Using the archeological complete the age of a preserved plant fibers. So when we read the slope on a semilog plot, we need to remember to always take the logarithm of whatever values we read off the vertical axis. The slope of the line on the semilog plot corresponds to the same decay constant k, that we can identify in a normal exponential decay plot.

Finding the slope of straight lines, however, is generally much easier. By plotting data on semi-log plots, the scientist can better compare and identify different isotopes. Further information about an unknown radioactive isotope can be identified simply by analyzing the radiation that it shoots out of the isotope.

**Learning About Line Graphs**

Gamma radiation produces photons, beta decay produces electrons or positrons, and alpha decay releases entire alpha particles helium nuclei. What is a half-life? Half-life is defined as the amount of time it takes for half of an isotope to change into another isotope.

## Decay graphs and half lives article

Like the decay constant, the half-life tells us everything we need to know to guess what kind of isotope we might have. It even turns out that the two numbers are equivalent if you correctly solve the radioactive decay equation. This means that, like the decay constant, the half-life gives an estimate of the stability of a particular radioactive substance, and it can thus be used to identify unknown isotopes.
