The SAR acceptable level is not as simple as it may seem since it depends upon the testing regime, but the recommendation by the European professional body is for it to be below 2W/kg for head and neck but for a 10g tissue mass.  Different territories have different SAR limits based upon their own legislative and guidance frameworks.

The SAR limit is set at a level that places it well below the level at which harm will occur and hence a small increase in exposure above the SAR limit is unlikely to be of any health consequence.  However, limits are there to ensure that controls are in place to prevent ‘creep’ toward the onset of effects so it is reasonable to adhere strictly to those limits.  The limits have been well published and understood for some time.

It should be possible for a patch or update to be downloaded in order to prevent the exposure from the phone rising above the limiting value. It is not clear why this particular phone appears to have a high SAR but it may be associated with the initial stage of connection when the phone is ‘looking’ for a transmit/receive signal.

Although considerable research on the matter continues, at the exposures associated with mobile phone usage, there have been no conclusive findings to suggest that health detriment arises from the use of mobile phones other than that arising from electrical heating and possibly effects that arise from long periods of use that alter sleep patterns.
