Does anyone have a good understanding of the dangers of various medical scans for EHS persons? I'd like to get a better understanding of what tests are safe for people to undergo. I have heard that CT scans are diabolical because they are like a hundred xrays all in one hit. And then I was reading that MRIs give the patient a huge dose of magnetic fields and that scares the crap out of me. Does anyone know if OPGs (full mouth dental xray) are the dental equivalent of a CT scan or are they safer than a dental Xray or a little worse? What tests/scans are safer alternatives? It would be great to get something like a hierarchy of worst to best types of scans though I guess they are not all going to fit neatly into such a framework.
Dentistry and CT utilise X-rays, while MRI is wholly magnetic. Exposure varies according to the make and model of equipment, and part of the body being diagnosed. The latter also relates, in terms of potential damage, to the susceptibility of included organs. It is thus impractical to generalise potential effects based upon the single parameter of dosage.
Nonetheless, below are a few figures based upon averages. Please consult your doctor for accurate information.
Dental - 0.005mSv each, 0.1mSv full head
Chest - 0.1mSv
Mammogram - 0.4mSv
Abdomen - 0.7mSv
CT scan (full):
Head - 4-5mSv
Abdomen - 10-20mSv
Natural background radiation is 2-3mSv per year.
Earth's natural magnetic field is 2.5 to 6.5 Gauss
Wow, thanks EMRTechie. That's helpful info.
An additional source of X-rays, and general cosmic radiation, is air travel. The dose received relates to flight duration, altitude and latitude. For comparison, a trip from New York to Tokyo equals about 1/30th of a chest X-ray.

However, onboard Wi-Fi and use of devices by fellow passengers are undoubtedly of greater import to EHS. To minimise exposure, I find the best place is a window in the last row. This is usually away from the centrally situated modems, and has fewer adjoining seats. Being at the outer periphery also avoids, in part, the concentration of RF along the centre axis of the curved metal fuselage.
For prospective passengers who wish to avoid Wi-Fi, this is a list of commercial airlines that do and do not have it. https://www.finder.com.au/list-of-airlines-with-wifi
What do people make of this guest post on Lloyd Burrell's website https://www.electricsense.com/14745/ultrasound-pregnancy-risks/ ?
If this is accurate then it's additional fuel to ensure world de-population. If you can't successfully decrease people's fertility via EMR exposure, then surreptitiously kill off the foetus, all in the name of 'we're helping you'.
Remember, it's not only pregnant women who have ultrasounds.
That's pretty scary TMBL - thanks for sharing. My research shows that a CT scan is equivalent to 200 chest x-rays or 1500 dental x-rays and an MRI is not just magnetic waves but also radio waves i.e. radio frequency radiation!!! I thought ultrasound was relatively benign but now I see that idea is wrong.
I remember seeing an ultrasound of my grandson before he was born and every time a wave hit him he jumped. It was very disturbing to watch. It was like he was being pummelled or attacked. These days pregnant women do ultrasounds to determine the sex of their baby - they can't wait till the baby emerges and choose to assault their unborn instead. I'm sure it's ignorance on their part ... if only they knew what Lloyd Burrell knows they might choose not to have ultrasounds.
It was recommended to me to have a Thermogram which appears to be totally harmless consisting of infrared photographs taken of you over about 45 mins.
You are not alone. According to certain experts, over 35% of the world’s population feels some form of unwanted reaction to EMR exposure. Additionally, everyone is susceptible to induced biological abnormalities that may not manifest perceptibly for years or even decades.
