Abstract

When theory and observation collide: Can non-ionizing radiation cause cancer? Havas, M. When theory and observation collide: Can non-ionizing radiation cause cancer? Environmental Pollution (2016). dx.doi.org Highlights • There is sufficient scientific evidence of cellular damage caused by non-ionizing radiation well below thermal guidelines. • Applying the ionization model to non-ionizing radiation is inappropriate as mechanisms of biological interactions differ. • Free radicals can and do cause cancer and non-ionizing radiation can and does increase free-radicals. Abstract This paper attempts to resolve the debate about whether non-ionizing radiation (NIR) can cause cancer-a debate that has been ongoing for decades. The rationale, put forward mostly by physicists and accepted by many health agencies, is that, "since NIR does not have enough energy to dislodge electrons, it is unable to cause cancer." This argument is based on a flawed assumption and uses the model of ionizing radiation (IR) to explain NIR, which is inappropriate. Evidence of free-radical damage has been repeatedly documented among humans, animals, plants and microorganisms for both extremely low frequency (ELF) electromagnetic fields (EMF) and for radio frequency (RF) radiation, neither of which is ionizing. While IR directly damages DNA, NIR interferes with the oxidative repair mechanisms resulting in oxidative stress, damage to cellular components including DNA, and damage to cellular processes leading to cancer. Furthermore, free radical damage explains the increased cancer risks associated with mobile phone use, occupational exposure to NIR (ELF EMF and RFR), and residential exposure to power lines and RF transmitters including mobile phones, cell phone base stations, broadcast antennas, and radar installations. Summary This paper presents a highly probable mechanism that involves an increase in free-radicals, which-in turn- explains the increased risk of cancers documented in epidemiological studies that are associated with environmental exposure to RFR and ELF-EMFs at levels well below international guidelines.

Main findings

The paper argues that non-ionizing radiation (ELF EMF and RF radiation) can increase free radicals and oxidative stress, interfering with oxidative repair mechanisms and causing cellular damage including DNA damage, which could lead to cancer. It states that this mechanism could explain increased cancer risks reported in epidemiological studies for exposures (e.g., mobile phone use, occupational exposure, and residential proximity to power lines and RF transmitters) at levels below international guidelines.
