The document discusses the history and evolution of mobile phones from early predecessors on ships and trains to Martin Cooper inventing the first mobile phone in 1973. It outlines both good effects like easy communication and emergency use as well as potential bad health effects from radiation. The document provides tips to reduce harmful radiation effects such as using a headset or speakerphone and keeping phones away from the body. Mobile phones can also negatively impact the environment when discarded due to toxic chemicals in landfills and disorienting birds when exposed to electromagnetic fields.

3. HISTORY AND EVOLUTION OF MOBILE
 A hand mobile radio telephone is an old dream of
radio engineering.
 Early predecessors of cellular phones included
analog radio communications from ships and
trains
 Martin Cooper is the first inventor of Mobile
Phone & in large scale manufactured by Motorola
Company in 1973.

4. GOOD EFFECTS OF USING MOBILE PHONE
 You can easily communicate with others

 We can use Internet Banking work.
 Now a days people use mobile phone not only for
talking but also use for internet, specially
chatting, searching for something or taking
pictures & shopping.
 We have seen that during recent pandemic
(Covid-19) all process of studies were possible
only through mobile phones.

5. BAD EFFECTS OF USING MOBILE PHONE

6. EFFECT ON NATURE
 Deterioration & damage: Mobile phones leak
dangerous chemicals and materials into their
surroundings when they are thrown out. Hence, if
we do not recycle mobile phones, these damaging
chemicals and materials may very well wind up in
our already overloaded landfills. Lead, mercury
and arsenic are among some of the toxic
chemicals. While your mobile only has a very tiny
amount of each of these chemicals , you need to
look at the big picture of over millions of them
being thrown out annually.
 Killing Birds : Researchers found that robins
were disoriented when exposed to a vertically
aligned, broadband or a single-frequency field.

7. TIPS FOR REDUCING POTENTIAL HARMFUL
EFFECTS OF MOBILE PHONE RADIATION
When on a call, use a wired headset or speakerphone mode.
Place the mobile phone away from your body when on a call.
Do not carry mobile phones in pockets of your close of Heart.
Avoid using a mobile phone when you are driving & when
getting trains, buses ,cars & road & rail line crossing.
Turn the mobile phone off when you don't need to use it.
Do not allow children under 18 to use a mobile phone except
in emergencies.

Mobile phone is not only useful to a person every
time but It is also a cause of danger
