Blackberry Z10 Radiation Levels (SAR)


There has been a lot of hype about the brand new Blackberry Z10. Some say it is a "game-changer" for the company, that has now renamed itself "Blackberry" and gotten ride of the old "RIM" moniker. The new phone is equipped with the latest operating system BlackBerry 10, and a few more interesting specs:

  • 4G/LTE connectivity
  • 8 mpx camera with 1080p HD video recording
  • LCD Touch Panel 4.2 inch 1280x768 (356pp)
  • Blackberry Blackberry HUB 10 with BBM Video etc. ..

As always, we at tawkon want to take a look beyond the regular review points and focus on what our users are most concerned about: radiation.


tawkon is a free application that will alert you when radiation from your phone spikes and suggest ways on how to minimize your exposure.

All Phones in the United States and Europe must be qualified/certified by a regulatory body before being sold in the market. In the United States this body is the FCC and their maximum SAR value allowed is 1.6 W / kg. However, these calculations are seen to be outdated by many experts and are made on the assumption that a person uses their phone once a week. 

We have done several studies on the SAR values of various new phones, and with the release on the new Z10, we decided we should include it in our list. The old Blackberry bold 9700 had an SAR value that was down right scary, coming quite close to the absolute limit set by the FCC, so we wanted to see if the Z10 faired any better:

Position Device SAR (in W/Kg)
1 Samsung Galaxy Note II 0.171 W/Kg
2 Samsung Galaxy Note 0.209 W/Kg
3 Samsung Galaxy S2 0.247 W/Kg
4 Samsung Galaxy Nexus 0.303 W/Kg
5 Samsung Galaxy S3 0.342 W/Kg
6 Google/LG Nexus 4 0.550 W/Kg
7 HTC One S 0.687 W/Kg
8 Samsung Galaxy Ace 0.840 W/Kg
9 Blackberry Z10 1.070 W/Kg
      10         iPhone 5         1.180 W/Kg
* Blackberry Bold 9700 1.370 W/Kg


We see that the Blackberry Z10 has made some progress on lowering it's maximum radiation output, but with value of maximum specific absorption rate of 1.070 W/Kg, Blackberry is still on the higher end compared to nearly all popular phones on the market.

While the new phone makes some progress compared to previous models, the BlackBerry Z10 is still lagging behind compared to Samsung Galaxy Note 2, Samsung Galaxy S3 values ​​as maximum exposure to electromagnetic waves. Out of the top ten "hot" phones, we found the Z10 to have the highest SAR value.

If you are concnered about radiation from your mobile phone, now Tawkon's got you covered with this hip new, limited edition retro handset. This new accesory works with all popular smartphone models, including the Blackerry Z10. It blocks 99% of radiation and looks cool, all at the same time!
