Permeability of the Blood-Brain Barrier Induced by 91 5 MHz

Electromagnetic Radiation, Continuous Wave and Modulated

at 8, 16, 50, and 200 Hz

ABSTRACT Biological effects of electromagnetic fields (EMF) on the blood-brain barrier (BBB)

can be studied in sensitive and specific models. In a previous investigation of the permeability of the

blood-brain barrier after exposure to the various EMF-components of proton magnetic resonance

imaging (MRI), we found that the exposure to MRI induced leakage of Evans Blue labeled proteins

normally not passing the BBB of rats [Salford et al. (1992), in: Resonance Phenomena in Biology,

Oxford University Press, pp. 87-911.

In the present investigation we exposed male and female Fischer 344 rats in a transverse elec-

tromagnetic transmission line chamber to microwaves of 915 MHz as continuous wave (CW) and

pulse-modulated with repetition rates of 8,16, 50, and 200 s-’. The specific energy absorption rate

(SAR) varied between 0.016 and 5 Wlkg.

The rats were not anesthetized during the 2-hour exposure. All animals were sacrificed by

perfusion-fixation of the brains under chloral hydrate anesthesia about 1 hour after the exposure.

The brains were perfused with saline for 3-4 minutes, and thereafter fixed in 4% formaldehyde for

5-6 minutes. Central coronal sections of the brains were dehydrated and embedded in paraffin and

sectioned at 5 pm. Albumin and fibrinogen were demonstrated immunohistochemically.

The results show albumin leakage in 5 of 62 of the controls and in 56 of 184 of the animals

exposed to 915 MHz microwaves. Continuous wave resulted in 14 positive findings of 35, which

differ significantly from the controls (P = 0.002). With pulsed 915 MHz microwaves with repetition

rates of 200,50, 16, and 8 s-l, 42 of 149 were positive, which is highly significant at the P = 0.001

level. This reveals that both CW and pulsed 915 MHz microwaves have the potential to open up the

BBB for albumin passage. However, there is no significant difference between continuous and

pulsed 915 MHz microwaves in this respect.

The frequency of occurrence of extravasates (26%) was found to be independent of SAR for SAR

< 2.5 W/kg, but rose significantly for the higher SAR values (to 43%).

The question of whether the opening of the blood-brain barrier constitutes a health hazard

demands further investigation.

THE GENERAL PROBLEMS OF EMF INVESTIGATION CONCEPT OF INFORMATION SUPPORT FOR MOBILE PHONE USERS SAFETY ON THE BASIS OF PRECAUTIONARY POLICY REALISATION IN PUBLIC HEALTH SERVICES. Grigoriev O.A.1, Vasiliev O.A.2, Bichelday E.P.1 1National fund for non-ionizing radiation protection, Moscow, Russia 2Russian Ministry of public health department for State epidemiological inspection, Moscow, Russia Mobile telecommunication is rapidly developing as an element of social technological infrastructure. However none of the specialised scientific organisation could confirm, that mobile phones EMF is unharmful for human health. Numerous researches reveals more questions than answers. World health organisation consider, that the consequences from mobile phones’ EMF exposure of individuals as well as human population in whole aren’t known enough , therefore we have to continue the scientific researches and provide the precautionary policy. According to precautionary principle we have to make all efforts to decrease the risk for human health, even finally unproved. Mobile telecommunication systems drastic increasing, though we have no final results of EMF biological influence researches. It means that mobile phones’ value for society is more important factor, comparing with real and possible risks for human health. Refer to the law project “About the basis of technical regulation in Russian Federation” sellers should provide goods safety for consumers, this means that mobile phones’ sellers and manufactures have to confirm their equipment safety. However it takes time to adopt the law and work out the mechanism of its realisation. In such conditions we consider that the most actual and rather fast method to provide the population safety is let to know the objective and actual information that allows to generate own opinion and make realised choice in all aspects of the problem «Mobile phones and health». Such programs should be aimed to mobile phones services’ consumers (voluntary risk group) as well as to other population…

Randomized double-blinded placebo controlled trials (or equivalent) are needed to determine the effects of EMF’s on biological life, specifically nnEMF’s. I strongly recommend that a moratorium be put in place for ANY technologies that emit EMFs to any degree, and current technologies be disabled. I agree with Katherine Watt’s assessment below.

“I tend to think 5G, 4G, 3G and other (novel or renamed old) EMF sources are useful for 1) wasting

human time and material resources (construction projects with no real benefit or improvement over

existing tech); 2) frightening people/inducing sense of helplessness about potential sources of harm

they cannot readily see or avoid; and 3) deflecting attention away from global theft

(looting/hoarding of land and resources) and from biological and chemical poisoning (vaccination,

drugs, low-altitude outdoor and indoor/interior-of-building sprays, derailments, explosions) as

primary causes of sickness.”

Long-term residential magnetic field exposure and neurodegenerative

disease mortality: An 18-year nationwide cohort study in Switzerland

2026

A B S T R A C T

Background: Epidemiological evidence on the association between extremely low-frequency magnetic fields (ELF-MF) exposure and neurodegenerative diseases (NDD) remains inconsistent. Few population-based studies using exposure from high-voltage power lines (HVPL) have found mixed findings, and none have yet considered exposure from railway lines.

Methods: We followed 3,555,064 adults from the Swiss National Cohort (2001–2018), contributing 55.4 million person-years. Long-term ELF-MF exposure from HVPL (50 Hz) and railway lines (16.7 Hz) was modelled using validated proximity models and updated over four intervals (2001–2005, 2006–2010, 2011–2015, 2016–2018). Long-term ELF-MF exposure was calculated as a time-weighted average exposure over 10-year windows preceding each interval. Cox proportional hazards models estimated hazard ratios (HRs) for mortality from Alzheimer’s disease (AD), other types of dementia (OTD), amyotrophic lateral sclerosis (ALS), Parkinson’s disease (PD), and multiple sclerosis (MS), adjusting for sociodemographic and environmental co-exposures.

Results: During follow-up, 146,655 NDD deaths occurred. Less than 1% of the population was exposed to long-term ELF-MF ≥0.3 µT from HVPL and 2.4% from railway lines. HVPL exposure was positively associated with mortality from AD (HR per 1 µT increase in exposure =1.54; 95% CI: 1.23–1.92) and OTD (HR =1.31; 95% CI: 1.13–1.52). Associations for railway exposure were weaker and attenuated after adjusting for environmental co-exposures. No associations were observed for ALS, PD, or MS.

Conclusions: Long-term ELF-MF exposure was associated with higher dementia mortality risk in the general population, but not with ALS, PD, or MS. Causal inference remains limited by the absence of established biological mechanisms.

The Possible Role of Contact Current

in Cancer Risk Associated With

Residential Magnetic Fields

2000

Residential electrical wiring safety practices in the US result in the possibility of a small voltage (up

to a few tenths of a volt) on appliance surfaces with respect to water pipes or other grounded

surfaces. This ``open circuit voltage'' (VOC) will cause ``contact current'' to flow in a person who

touches the appliance and completes an electrical circuit to ground. This paper presents data

suggesting that contact current due to VOC is an exposure that may explain the reported associations

of residential magnetic fields with childhood leukemia. Our analysis is based on a computer model

of a 40 house (single-unit, detached dwelling) neighborhood with electrical service that is

representative of US grounding practices. The analysis was motivated by recent research suggesting

that the physical location of power lines in the backyard, in contrast to the street, may be relevant to

a relationship of power lines with childhood leukemia. In the model, the highest magnetic field

levels and VOCs were both associated with backyard lines, and the highest VOCs were also

associated with long ground paths in the residence. Across the entire neighborhood, magnetic field

exposure was highly correlated with VOC (r 0.93). Dosimetric modeling indicates that, compared

to a very high residential level of a uniform horizontal magnetic field (10 mT) or a vertical electric

field (100 V/m), a modest level of contact current ( 18 mA) leads to considerably greater induced

electric fields (> 1 mV/m) averaged across tissue, such as bone marrow and heart. The correlation of

VOC with magnetic fields in the model, combined with the dose estimates, lead us to conclude that

VOC is a potentially important exposure with respect to childhood leukemia risks associated with

residential magnetic fields. These findings, nonetheless, may not apply to residential service used in

several European countries or to the Scandinavian studies concerned with populations exposed to

magnetic fields from overhead transmission lines. Bioelectromagnetics 21:538±553, 2000.

A Narrative Review on the Influence of Electromagnetic Fields

Below 100 kHz on the Endocrine System

2026

Abstract

Background: Extremely low-frequency electromagnetic fields (ELF-EMFs), generated

mainly by power infrastructure and household devices, have raised scientific interest

due to their potential impact on the endocrine system. Animal research consistently shows

effects on melatonin secretion, stress hormone levels, thyroid activity, and reproductive

function—largely mediated by oxidative stress and calcium ion imbalance. In contrast,

human studies remain inconsistent, often hindered by methodological limitations and

insufficient exposure characterization. Objective: This review synthesizes experimental

and epidemiological studies examining low-frequency electromagnetic field exposure

(≤100 kHz) and its influence on hormonal regulation. Methods: A bibliometric analysis

highlights focused interest on specific endocrine targets, particularly the pineal gland.

Importantly, many experimental studies use field strengths above those found near high-

voltage power lines, limiting direct applicability. Conclusions: While a definitive causal

link has not been established, the widespread exposure to low-frequency electromagnetic

fields justifies precautionary considerations. Several important research gaps remain, many

of which are identified in this review. The topic of low-frequency electromagnetic field

effects on the endocrine system requires more rigorous, long-term human studies with

accurate exposure assessment.

Mobile telephony radiation exerts genotoxic action and significantly

enhances the effects of gamma radiation in human cells

2024

Abstract. I previously reported chromosomal damage in human peripheral blood lymphocytes

(HPBLs) induced by: a) mobile telephony (MT) electromagnetic fields (EMFs)/electromagnetic

radiation (EMR), b) a high caffeine dose, and c) the combination of the two stressors. HPBLs

from the same subjects exposed to gamma radiation at doses 0.1, 0.3, or 0.5 Gy, displayed more

aberrations than those exposed to MT EMFs or the high caffeine dose in a dose-dependent

manner. When the cells exposed to these gamma radiation doses were pre-exposed to a single

15-min MT EMF exposure, the number of aberrations increased significantly more than the

sum number of aberrations induced by the individual stressors in all subjects. Thus, MT EMF

exposure at a power density ~136 times below the latest International Commission on Non-

Ionizing Radiation Protection (ICNIRP) exposure limit, apart from the fact that it is genotoxic

by itself, significantly enhanced the genotoxic action of gamma radiation. Since gamma radiation

at similar doses is applied for diagnostic and therapeutic purposes, people should be aware of the

increased risk during treatment periods. Comparison of the genotoxic action between MT EMF

and gamma radiation shows that the ICNIRP limits are, at least, ~4.5×104 times less stringent

than the limits for gamma radiation.

Mobile phone affects cerebral blood flow

in humans

2006

Abstract

Mobile phones create a radio-frequency electromagnetic field (EMF) around them when in use, the

effects of which on brain physiology in humans are not well known. We studied the effects of a

commercial mobile phone on regional cerebral blood flow (rCBF) in healthy humans using positron

emission tomography (PET) imaging. Positron emission tomography data was acquired using a

double-blind, counterbalanced study design with 12 male subjects performing a computer-

controlled verbal working memory task (letter 1-back). Explorative and objective voxel-based

statistical analysis revealed that a mobile phone in operation induces a local decrease in rCBF

beneath the antenna in the inferior temporal cortex and an increase more distantly in the prefrontal

cortex. Our results provide the first evidence, suggesting that the EMF emitted by a commercial

mobile phone affects rCBF in humans. These results are consistent with the postulation that EMF

induces changes in neuronal activity.

My name is Brittany Harris my anatomy has gone through years of torture from scalar ways and radio frequencies, and subliminal messaging. It started in year 2016 and got way worse in year 2022. My face is constantly being burned, my lower belly regions, genitals are nonstop targeted by these weapons. I've cried for help every day , so far I haven't found anything to block or shield my anatomy from being targeted by these waves, and lasers.

These systems are being used to attack innocent Americans all across the county in a targeted operation. We’re being lied to about the health effects of low intensity, long duration, exposure to EMF, EF, radio, and microwave radiation. Parts of the federal government are either complicit or assisting in these attacks against Targeted Individuals and their families

Ban it all! If God wanted us to use radios he would have put one on the Ark!!!

I had began receiving Havana Syndrome like symptoms upon receiving my equipment from the Pittsburgh CDC location for a job as a contractor at the CDC. I experienced symptoms related to psychosis and felt that I was a targeted individual - someone who experiences V2K and is harassed by a mob of people. My router was acting funny as well - https://www.amazon.com/gp/aw/d/B09G5W9R6R?psc=1&ref=ppx_pop_mob_b_asin_title - and I began receiving odd search results through linked router. I was able to work fulltime as a contractor but due to the work environment as well as my brief psychosis but somewhat believe I was being studied. I previously had a galaxy s20 I believe as well as Iphone 13 max, both 5G related phones in my tenure as a contractor there. I never received treatment and symptoms relieved after quitting the position.

Technology can be wonderful, however we need to move forward in thoughtful ways because it can also be harmful, not just to people, to animals and plants too. There needs to be real limits on wireless radiation exposure; look at the differences between USA and Europe when it comes to various radiation and EMF exposure limits, theirs are much stricter; I think we can improve things in the USA and seriously take into account how people are actually using technology, don't just limit per device or hazard, there needs to be an overall exposure limit because most people will have multiple devices and hazards around them all the time. There are also various mitigating coatings, containers, or other things that can mitigate exposure from the devices and hazards themselves, these mitigations need to be more common place as we advance technologically speaking. It does no good to have the best computing power when everything around it suffers. In conjunction with this, with the rise of data centers and other technological infrastructure, we need to also use mitigating factors there too for not just wireless radiation exposure, also sound and vibrational overexposure. These buildings and complexes have a constant hum so-to-speak, this disturbs everything around it, from the people, plants, animals. We need to look out for all of us on this planet while we advance our civilization and keep the world beautiful for all of us.

I think everyone knows this is incredibly harmful to humans and animals. The sad truth is it is a very simple fix, but to do so costs money and these companies would have to admit they harmed us.

I can no longer work because of the towers everywhere in Coeur dalene Idaho. They are everywhere. We see you are trying to kill us.

Where are the FCC reports of monitoring them? I believe that they are harmful but more so when guideline established are not tested. Show me the paperwork please.

My name is Robert Wesley Baird. I've been getting hit with directed energy weapons for 16 years. We need serious help! Thank you for your time.

With more Wi-Fi being included with personal items in our homes, from our alarm systems to our HVAC systems and everything in between, how do we know how much we're ultimately being exposed to? We had a Wi-Fi smart meter removed from our power panel because it sits directly beneath our master bedroom, which means that we are being exposed to Wi-Fi all night long while we are sleeping. But we have to PAY an extra fee to not be radiated by our smart meter every month. And yet, the power company has NO RESPONSIBILITY to ensure that their Wi-Fi meter is safe for our health. There are so many issues that have yet to be addressed and I strongly urge this administration to fully research the safety of all these technologies.

I have been negatively affected by wireless radiation. I had to leave my medical career due to not being able to work with all the wireless infrastructure surrounding me.

Please take steps to lessen the toxic nnEMF in workplace environments, schools and neighborhoods.

Thank you for taking the time to read my comment.
