I heard the report on Radio 2 news and I had to ask myself two questions: -
The reports that say electromagnetic fields may cause problems for pregnant women relate to very high levels typical of living close to transmission lines which are AC magnetic fields. I would expect an AC field to have a greater effect on stimulating cell activity than a DC field which the Volvo exhibits.
To get a high level of magnetic field in the Volvos mentioned, a high current must be flowing too / from the battery. This can only occur when starting the vehicle (50 - 200A) and also for a short period of time while the battery is charging (10 - 40A). Thereafter, the battery charge current would be very small (<1 amp)when the alternator provides the cars electrics and virtually no electromagnetic effect would be detectable.
It seems to me that the media have failed to give the public all the facts as usual.
I have concerns about long term use of mobile phones and exposure to electromagnetic radiation but do not see driving one of the above Volvos as a risk.
As the website suggests, there are few materials that can suppress electromagnetic fields. Mumetal is however an effective barrier with the bizzarre characteristic of losing its properties when flexed.
