Usually phones sold in the EU (Meizu is sold here, so…) have to comply with the EU norms and laws. Even if your value is right, it is nothing you need to be worried about, because that level of radiation is very low.
The EU allows a max. value of 2.
However, this means that if you put your phone next to your head, e.g. calling someone.
Thats why it is unhealthy to charge you phone under your pillow (radiation is lower then anyway ~ 0,5 SAR maybe). So always put it somewhere else.
