I mostly disagree.

The average reader here is smart enough to read that headline, notice that part of it is quoted, and infer that the article states that some health authority has recently said that cell phone signals are about as dangerous as lead, etc.

The average reader is also more than smart enough to discern that the article is not, in fact, stating that cell phone radiation is the exact same thing as, say, lead. It's a bit ludicrous to even think that folks would assume this.

That said, I also prefer original headlines, as a rule.
