The science of radioactive decay explains how unstable atomic nuclei transform into stable ones through emission of radiation, following precise mathematical patterns and physical laws. This fundamental concept in nuclear physics is crucial for understanding radioactive dating and nuclear applications.
- Radioactive decay involves unstable nuclei transforming into stable ones through emission of alpha, beta, or gamma radiation
- The process follows a statistical probability law known as the "loi de décroissance radioactive"
- Half-life (t₁/2) is a key concept measuring the time taken for half of radioactive nuclei to decay
- The decay process is random and irreversible, following an exponential decrease pattern
- Three main types of radioactivity are identified: alpha (helium nuclei), beta (electrons/positrons), and gamma (electromagnetic radiation)
