Period 10 Activity Solutions: Nuclear Reactions
... Both stable Carbon-12 and unstable Carbon-14 isotopes are present in the atmosphere (in carbon dioxide). Living organisms absorb both isotopes of carbon in the process of respiration. After an organism dies, it no longer absorbs any new Carbon-14, and the Carbon-14 within it decays. We can accuratel ...

... The C-14 is oxidized to CO2, which circulates through the biosphere. When a plant dies, the C-14 is not replenished. But the C-14 continues to decay with t1/2 = 5730 years. Activity of a sample can be used to date the sample. ...

Particle Production In The Early Universe
... As an example of how pair production affected the composition of the early universe, consider the production of electrons and positrons as the universe expanded and cooled. At high temperatures—above about 1010 K—most photons had enough energy to form an electron or a positron, and pair production w ...

Background radiation
Background radiation is the ubiquitous ionizing radiation that people on the planet Earth are exposed to, including natural and artificial sources.Both natural and artificial background radiation varies depending on location and altitude.
