9. NATURALLY – AS IN
226, CARBON –12
ARTIFICIALLY – ALTERING
ATOMS BY USING A NUCLEAR
REACTOR OR A CYCLOTRON.

10. • RADIOACTIVITY IS THE PROCESS WHEREBY
UNSTABLE ATOMIC NUCLIE RELEASE ENERGETIC
SUBATOMIC PARTICLES.
• FIRST DISCOVERED IN 1896 BY THE FRENCH
SCIENTIST HENRI BECQUEREL AFTER WHOM THE SI
UNIT FOR RADIATION, THE BECQUEREL, IS NAMED

11. EMITS

12. • RADIOACTIVE ISOTPES ARE UNSTABLE SO THEY
UNDERGO RADIOACTIVE DECAY EMITTING
RADIATIONS
• TILL THEY BECOME STABLE
• 3 TYPES OF RADIATIONS

25. • THE RADIOACTIVE ISOTOPES PLAY A CRUCIAL ROLE IN
VARIOUS FIELDS SUCH AS MEDICINE, INDUSTRY, AND
SCIENTIFIC RESEARCH.
• THEIR UNIQUE PROPERTIES ALLOW US TO DIAGNOSE AND
TREAT DISEASES, TRACE CHEMICAL REACTIONS, AND STUDY
THE AGE OF ANCIENT MATERIALS.
• HOWEVER, IT'S CRUCIAL TO HANDLE RADIOACTIVE
ISOTOPES SAFELY AND RESPONSIBLY TO MINIMIZE THEIR
POTENTIAL HARM TO THE ENVIRONMENT AND HUMAN
HEALTH. THE USE OF RADIOACTIVE ISOTOPES CONTINUES TO
ADVANCE AND BRING NEW BENEFITS TO SOCIETY, BUT IT'S
IMPORTANT TO STAY VIGILANT IN MANAGING THEIR RISKS
