The document discusses the hazardous effects of mobile phone usage on human health, highlighting issues such as cancer, genetic damage, and neurological problems due to electromagnetic radiation emitted by mobile devices. It outlines the working mechanism of mobile phones and the concept of Specific Absorption Rate (SAR), as well as precautionary measures to mitigate health risks. The conclusion emphasizes the need for public awareness about the health risks associated with mobile phone use, despite their prevalence in daily life.

2. INDEX
▪ Introduction.
▪ General Discussion.
▪ SAR(The Absorption Rate).
▪ Health Hazard.
▪ Disadvantages.
▪ Precautions.
▪ Conclusion.

3. INTRODUCTION
Mobile Phone:
• Also know as Cellular phone or cellphone
• Its is a portable telephone discovered at late
20th century.
▪ Allows to make calls and send messages,
among other features.
History And Evolution of Mobile Phone :
• From 1950 -1970s mobile phone large and heavy
to carry while travelling.
• Dr. Martin Copper is the first inventor of Mobile
Phone & in large scale by Motorola Company
1973.

4. GENERAL DISCUSSION
Working of Mobile phone tower:
▪ Mobile tower consists of antennas that is both
transmit and receive signals
▪ While making call on mobile phone ,it emits
electromagnetic radio waves, know as radio
frequency.
▪ Antenna from nearest cell tower, receive this
radio waves.
▪ After receiving signal , cell tower transmits
signals to a switching center-telephone
exchange for mobile phone.
▪ Here mobile phone is connected to either to
another mobile phone or telephone networks.

5. Mobile Phone Produce Radiation:
• Uses electromagnetic radiation in the
microwave range 450-3800MHz.
• Devices which emits electromagnetic radiation
have the dark side of technology that can
effect human health.
• Exposure to cell phone electromagnetic
radiation :
• Irradiates mainly to the side of head and to the
body parts closest to the phone.
• Produce both thermal and non thermal effects.

6. THE SPECIAL ABSORPTION RATE (SAR)
OF A CELL PHONE:
▪ Amount of radio frequency (R.F)
energy absorbed from the mobile
phone into users body .
▪ In INDIATelecom Communication
is handle by Government body
i,.eTelecom Regulatory Authority
of India(TRAI).
▪ Comparing SAR values between
phones can be misleading .

7. MOBILE PHONES HEALTH HAZARDS:
Cancer: mainly brain cancer.
Genetic damage.
Brain and other neurological problems.
 Birth defects.
Increased blood pressure.
Disturbed sleep.
Effects on sperm count in male.
Increases stress levels.
Increases risk of chronic pain: causing pain and inflammation of joints.
Increases risk of EyeVision Problem.

8. DISADVANTAGES:
 Negative effect on health.
 Mobile PhoneTowers.
 Increase Expenses.
Time Distraction.
 Use in classroom and Examination hall.
 Dangerous in driving.
 Home for micro-organism.

9. PRECAUTIONS:
 Use a headset or loud speaker mode i.e this
things help in keeping phone away from head.
 Use mobile phone for shorter conversations.
 Limit children from using mobile phone
reason: its effects to fast to children in various
ways nowadays.
 Avoid using cell phone in weak signal areas.
 Avoid using while driving on the road.
 Avoid keeping mobile phone front side of jeans
pant pocket :reduce risk of male fertility.
 Avoid keeping mobile phone switched on in
upper pocket.

10. CONCLUSION:
 Research shows that mobile
phone electromagnetic radiation
lead to cause cancer ,infertility
,eye -sight problems , destroy of
brain cells,.etc which are main
concern of health.
▪ By knowing the disadvantages of
mobile phone then also we tends
to use mobile phones day to day
life.
▪ Limiting the use of mobile phone
solely dependents on public.
▪ At last, can be tackle by making
awareness among public.
FIRST YOU TAKE THE STEP TOWARDS
AWARENESS
