Mobile Phones – the Truth

Safety advice

How long is it safe to call?

The radiation from mobile phones is thousandfold stronger than the intensity that causes a measurable impact on your cells and tissues. Therefore, even a short call can be harmful.

Three major kinds of hazards arouse especially great concern:

  1. DNA damage. It is well establised that the DNA is damaged by mobile phone radiation. The stronger the intensity the greater the damage. It is also well known from the study of radioactivity, which damages DNA in a similar way, that the effect is cumulative. DNA damage increases the risk for cancer. Also it has been demonstrated to damage germ cells in the reproductive organs, increasing the risk for sterility.
    • Safe exposure time: No safe minimum has been established. The risk for a harmful effect is small with a short call and increases over time. So if you want to minimize DNA irradiation damage, never make long calls. For safety, to minimize the damage to your DNA, the shorter calls, the better.
  2. Blood-Brain-Barrier damage. A Swedish research team lead by professor Leif Salford, neurosurgeon, found that this barrier, which protects the brain from inflow of harmful substances from the bloodstream, was disrupted by mobile phone microwaves at levels occurring during normal calls. It is known that this barrier is damaged in Parkinsons disease and in Alzheimers dementia. So there is a risk that disruption of this protection barrier may damage the brain.
    • Safe exposure time: Maybe maximum 2 minutes, possibly less. The disruption of the BBB occurred in Salfords experiments within 2 minutes, in some cases even sooner. The effect was greater, the greater the intensity of the radiation.
  3. A general disturbance of the physiology including brain function and heart function. Depressions, sleep disturbances, concentration difficulties, memory disturbances, heart rate irregularities have been reported. Stress burnout may be a consequence. This effect seems to affect all people to a greater or lesser extent and it has been reported at low radiation intensities. Accumulating research data indicate with increasing strength that this is a major public health issue.
    • Safe exposure time: No safe minimum has been established. The longer the call the greater the impact. For safety, minimize exposure time.


A. Minimize time and and intensity

In short:

  • Make only brief calls – seconds, not minutes – at minimum radiation.
  • Turn off the phone whenever possible.
  • Minimize stand-by time to situations only when you must be immediately accessible..
  • Keep it away from the body when on stand-by.


  1. Minimize the time you speak. This is because the risk for damage increases the longer you speak. Preferably use the mobile only for very short messages, of a few seconds length, never for several minutes.
  2. Minimize the intensity of the irradiation. This is because the risk for harmful damage increases the stronger the intensity.
    • Avoid calling when the signal is weak (as indicated on the phone screen), because then your mobile will irradiate maximally in order to be able to reach the station.
    • Avoid speaking in elevators and other confined places, because there the irradiation is especially strong (the metal walls reflect the microwaces and also a much stronger signal from the mobile phone is needed so as to reach out through the shaft).
    • Avoid speaking in busses, trains, trams, subway/underground vehicles etc. A Japanese study found a considerable increase of radiation in trains because the radiation was reflected inside the space due to the metal walls. The same goes for all vehicles.
    • Hold the phone as far away as possible from the head while calling. The intensity of the radiation decreases rapidly with distance (with the square of the distance). For this reason:
      • Use safe headsets. It seems that the kind ha a plastic tube between the earpiece and the phone are best. Search on Google for tube + headset (or airtube) and you will find several alternatives.
      • Use a loudspeaker phone, as your headset may not not always be available.
  3. Minimize the exposure of the body to irradiation. This is because the body absorbs the harmful microwaves much better than the skull. Therefore don’t carry an active mobile phone in a pocket or clipped to the belt. Professor Olle Johanson had a case who developed cancer in the body exactly beneath the place where the mobile phone was clipped on to the belt. So far no research has been published to our knowledge about such cases but we would expect a significant connection in the same way as brain tumors develop close to spot where one holds the mobile phone.
    • Switch off the mobile phone when you don’t call
    • Rethink your priorities regarding accessibility. If it is not of vital importance that you need to be reached immediately, switch it off. In stead check your calls regularly and call back in some place where the signal strength is excellent.
    • If you must keep it on stand-by, don’t carry it close to the body. Develop the habit of putting it in a handbag, briefcase or the like
    • In the car, use a hands-free set that enables you to put the mobile phone as far away from the body as possible and most preferably uses an antenna mounted on the outside of the car.
  4. Because free radicals are generated by the radiation, food and food supplements that quench free radicals, so called antioxidants reduce the risk for radiation damage to DNA, but it has not been established scientifically to what extent they can protect. Oxidative stress is also the probable cause of the above mentioned microwave-induced leakage through the Blood-Brain-Barrier. It has been amply documented experimentally that oxidative stress causes permeability of the BBB. In any case, if you are using mobile phone much, it is advisable to take as much antioxidants as possible (see posting on prevention of Alzheimer). It is not clear to what extent antioxidants protect against the microwave-induced psychophysiological disturbances, but it has been amply documented that oxidative stress play an important role in mental disorders including depressions, manic disorder, autism and shizofrenia.

B. Avoid other sources of microwave radiation

  • Keep out of WiFi fields. If you have WiFi-based internet at home, get rid of it and use cable connection (ethernet). Until you find a replacement, switch the WiFi off when not used. Some studies indicate that the WiFi irradiatoin is stronger than the producers maintain. And it is contiuous. Don’t stay long in WiFi cafés. Don’t take jobs where the internal network is WiFi-based. We are aware that this is becoming increasingly difficult, but by putting your attention on this, you can hopefully reduce the expostion significantly.
  • Don’t use cordless phones anywhere and especially not at home. Their “base station”, the charger/antenna, emits strong and continuous microwave radiation throughout the whole house 24 hrs a day. Throw the cordless away and use ordinary landlines only.
  • Keep out of Mobile phone towers / base stations. Studies indicate an increased rate of diseases, including cancers, within about 400 m from them.

NOTE: New mobile phone antenna solutions are underway that can reduce the exposure greatly perhaps to zero. Look out for them and get one as soon as possible

Please note that these measures don’t eliminate the risk, they only reduce it.

Bottom line

The only safe way to prevent harm from this radiation is to minimize the use the mobile phone as well as to minimize the exposure to Wifi-systems and Mobile phone towers.
