An online database will now allow mobile phone users to see how much radiation they may be exposed to because of their cells.
According to a report carried out in www.news.com.au, the database, created by the Environmental Working Group in Washington, ranks more than 1000 mobiles by the amount of radiation they emit.
AdvertisementIn terms of handsets currently on the market, manufacturer Samsung came out on top with five phones in the list of 10 lowest emitters.
However it appears the specific handset model is more important than the brand when it comes to radiation.
Motorola's RAZR V8 was ranked second in the list of lowest emitters - but there were also five Motorola phones at the other end of the scale.
Similarly, the BlackBerry Storm 9530 was ranked 12th in the list of lowest emitters, but the BlackBerry Bold 9000 and two BlackBerry Curve models were among the highest.
The handsets were ranked on a measurement called the specific absorption rate, or SAR, that gauges how much energy a person absorbs while using or wearing a phone.
A handset's SAR is expressed in watts per kilogram (W/kg).
The highest-emitting phone on the market, the Motorola MOTO VU204, had a SAR value of 1.55 W/kg. The lowest, the Samsung Impression, had a value of between 0.15 and 0.35 W/kg.
The top SAR value allowed in Australia is 2 W/kg.
The Environmental Working Group said that it created the database after recent studies linked using mobile phones for more than a decade with health risks including brain tumours.
"Recent research has prompted serious concerns about exposure to wireless emissions," it said.
"We at Environmental Working Group are still using our cell phones, but we also believe that until scientists know much more about cell phone radiation, it's smart for consumers to buy phones with the lowest emissions," it added.
