One problem seems to be that indeed three *separate* discipline groups are working, but often the group lacks essential background. So we see reports which do not include essential data, such as field strengths, or create confusion, such as that between SI and CGS units already discussed in this thread. We need cross-discipline teams that take time to understand each others' languages. >He concluded that more studies needed to be done, True, but every scientist concludes that - it's how they get paid. > but basically the health risk is at such a low level that it is >difficult to evaluate.

Reliable research some years ago showed that the cable to an earbud could transfer significant RF energy to the ear. Perhaps that no longer applies. -- OOO - Own Opinions Only.
