decay dependent on amount of substance available? [DOC] [TLE] Half-life - Wikipedia [PAR] Half-life (abbreviated t12) is the time required for a quantity to reduce to half its 
initial value. The term is commonly used in nuclear physics to describe how 
quickly unstable atoms undergo, or how long stable atoms survive, radioactive 
decay. ... N0 is the initial quantity of the substance that will decay (this quantity 
may be... [DOC] [TLE] Radioactive decay - Wikipedia [PAR] Radioactive decay is the process by which the nucleus of an unstable atom loses 
energy by ... This decay, called spontaneous fission, happens when a large

This is the time it takes for 50% of the original carbon-14 atoms to decay to 
nitrogen. [DOC] [TLE] Chapter 3 - Radioactive Decay Kinetics - Oregon State University [PAR] The unstable nuclei in a radioactive sample do not all decay simultaneously. 
Instead ... units of rate are (disintegration of nuclei/time) making the units of the
