EMF Ratings for Cars
"Americans aren't aware of the dangers of electromagnetic radiation. We're endangering ourselves from TVs, cellular phones, neon lights, electric light bulbs...It didn't have to be this way."
Tom and Ray Magliozzi, NPR Car talk 9/13/14

Pregnant women exposed to 2.5 milli gauss for just 14 minutes per day have a 271% increased risk of misscarriages.

We're constantly being bombarded by electromagnetic fields (EMF). Driving is no exception. Not only are we radiated by cell towers strewn along highways, and exposed to high magnetic fields along the roads by an overtaxed power grid, but our very beloved cars are one of the more problematic sources of EMF.

The low frequency magnetic field impinged on the driver (passenger) of various makes and models is provided *.

The intensity of the magnetic field provides an indication of how offensive a car may be, but is not the sole measurement one should take. Other measurements include the RF as taken with an AM radio, and microwaves (the Trifield in RF mode). Magnetic fields are measured with a gauss meter. One can obtain the Trifield TF2 at various on-line stores such as LessEMF. The Trifield is under the category of "Combination Meters" because it measures magnetic, electric and Radio Frequency (RF) fields.

The first priority is to get a car with a low magnetic field. However, the measured magnetic field doesn't tell the whole story and should not be the sole criteria used in investigating a car.

For instance the magnetic field in the cabin of the Silverado is probably lowest of any modern vehicle. That is a good start, but the vehicle still causes tinnitus, and other ill symptoms. AM radio interference indicates pelting of EMF from the ignition system. Pulsed noise from the ignition is not detected by either gauss or RF meters. There is also a computer just under the steering column (directly in front of the driver) which was also detected by an AM radio. Additionally, the main fuse panel is on the driver's side, the battery is on the driver's side, the digital instrument cluster produces RF, and there's a very high magnetic field throughout the entire engine compartment.

Therefore, in the case of the Silverado the relatively low magnetic field at the vicinity of the driver can be deceiving. As we have seen with the Low Emission Computer ambient measurements can be negligible yet the computer can still cause devastating symptoms. Even if one doesn't initially feel any symptoms, in time one can become sensitized by the various low intensity frequencies of EMF. It is therefore imperative to drive a vehicle on a long trip before committing to buy it. Though the short ignition wires tame the effects of the ignition, direct ignition is preferred. Conventional AC Delco spark plugs have double the resistance (about 8K Ohm) of the titanium plugs and significantly reduce RF measurements.

One of the lowest rated cars listed is the 2005 Cadillac SRX (6 cylinder). Note: It's only the driver's seat that has the low magnetic field. The Passenger seat and rear of the car have elevated magnetic fields and are not as tolerable. The revamped 2010 SRX model is a magnetic hazard, so the low EMF SRX's are from 2005-2009. A few fundamental aspects of its design are beneficial for the driver, including:

- the battery is on the Passenger side of the car.

- the magnetic field under the hood (engine compartment) is relatively low on the drivers side.

- there are no computers near the driver.

- the direct ignition of the six cylinder engine emits relatively mild EMF, and there are no ignition wires. A setback is the fuse panel under the rear seat, and of course the instrument cluster.

Modern vehicles are laden with electronic gadgets, which leads us to consider older vehicles. For instance the 1967 Camaro has a very low magnetic field in the interior. The biggest concern, which should not be taken lightly, is the 8 cylinder ignition which has a distributor behind the engine block, near the center of the firewall. The ignition wires are also very long compared to modern cars which place individual coils packs close to the cylinders, reducing the length of the wires (as with the Silverado).

This particular vehicle has been retrofitted with a modern, electronic, High Energy Ignition (HEI) which has a hotter spark (40,000 volts) than the original points system (18,000 volts) and may explain why this car causes some chest pains. But the original resistive ignition 12 volt power wire is installed and inherent inductance in the long length of the wire minimizes the spark. Re-wiring the ignition power wire directly to the battery (and thus avoiding the circuitous rout to the ignition key) significantly reduces the magnetic field at the floor.

The metal dash must have beneficial shielding attributes. There are no computers aboard, no electronic instruments, no electric fuel pump, no electronic fuel injection, and the interior dash lights are dimmed with a rheostat rather than an electronic switching mechanism. GM really blew it with the 2011 Camaro coming in at a whopping 50 milli gauss (100 for Passenger)! The highest rating of any tested vehicle.

Probably the lowest EMF car one can get is a 1985 or older diesel Mercedes. That is if you and your neighbors can tolerate the exhaust fumes. It probably doesn't have air recirculation which is absolutely essential on today's stinking roads.

Besides the 2011 Camaro and some BMWs, one of the worst cars is a Saab. How ironic it is that the only country in the world that recognizes Electromagnetic Hypersensitivity as a disability would produce such a dreadful vehicle.

For those wondering about hybrids, the numbers are in for a Toyota Highlander hybrid. Radio frequencies emitted from the entire front dash are very strong (measured with an AM radio). The magnetic field (TF2) at the floor is through the roof, and chest level readings are very high. Levels elevate when running on the electric motor. This vehicle also emits pulsed microwaves upon the passengers which may be Blutooth, which can be disabled. If hybrid and electric are the future then ESers are in deep trouble. The only savior is the rear seats have lower levels, so one may resort hiring a driver and sit in the back.

Most alarming is Ford's "Vehicle Hotspot" which blasts the driver with pulsed microwaves. The hotspot can be disabled. Microwaves peak at 6 mW/m2 (0.6 uW/cm2) as measured with the trifield II, and average at about 0.1 - 0.5 mw/m2 standing idle with no connections. The BMW X2 peaks at 4 mW/m2 standing idle, and can also be deactivated via the menus.

Here's the list of low-mid frequency magnetic field ratings of various cars.

Audi -
2011 A4 ** -
Driver: 35.0 milli gauss,
Passenger: 7.0 milli gauss.
Driver Rear: 75.0 milli gauss
Passenger Rear: 4.0 milli gauss

Passenger: 1.3 milli gauss.
Driver Rear: 0.4 milli gauss

Note: Even though the low frequency magnetic field is relatively moderate, the X2 produces strong RF (measured with an AM radio) above head and the headlight switch. These mid-range radio frequencies travel far and can impact the hypersensitive, even if the AM radio is silent at the head. A wireless antenna (internet/wifi hotspot) constantly emits pulsed microwaves peaking at 3.5 mW/m2 with nothing connected. With the hotspot off and streaming music from an iphone the microwaves peak at 6 mW/m2 and average about 2. Electronics never fully shut down in this vehicle, emitting pulsed microwaves when off.

* Measurements were taken with a TriField meter (Frequency Weighted) at the breast of a 5' 10" individual sitting in the seat with all accessories off (including interior light dimmers). The ambient field is negligible. Floor measurements are taken at the calf.

These are not exact measurements, as there can even be a difference in readings between two Trifields. These readings can be used as a guide on the relative strength of the magnetic field emitted by cars.

Most of the magnetic field is produced by the alternator and ignition. Yet something as simple as a dimmed interior light, or a built-in navigation system can cause an elevated field.

** Field increases with engine RPM. Measured at 2200 RPM
