Ways to Minimise RF Exposure
While there is no established scientific evidence that the use of smartphones causes any health effects and further research is being carried out, members of public can adopt the following measures to minimise your RF exposure:
- Use hands-free kit or speaker mode when talking on your mobile phones to keep the mobile phones further away from the head and the body
- Reduce your usage of your mobile phones and cordless phones
- Reduce exposure in children by encouraging moderate mobile phone use
- Refrain from using your mobile phones in areas with poor cell connectivity
- Reduce exposure by selecting mobile phones with a low Specific Absorption Rate (SAR) value
- Use wired connections (via LAN) instead of Wi-Fi
There are mobile phone accessories (e.g. shields) in the market which claim to reduce the exposure of RF radiation.
Based on the US Federal Trade Commission (FTC)6 and ARPANSA7, there is no scientific evidence that such accessories are effective in reducing the level of RF radiation emitted from the mobile phones. Furthermore, the so-called shields may interfere with phone signal, causing it to draw even more power to communicate with the base station, and hence, possibly emit even more RF radiation.
