Learning objective

Understand that radioactive decay involves a transformation in an unstable nucleus, which may lead to the release of alpha (α), beta (β), or gamma (γ) radiation. Recognize that these transformations occur spontaneously and randomly.

Read the explanation, check the common trap, then practise with flashcards and questions.
