Discussion Overview

The discussion centers on the safe levels of Gauss (magnetic field strength) for human exposure, particularly in everyday environments. Participants express confusion over conflicting information regarding acceptable exposure levels and the potential health effects of electromagnetic fields.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants note that there is no consensus on safe levels of Gauss for everyday exposure, with one participant stating a human limit of 2000 Gauss.
  • One participant argues that there is skepticism regarding the biological effects of low-energy electromagnetic fields, suggesting that such fields do not have enough energy to break hydrogen bonds, which is necessary for biological effects.
  • Another participant mentions that their cell phone emits 98.2 Gauss, highlighting variability in reported exposure levels.
  • A participant references studies by Stick and Hinkelmann, which claim that magnetic fields up to 1 Tesla (10,000 Gauss) have no effect on biological tissues, indicating that everyday magnetic fields are too weak to cause effects.

Areas of Agreement / Disagreement

Participants generally agree that there is a lack of consensus on safe levels of Gauss and that conflicting information exists. Multiple competing views regarding the health effects of electromagnetic fields remain unresolved.

Contextual Notes

Limitations include the absence of clear definitions of "safe levels," the complexity of biological processes, and the reliance on varying studies that report different findings.

All the articles and books I have read conflict with one another in safe levels of Gauss. I understand the Human limit is 2000 Gauss. Does anyone know what levels of Gauss are acceptable for everyday exposure? As I said, all reports I have read conflict one another.

The reason there is no consensus as to what level of electromagnetic field is safe is because there is really no evidence that em fields are a danger to human health.

Although all biological processes are complex, there is every reason to be very skeptical that low energy em fields cause any biological effects. In order to have a biological effect, an em field, at a very minimum must be able to break a hydrogen bond. Compare the bonding energy of a hydrodgen bond to the energy of a photon radiating from a powerline, for example. The heat energy in a cell, which is essential in order for biological processes to operate, produces much higher energy photons.

I have found the same thing, I have not found two sources that say the same thing as far as what is safe. My cell phone puts out 98.2G (using a LakeShore 410 Gaussmeter).
 
Biological studies by Stick and Hinkelmann of the effects of static magnetic fields have found that magnetic fields up to 1 Tesla (10,000 Gauss) have no effect on tissue, blood flow, etc. One Tesla is huge. You only get magnetic fields like that in special medical machines (MRI) or in special laboratories specifically designed to create fields that strong. If you ever find yourself near such things, you are briefed on the potential risks of strong magnetic fields. Although most biological tissue is diamagnetic, the response is so weak that everyday magnetic fields, such as from a cell phone, loud speakers, or fridge magnets are far to weak to have any effect.
