The EU including the UK signed up to the concept of the Precautionary Principle back in 2000.  

The subsequent 2011 IARC 2B classification for all RF (i.e. Microwaves etc.) exposure is stronger than is needed for precautionary action.  And that is just for cancer. 

The precautionary principle applies where scientific evidence is insufficient, inconclusive or uncertain and preliminary scientific evaluation indicates that there are reasonable grounds for concern that the potentially dangerous effects on the environment, human, animal or plant health may be inconsistent with the high level of protection chosen.
