Hi, I sent my Nexus s to Samsung to get it fixed about a week ago. Now, I see the repair status online, and it say "radiation test passed." Does anyone know how they test the "radiation" on the phone? And If the test is passed on my phone then I don't have to worry about radiation from the phone?
The fact that they replaced all the parts in my phone make me worry if the radiation is not safely removed...........


Somebody help me out please because I'm in the process of something in which I must avoid even a little amount of radiation.
