All electronic devices contain information which warns against keeping your device in direct contact with your head or body.[1] Few people are aware of this and even fewer follow the instructions provided.

Non-ionizing (electromagnetic) radiation or NIR is omnipresent. Mobile phone users in particular should be aware that electronic devices emit non-ionizing radiation, which may have some negative effects on their health.[2]

Lower frequency radiation is generated by a laptop’s internal parts, such as the hard drive.
Higher frequency radiation is emitted by the transmitters of the laptop when it tries to connect with a WiFi network, wireless devices or Bluetooth receivers.

Non-ionizing radiation is located at the low end of the electromagnetic spectrum and is a form of low-energy radiation. This kind of radiation is also known as extremely low frequency (ELF) radiation. Non-ionizing radiation differs from ionizing (IR) radiation because non-ionizing radiation doesn’t carry enough energy to break molecular bonds and ionize atoms, ionizing radiation does.

We are in the midst of a paradigm shift when it comes to our understanding of the biological effects of non-ionizing electromagnetic frequencies generated by our use of electricity, electronics and wireless technology. Ionizing radiation (IR) has enough energy to break chemical bonds and is known to cause cancer. However, because nonionizing radiation (NIR) lacks this energy, it was assumed that these lower frequencies cannot be carcinogenic. This concept is based on a flawed assumption. NIR can and does cause cancer not by increasing the production of free radicals but by interfering with the repair mechanisms that neutralize free-radicals. While the mechanisms differ, the consequences of both NIR and IR are the same–oxidative stress resulting in cellular damage including cancer.

People are exposed to ELF radiation emitted by natural (e.g. sun, soil) or artificial sources (e.g. mobile phones, laptops). All of these electronic devices emit radio frequency radiation.

It is common knowledge that radiation has always been a natural part of the environment. [4] [5] [6] [7] Radiation is energy that comes from a specific source and is able to penetrate various materials. The sources of radiation are divided into two main categories: natural and man-made.

All living things on Earth are exposed to a background level of radiation from naturally occurring substances both on Earth and in space. For example, we can name terrestrial radiation (which can be found in soil) and cosmic radiation, from the Sun (and other sources).

Man-made radiation has been emitted for about 150 years since the inventions of the industrial revolution went into widespread use, now we’re part of the digital revolution. Artificial sources of radiation are claimed to be responsible for about 21% of the total exposure. An even higher level of exposure (50%) may affect industrialized countries due to the more widespread access to technology.[8]
