Background radiation comes from radioactive elements found naturally in the environment, such as rocks and food. Radiation is emitted from unstable atomic nuclei through random processes and can take the form of electromagnetic waves or energetic particles. The document instructs students to calculate their annual dose of background radiation using a Geiger-Muller tube and counter.
