Default Israel radiation study

What do you guys think about this?

Do Hybrid Cars Emit Excessive Radiation? | Sustainability | Fast Company

I have no idea if it's a totally legit study or not. Anyone well versed on the subject? I'm wondering what these numbers mean in comparison to household equipment, like CRT monitors, microwaves, etc.

Well, if anyone is an expert on hybrid car battery radiaton, Israel would be my last guess.

I think it is likely hogwash. The only type of radiation I can imagine one would be exposed to in a hybrid is electro-magnetic radiation. Well, I just had an MRI done a few days ago in a 1.5-tesla machine. That thing has a magnetic field millions of times higher than anything a hybrid car could hope to produce and those have been deemed completely safe. Even cell-phones that produce microwave radiation (which actually could damage living tissue if the power level were high enough) probably produce more radiation than a hybrid.. and numerous studies have shown those to be safe too.

Post Will look into this with what I have on hand

Does anyone know what type of guass meter they used? I have an ELF guass meter and own 2010 Insight EX (no navi). I can test but typical guass meters are optimized for a frequency of around 60hz. I doubt the Insight electromagnetic field emanations operate at 60hz. I will however use what I have and see what I can see ASAP.

Why is that? With more than 3,000 high-tech companies and start-ups, Israel has the highest concentration of hi-tech companies in the world (apart from the Silicon Valley).

Interesting why the hybrid vehicles are made by companys in Japan.

Post ELF measurements

2010 Insight EX (no navi) using Gauss Meter type F. W. Bell ELF Model 4060. Tested driving, all areas including up against back seat down in foot well (near pedals). Tested while forced charge and naturally occuring charge.
Worst static (constant) measurement was along the floor shifter mechanism @ 2 milliGauss. Sometimes this would jump for a second to 4 or even 5 milliGuass and return just as fast to 1 milliGauss. This meters range is typically 0hz - 3khz and optimized for 60hz readings. While not a full range meter, ELF Extremely Low Frequency and VLF Very Low Frequency radiated emissions are more penetrating than RF type radiation. The magnetic component of RF generally falls off below 300mhz. So the study done was probably finding RF levels of radiation.
We are exposed to massive amounts of RF from a great many sources. From an ELF point of view, using a limited measuring tool, the 2010 Insight appears to fall within specified ELF/VLF safe levels. A typical power "wall wart" puts out anywhere from 50 milliGuass to hundreds of milliGauss when measured. The F. W. Bell ELF Model 4060 was able to measure Kitchen Microwave, Wall Warts, all AC ELF producers and some forms of lower power DC like 1milliGauss from my non-powered up/non-plugged in laptop, however it is unable to measure over the entire electromagnetic spectrum. Here is an incredibly detailed reference on this subject:

http://www.inspectapedia.com/hazmat/...MF_Hazards.pdf

I have used my ELF meter to walk away from a few prospective home purchases in the past so given its 2010 Insight readings are acceptable to me I will be having no issues keeping and using my car. Admittedly however if the ELF was off the scale I would have had to do something about this. I would like to see the full details of the formal testing released. I want to know if they tested for source of RF with a spectrum analyzer when they got the high readings. The test would have had to be done similar in form to FCC/CE mark emissions testing compliance, in other words, to be credible. When home buying I don't test for anything above the F. W. Bell ELF 4060 meter's range.

If anyone has the thousands of dollars of equipment required to test the full spectrum of emissions, in the right kind of eletromagnetically silent environment required, please test and let us all know the findings. Don't forget to pipe the exhuast outside, so you don't sufficate yourself due to the required running engine for the full testing. Don't forget the spectrum analyzer with/audio function so you can ensure its not a radio/TV station or other similar if you get a high reading.

I have no association with F. W. Bell other than owning their product.
I have no association with Honda other than owing their product.
I have no association with FCC or CE Mark related standards or testing.
I have no association with inspectapedia.com

I can provide picture proof of my findings.

Please don't sue me. I am simply stating my obervations and personal feelings. I still absolutely love my 2010 Insight.

Post ELF measurement correction

I meant the magnetic component of RF generally falls off ABOVE 300mhz. So the study done was probably finding RF levels of radiation below 300mhz if there was a magnetic gauss component measured. Without full details again regarding how the study was done we will never know if it was credible, what it all means at the end of the day etc...

Thanks for doing that! I would have had no idea how to. I too would have been concerned if you had very high readings. Almost every type of cancer runs in my family, so I don't really like to tempt fate. I'll definitely keep an eye out for the formal results being published.
