3. What is
Radioactive
Decay?
 
“Radioactivity is a process by which the
nucleus of an unstable atom loses energy by
emitting radiation. In the year 1896, Henry
Becquerel discovered this phenomenon.”

4. Unit of
Radioactivity
S.I Unit is Becquerel.
It can be expressed in
different unit i.e.
Curie
1 Curie=3.7×10
10
dps
1 Curie=3.7×10
10
Bq
Radioactivity can
also expressed in
Rutherford

5. α
Beta decay is the
transformation of a
radionuclide by the
change of a proton into
a neutron, or vice versa,
and the emission from
the nucleus of an
electron or positron and
a neutrino
β
γ

6. Example of Alpha
Decay
92Ur238
90Th234+2He4 Example of Beta
Decay

α
β
γ

8. Uses of Radiation
It can be used to track the movement
of the Particular Substance though a
living organism.
It is used to determine the age of
ancient object.
Many uses in Medicine, from
imaging to cancer
Radioisotope
Labelling
Radiomatic
Dating
Other Uses

9. CONCLUSION
Radiation has always been present around us. Life has evolved in a world
containing significant levels of ionizing radiation. We are also exposed to
fabricated radiation from sources such as medical treatments and
activities involving radioactive materials. Since the early twentieth
century, radiation’s impacts have been considered in profundity, in both
the research facility and among human populaces. Because dangers of
radiation on the well-being are known, it must be carefully utilized and
entirely controlled.
