Ford EMF Measurements of Cars and Trucks PDF Manual Reference

Some specialty vehicles were measured. That a hybrid car shows up high is no surprise, and it probably would really light up when moving. Hybrid cars are partially electrically driven and have a lot of power-handling equipment on board, which a gaussmeter does not measure well. The author found this car the most bothersome to drive of all vehicles tested. The number of cylinders in the engine do not seem to be significant which is surprising as there are more spark plugs to fire. Perhaps the reason is that the extra cylinders tend to be further from the driver. The table does not show any measurement for the Prius with a revved up engine, as the computer control refuses to do that at a standstill.

The 1966 Volkswagen has the engine in the back and shows nice low numbers. Had the car been longer, it would have shown much better numbers yet. The EMF measured came largely from the battery cable under the rear seat, and the ignition key. The best gasoline-powered cars are the 1987 Dodge Aries Wagon and the 1991 Cadillac Sedan deVille . The 1982 diesel Mercedes came in as the overall best, when the alternator and cruise control were disconnected. At those low levels, EMF from the speedometer and other moving pars become dominant when the car was running. With further work, that car got down to only 0.02 milligauss. More recent diesel vehicles are unlikely to get as good, as they have more electronics, including electronic fuel injectors.

For each vehicle, up to ten measurements are shown. The numbers are in the unit miligauss (10milligauss = 1 microtesla). The columns correspond to the eight locations, as shown on the diagram. Location 1 and 4 are done twice; with the engine idling and with the engine revved up. Test point 1 through 7 are places where a driver would be exposed while driving the vehicle. For most people, the highest reading is the most significant. Some electrically sensitive people may be more sensitive in some body parts than in others. In that case, give more weight to the appropriate measurement point. Point eight is only of interest if a sensitive person is largely going to be a passenger, In that case, the back seat is usually better anyway.

The highest rating for any vehicle is usually test point 1, with eh engine revved up. This is the gas pedal, where the right foot will receive the measured level of EMF exposure continuously, while driving the car, unless using cruise control. However, cruise control can be problematic in itself. Looking over the tables, a pattern emerges, with trucks tending to have lower readings that cars, Great variation is seen between models of trucks, however. Two model-years of the Ford F-150 V6 truck have very different values, with the 1993 model showing 35 milligauss as the highest reading, while the 2000 model only shows 7 milligauss. The F- 150 was redesigned between those model years. The best truck is the Dodge Dakota V8 from 1997, with many close contenders.
