MobileBasic Facts – Basic Facts
Mobile Phones –
                Phones
• Allow communication from any location via a network of base stations
• Information is transmitted from the mobile phone to the base station and vice
  versa via high-frequency electromagnetic fields
• Radiation intensity is greatest close to its source, i.e. a mobile phone's antenna
• Radiation is only strong while the phone is transmitting, not while idle state
• Radiation decreases sharply with distance to the phone
• Radiation exposure during a call depends on:
  – mobile phone emits less when connection quality is good
  – better outdoors than in a building
  – improves with proximity to a base station
  – When connecting to the network and switching from one cell to another, mobile
    phones briefly transmit at maximum output power and this is only slowly
    reduced

SAR
        Exposure measurements

• SAR - Specific Absorption Rate
• Electromagnetic radiation (W) that is absorbed by the human body (kg)
• Determined using a human head "phantom"
• Published on the internet and in the instruction manuals
• SAR is measured in a "worst-case" scenario
• 1.6 W/kg exposure limit according to the International
  Commission on Non-Ionizing Radiation Protection
  (ICNIRP, adopted 1996)
• The lower SAR of the device, the lower the radiation that is absorbed by the
  body

Research


• Around 35 studies till today (starting 1996), all on adults


Interphone
• Published June 2010 - 13 countries, 10 years
• overseen by the World Health Organization (WHO )
• compared cell phone usage for more than 5,000 people with brain tumors
  (glioma and meningioma) and a similar number of healthy controls.
•    People who use their mobile phones for at least 30 minutes a day for 10
    years (“heavy users”) have a greater risk of developing brain cancer
    (30%- 40%).

Research Cont.


Cosmos
• World Health Organization (WHO) and the UK Health Protection Agency (HPA).
• Long term health monitoring of a large group of people to determine if there are any health
  issues linked to long term exposure to radio frequency energy from cell phone use.
• Started in 2010, COSMOS study will follow approximately 300,000 adult cell phone users in
  Europe for 20 to 30 years




Mobi-Kids
• International multi-center study involving 14 European and non-European countries
• Investigating the relationship between exposure to radio frequency energy from communication
  technologies including cell phones and brain cancer in young people
• Started in 2010, nearly 2000 young people between 10 to 24 years
