Yes, it would be a good step although I cannot tell you honestly how much we should lower this level. There is always the fact that people using regular cellphones, like you and me who buy them from a shop, assume that they're buying a safe phone off the shelf because the government is watching this. If after 10 years of using this cellphone I'm increasing my risk of getting brain cancer, something is wrong there. The safety standards are not protecting me.
