Nuclear tests, nuclear reactors and the use of nuclear weapons have also changed the composition of radioisotopes in the air over the last few decades. This lesson is the third in a three-part series about the nucleus, isotopes, and radioactive decay. Written below is the case as it appears on The Case of the Melting Ice student sheet. Describes radioactive decay to.

Scientific technology

The amount of cosmic rays penetrating the earth's atmosphere is itself affected by things like the earth's magnetic field which deflects cosmic rays. The carbon atoms are always decaying, but they are being replaced by new carbon atoms at a constant rate. Some of the first radiocarbon dates produced showed that the Scottish tombs were thousands of years older than those in Greece. Nitrogen normally occurs in a seven proton, seven nuetron, nitrogen state.
