In India, mobile phones overtook
fixed phones in 2005
India is the 2nd largest market in the worldfor mobile phones.

WHO Concern of Mobile Hazards
Because of Electro -Magnetic Radiations

Specific Absorption Rate
Specific Absorption Rate (SAR) is a measure of the rate at which energy is absorbed by the body when exposed to
a radio frequency (RF) electromagnetic field15
X-rays

RECOMMENDATIONS FOR SAFE USE OF MOBILES
55
1. Minimize the duration of use
Not more than 3
minutes
Atleast 15’
intervals56
2. Use hands-free to decrease the radiation to the head
57
Use speaker phone or headset
Step 3
58
Step 5
· Limit the use of cell phones by at-risk population (such as children).
4. Limit use of cell phones by children59
5. Avoid living near the base stations
60
Step 6
61
7. Never use a cell phone when a
conventional phone is available
62
Mobil8. Mobile phones prohibited near
ICU and OT
63
9. The practice of installing
antennas needs to be regulated
64
10. The SAR value for each hand set
should be provided by the manufacturers
65
HEALTH HAZARDS OF COMPUTER USE
Computer cannot kill?
66
All Are Avoidable
67
Eye Strain
Also called Computer
Vision Syndrome 68

Carpal Tunnel Syndrome
76
Ergonomic Keyboard
77
Use a mouse pad with wrist rest
78
Wrong Keyboard Position
Hands at angles -Nerves at the wrist
are trapped
Elbows away from body -Causes a static load -
Aching shoulders and neck79
Correct Keyboard Position
