Current RF study at NIEHS

First and foremost, thank you Angela Flynn for keeping your thumb on the pulse and educating us further with the facts.

Below is the link for the information on the current RF study at NIEHS.

I want to point out a few flaws of the study –

The exposure parameters being used in these studies will place the subjects in RF chambers.  In my non professional opinion, this will tell more about our ambient RF exposure than it will about holding RF devices to our heads, which is what the Reps and aides on the Hill thought the study was about when I met with them earlier this year.

The rats and mice will only have ten hours of exposure a day and this does not reflect the 24/7 exposure that many of us find ourselves experiencing.

The study is using  900 megahertz and 1900 megahertz while WiFi and 4G smart phone systems operate at 2.5 gigahertz and higher.

These flaws will probably lead to the same old criticism from industry – that the study exposures are not comparable to our exposures to RF and therefore any results from the study will not be valid.

From the transcripts available at the above link:

The studies at the National Toxicology Program have in fact started. Our studies are designed specifically to mimic the human exposure scenario. The NTP studies are looking at exposures for 10 hours a day. There’s heavy cell phone users that may approach the 10 hour mark – that may be excessive, but it allows us to fully investigate whether or not there is an effect of cell phone frequency radiation.

Our studies are designed to look at the frequencies that are currenly in use in the United States centering around 900 megahertz and 1900 megahertz, as well as the two modulations that are currently in use in the US, which are CDMA (Code Division Multiple Access) and GSM ( Global System for Mobile communications).

There’s been a lot of leg work leading up to the exposure studies. We’ve pulled together some of the world’s experts on radio frequency radiation. We’ve specially designed chambers to expose the animals in. Engineers from NIST, the National Institute of Standards and Technology , have come in to validate the chambers. So, we have third-party validation of the exposures. Additionally, there was a lot of architectural construction that needed to be done at the lab – these chambers are rather large. And they had to be shipped from where they were constructed and designed in Switzerland to our laboratory in Chicago, Illinois.

We estimate that we should have final results from these studies in 2014. We’ll have some interim data available towards the end of 2010/beginning of 2011. .
