An explanation of this unique ceramic, including why it is of such great interest to scientists. Researchers use lanthanum aluminate to grow thin films of superconducting materials (including buckyballs) and hope it can one day be used...

This entry provides a summary of radioactivity in nature and the decay chain.

Learn about the units for measuring the amount of radioactivity and the categories of radiation dose.

Scientists discover and probe x-rays and radioactivity, while inventors compete to build the first radio.

A brief explanation of the process of gamma decay is provided.

Entry explores the process of beta decay which occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other.
