If radiation shields are effective, why haven't the manufacturers put one in their phones?

The main reason is that for years the cell phone manufacturers have told us radiation levels of phones were so low it was similar to a hairdryer but in the meantime they have been raising the power of their phones to give you better reception, thus increasing the cell phone radiation levels.

As well they have told you that shields do not work, yet recent news reports uncovered patents by the manufacturers indicating that they are planning on putting a shield inside their phones. We expect that the results of recent liability law suits against the cell phone makers may change the future manufacturing standards.
