Welcome to the group, Ramos!
When a person is already sensitive to EMF, recommended levels for the average person may not apply as we are usually affected at lower levels. I have problems sleeping in an area which is over .6 mG. My current home is less than .1 mG, but it used to go over
6 mG whenever a light was flipped on because of electrical wiring errors.

Powerline (AC) Magnetic Fields. When an appliance is turned on, there will be a powerline magnetic field, due to current, which can be measured by an AC gaussmeter in the unit of the milligauss or microTesla.

Safety Recommendations
Recommended Limit: For long term exposures, it is recommended that the power frequency magnetic field levels be less than
1 mG, or 0.1 μT, according to the Bioinitiative Working Group and the Seletun Scientific Panel recommendations. Some standards go even further, such as
SBM 2008, to recommend even lower values for sleeping areas. The World Health Organization indicates that "pooled analyses of epidemiological studies" demonstrate "a consistent pattern
of a two-fold increase in childhood leukaemia associated with average exposure to residential power-frequency magnetic field above 0.3 to 0.4 μT", which corresponds to 3 to 4 mG. Samuel Milham reports over 50 residential and 100 occupational studies on the
link between power frequency EMF and cancer.
Sperm quality can be lowered by chronic exposures to levels as low as 1.6 mG and chick embryonic development may be affected as low as 1mG.

Health Risks of Power Lines
There are a number of studies, both at the cellular level, and at the epidemiological level, showing potential harm from AC magnetic field exposure.
"We know from studies done at the Cancer Therapy & Research Center in San Antonio, Texas, that our body's defenses are weaker after exposure to EMFs. Human cancer cells grow twenty-four times faster than cells that haven't been exposed to EMFs and show "greatly
increased resistance to destruction by the cells of the body's defense system." (Anne Louise Gittleman, Zapped, 44)
Cellular Studies and Suggested Mechanisms
- DNA Strand Breaks and Genotoxic Effects: Svedentstal et al (1999), Lai and Singh (2004), EU-sponsored REFLEX project
- Cellular stress response found by Martin Blank. Power frequency EMF may induce heat shock protein 70 synthesis in mammalian cells.
- Calcium efflux: Power line EMFs, like microwaves, may cause calcium efflux from brain tissue which could affect neurotransmitters. ELFs can interact with calcium channel proteins in the cell membrane.
- Prolonged life of free radicals may be caused by delaying recombination.
- Reduction of melatonin which is an important free radical scavenger and cancer fighter. See Liburdy et al. 1993, Reiter and Robinson 1995, and Wilson et al. 1990, referenced in
Biological Effects of Low Frequency
Epidemiological and Human Case Studies
- Childhood Cancer: In the 1970s, epidemiologist Nancy Wertheimer detected increased childhood leukemia in children near electric power lines. This was later replicated by Dr. David Savitz. Epidemiology studies suggest link to childhood leukemia at
and over 3-4 mG. Even 1mG chronic exposure can increase cancer risk for children. This may especially affect children with
genetic DNA repair problems. For more information, see Ahlbom et al (2000), Greenland et al (2000), and Mich
- Schuz et al showed that risk for leukemia increased with the higher magnetic fields, when comparing (a) <1 mG, (b) 1-<2mG, (c) 2-<4mG, and (d) >4 mG. Furthermore, the risk for children was much greater than for all ages. A helpful
introduction to the epidemiology by Magda Havas shows the significance of the dose in the risk for leukemia.
- Occupational EMF's and Cancer: Office workers exposed to electronics EMFs were also found to have higher melanoma on covered parts of the body. Occupational studies also suggest that greater EMF exposure results in increased risk of breast cancer.
This included women electrical workers and even the rarer male breast cancer. It has been hypothesized that breast cancer may be related to reduced melatonin production in animals and humans (Reiter, 1995). Melatonin is a major radical scavenger and a great
antidote against cancer.
- Alzheimer's: Certain occupations with stronger exposures (sewing or electrical occupations) carry greater risk, e.g., Alzheimer's for industrial sewing machine operators. A Swiss study showed that people living within 50 meters of a high-voltage
power line had increased risk of Alzheimer's over time.
See Microwave News. The Journal of Occupational and Environmental Medicine reported in 2013 that occupational exposure to magnetic fields may be associated with
moderately increased risk of neurodegenerative diseases such as Alzheimer's and amyotrophic lateral sclerosis.
- IARC type 2B carcinogens (potentially carcinogenic). The National Institute of Environmental Health Sciences (NIEHS) panel of 30 scientists voted 19-8 to identify EMF (Power frequency electromagnetic fields, e.g. 50/60Hz) as type 2B carcinogens,
the same category that lead (as well as coffee) is in. Dr. Marron says, "Now the public will know what the members of the EMF research community have known for years" and yet a lot of the public still doesn't know.
"...a hospital in San Diego, California, found that 14 out of 18 autistic children had lesions in the brain identical to those in rats exposed to EMFs between one and six days after birth." -- (Alasdair & Jean Philips, The Powerwatch Handbook, 178)
- Infertility and Miscarriages: De-Kun Li found men exposed to over 1.6mG for over six hours a day were four times more likely to have substandard sperm and women exposed to over 16mG had higher rates of miscarriages. Li found a strong link between
vacuum cleaner usage and increased risk of miscarriage. (The Powerwatch Handbook, 174). Chick embryonic development is affected as low as 1 mG at 100 Hz (Dr. Delgado in Levitt, 163).
- Depression: Several studies have looked at the potential association between electromagnetic fields and depression (Poole et al. 1993 and DeMatteo 1986, Wilson 1988.) One potential mechanism proposed has been related to disrupted melatonin secretion.Biological
Effects of Low Frequency, p.219.
- Asthma: Maternal exposure during pregnancy may increase risk of
asthma of offspring, with rates of asthma increasing with the magnetic field. (De-Kun Li et al, 2011)
- VDT's: With the older CRT monitors, there have been studies of birth defects of children of CRT computer users (Levitt, 169). Olle Johansson's research has found biological effects of CRT monitors on both healthy people and people with electrohypersensitivity.
These relate to the skin and the immune system. Magda Havas also looked at her own blood and observed blood clumping after roughly 70 minutes of computer work. See
Live Blood Cells and Electrosmog . Fortunately, she said it returned to normal within 10 minutes after computer use.
- Attracting Toxic Gases: Electricity pylon towers might also attract certain toxic gases, such that living within the air current of one of them may not be such a good idea either

Subject: [ES] Help with EMF safe levels in my Room / house
Hello everyone, i'm new in this forum and i recently got a Meterk EMF Meter, i have seen that i had a analog meter in the same wall as in my room and it was not working, but it was on, fixed that problem, but i can't detect much mG in my house, around
0,3 - 3,0, is it dangerous? I wanted to know what is a good level of mG to stay without health problems.
Thank you all!
