**Radioactive Decay** **Definition:** Radioactive decay is the emission of energy in the form of ionizing radiation. **Types of Radioactive Emission:** - **Alpha emission:** \( \mathrm{H/2\,He} \) — Two protons and neutrons bound together are emitted from the nucleus. - **Beta emission:** \( 0 / -1\, B \) — Electron emission from the nucleus during some kind of radioactive decay. - **Positron emission:** \( 0 / +1\, B \) — A positron, which has the same mass as an electron but is positive, is emitted. - **Gamma emission:** \( 0 / \gamma \) — High-energy electromagnetic wave emitted from a nucleus transitioning from an excited state to a ground state. --- **Nuclear Radiation** Applications of nuclear radiation include: - Radioactive dating - Use of radioactive nuclides in medicine - Use of radioactive nuclides in agriculture **Negative effects:** - Contamination - Disposal issues **Definition:** Nuclear radiation is the energy released from the nucleus of an atom, often in the form of high-speed particles or electromagnetic waves. --- **The Ozone:** **Formula:** O₃ Ozone is formed and destroyed constantly in the stratosphere....
