2. COVERED TODAY
RADIOACTIVE RADIATION IN DAILY
LIFE
SAFE AND PROPER HANDLING OF
RADIOACTIVE SUBSTANCE AND
RADIOACTIVE WASTE
APPRECIATING THE IMPORTANT OF
RADIOACTIVE RADIATION
What is a radioactive radiation?
Example of radioactive radiation :
Alpha radiation (α)
Beta radiation (β)
Gamma ray (γ)

3. FOR INSPIRATION
Isaac Asimov
Today's science fiction is
tomorrow's science fact.

4. ARCHEOLOGY AND
GEOCHRONOLOGY
CARBON -14 DATING METHOD
Carbon-14 dating is a way of determining the age of certain
archeological artifacts of a biological origin up to about 50,000 years
old. It is used in dating things such as bone, cloth, wood and plant
fibers that were created in the relatively recent past by organisms
activities. As soon as the organisms die, the amount of c-14 in their
tissue decline because they decay by emitting beta radiation with a
half-life. T1/2 of 5700 years.

5. MONITORING THE
THICKNESS OF
METAL SHEETS
(INDUSTRY)
IN FACTORY:
THE METAL SHEET PASSED IN BETWEEN
BETA RADIATION SOURCE AND
DETECTOR. IF THE BETA RADIATION
DETECTOR DETECTS TOO MUCH BETA
RADIATION, SO THE METAL SHEETS IS
TOO THIN.
AGRICULTURE
Radioactive radiation is used to kill
beetles, control the population of pests
by sterilisation, determine the best type
of phosphate fertiliser, modify the
characteristics of plant and determine
the absorption of phosphate in plants by
using the rate at which beta radiation is
emitted during the nuclie decay of
phosphorus-32 (p-32)

6. DEFENCE
NUCLEAR BOMB
RADIOACTIVE RADIATION RELEASED FROM THE
EXPLOSION OF NUCLEAR BOMB DESTROY ALL LIVING
THINGS IN THIER RADIUS INCLUDE HUMANS AND ITS
EFFECT EXISTS FOR GENERATIONS
DID YOU KNOW?
IN 20 SEPTEMBER 2017, MALAYSIA
IS SIGNED THE ICAN AGREEMENT
TO BAN NUCLEAR WEAPONS AT A
UNITED NATIONS (UN)
CONFERENCE
TODAY - The Most Powerful Nuclear
Bombs is RDS-220 Hydrogen Bomb
—"Tsar Bomba" (50 Megatons)

7. FOOD
PRESERVATION
The radura logo is used to label food
preserved using radioactive radiation
such as gamma rays. The role of
gamma rays is to kill bacteria in the
food.
MEDICAL
In medical, its used in some method
such as radiotherapy to kill cancer
cells and shrink tumors and x-ray to
produces image and detect health
problem inside your body.

8. RADIOACTIVE
SUBSTANCES
AND WASTE
SAFE AND PROPER HANDLING OF

9. SAFETY MEASURES WHEN HANDLING
RADIOACTIVE SOURCE AND WASTE
STORE IN THE THICK LEAD
WALLS CONTAINER.
DISPOSAL OF RADIOACTIVE WASTE DONE
SAFELY AND PROPERLY.
WEAR APPROPRIATE PROTECTIVE
CLOTHING WHE HANDLING RADIOACTIVE
SUBTANCES
ROBOTIC HANDS ARE USED TO HANDLE
RADIOACTIVE SUBTANCES SAFELY.
RADIOACTIVE SUBTANCES IS SHIELDED
WITH THICK SLABS OR LEAD
USE RADIATION BADGES TO DETECT THE
DOSE RATE OF RADIOACTIVE RADIATION
ABSORBED INTO THE BODY

10. - THE IMPORTANT OF RADIOACTIVE RADIATION FOR THE WELL-
BEING OF HUMANS
- MAKE US GREATFUL TO THE ALMIGHTY FOR CREATING
RADIOACTIVE PARTICLES THAT HAVE MANY USES TO SUSTAIN
LIFE
- MANY ARTIFICIAL RADIOACTIVE ELEMENTS HAVE BEEN
CREATED BUT WITHOUT RADIOACTIVE PARTICLES THEY
CANNOT BE PRODUCED
