Radioactivity in real life

Radiation is typically measured using a Geiger Muller (GM) tube, which ticks for every radioactive particle it detects.

Radioactivity can be harmful to the human body but, if used in a controlled and careful manor, can provide helpful medical benefits.

Radioactivity has many applications in the real world and has played a role in many experiments throughout history since its discovery by Henri Beckquerel when he noticed Uranium salts leaving shadows on film.
