Exradia has launched a range of replacement batteries for popular models of mobile phones which incorporate its special magic circuit to interfere with the bad RF coming from your handset, but iPhone users, with their non-replaceable battery, will just have to suffer.

According to the release Exradia are "...surprised Apple has chosen to ignore this potential health issue", though the company admits there's no evidence that mobile phones cause problems that's no reason not to make a buck preventing those very problems.

It added, "...there is currently no scientific evidence that clearly demonstrates mobile devices are safe", says David Schick, chief executive, ignoring the fact that it's impossible to prove a negative.

No study can ever demonstrate that mobile phones don't damage human cells, or make peoples' heads explode, or cause their legs to drop off, we can only assert that in the majority of cases these things don't happen and play the odds the way we do every day watching TV, having a shower or using a computer: none of which has ever been demonstrated to be safe.

Last time we talked about Extradia we suggested that companies might be interested in the technology in order to demonstrate they had made an effort, but as the Extradia circuit interferes with low frequencies, while handsets churn out masses of high-frequencies, it seems unlikely any judge is going to accept such reasoning should a case come to trial.

But if you think your mobile phone is melting your DNA, and you think it's the low frequencies doing it, then you are welcome to spend 25 quid on a replacement battery from Exradia, unless you've got an iPhone - obviously. ®
