Half – life or formerly known as Half – life period is one of the most common terminologies which is used in physics to define the radioactive decay of a specific sample or element over a specific period of time. We know radioactivity is a spontaneous phenomenon. It obeys the exponential...
The half-life of the extinct radiolanthanide $$^{146}\text{Sm}$$ , important for both geochronological and astrophysical applications, was re-determined by a combination of mass spectrometry and $$\alpha$$ -decay counting. Earlier studies provided only l
From the equation below, we can see that the longer the half-life of an isotope, the longer the mean lifetime will be. τ =t½/ln(2) How to Calculate Time Elapsed Using Radioactive Decay Using a technique known ascarbon dating, it’s possible to estimate the age of an organic comp...
