Is PEMF really safe?

Or does PEMF cause cancer???

Confused? You are not alone: many things are going on in respect to safety of PEMF's compared to EMF’s. GenuineReal PEMF devices (like the Parmeds PEMF devices) generate pulsed frequencies under 100 Hz and are classified as Extremly Low Frequencies (ELF).

PEMF's are extremely low frequency pulsed fields with a range from 1 Hz to 50 Hz.

Power lines

Electro-Magnetic Fields (EMF) should not to be confused with 50 or 60 Hz electromagnetic radiation which occurs around high voltage power lines and transformers and create a continuous electromagnetic field. 

The effects these electromagnetic fields have are completely different from PEMF's and the warnings should be taken seriously because they are right! 

Diathermy device

Diathermy short wave treatment devices are used in clinics and hospitals for internal body warming. These devices are called Short Wave Diathermy and work on a frequency of 27 MHz (27.000.000 Hz).  

Exposure to these frequencies over extended times is harmful and because of this treatment time should be kept short.

High frequencies (cell phones) use carrier frequencies higher than 800 MHz (800.000.000 Hz) and it is still questionable if these frequencies will cause cancer. Further discussions will take many more years before any conclusions can be drawn. At the current time there is absolutely no proof that these frequencies may stimulate cancer growth and recommendations are currently not to let children use cell phones for long time periods because these devices are held close to the brain, which is still under development at young age. 

Microwave ovens operate on frequencies around 2.45 GHz (2.450.000.000 Hz) and are harmful if applied directly to eyes and testis because blood flow in these organs is limited and as such cannot "cool off" the heating effect.

This is why a microwave oven stops working when the door is opened while the device is working, to avoid danger. Heating of the food happens because of friction of the agitated molecules.

Conclusions: Low frequency PEMF is completely safe and will not cause cancer as long as the pulsed frequencies are lower than 100 Hz, as is the case in the Parmeds devices. PEMF devices generating higher frequencies are definitely dangerous and use of such devices should be avoided!
