Where is your phone? A survey of phone location and perceived risk:
A pilot study
Mary Redmayne Centre for Population Health Research on Electromagnetic Energy (PRESEE),
Monash University, Melbourne, Australia
Background
Mobile phones emit electromagnetic radiation
All mobile phones emit a regular ‘handshake’ transmission
Apps make frequent transmissions while phone is in stand-by
This raises the question of possible health effects related to carrying a phone in stand-by against the body
Manufacturers advise against carrying or using against the body

Aims and purposes
1. To describe where cell phones are carried by adolescents and young women (age 12-40) when being used for a variety of purposes.
2. To enable power calculation for future women’s health studies.
3. To ascertain perception of health risks associated with cell phones and other transmitting devices

Methods
The survey is by questionnaire and answered online using Survey Monkey®.
Time 10-15 minutes depending on responses
Female adolescents and young women aged 12 to 40 are eligible to participate
Aim for broad socio-economic backgrounds and walks of life
Study being undertaken in Australia and Germany (P. Wiedemann, Karlsruhe Institute of Technology (KIT), Berlin, Germany)
Just Australian interim results presented here
A wide variety of places were approached and asked to notify their students/employees/members about the survey
Posters and notices for emailing were provided

Interim results (data collection not finished)
At the time of this preliminary analysis, there were 183 participants
Age range 13-40

For how long have you carried a mobile phone for with you at least half the time?

In what mode and how far from your head is your phone at night?
10% have the phone turned off at night
More than 80% keep the phone in stand-by overnight. Of these:
13% (of N=166) have the phone in stand-by and within 20 cms of their head
57% (of N=166) have the phone in stand-by and between 20 and 50 cms of their head

Stand-by? Flight mode?Turned off?
Why does this matter?
Because smartphones frequently transmit while in stand-by
Perceived health risks
We asked about a wide range of health conditions from headaches to cancer
