Mesothelioma is most commonly associated with asbestos due to the large number of cases that support this connection. However, there are other sources that can be linked to this deadly disease. In fact, ionizing radiation has also been identified as a cancer-causing agent that has been a precursor to mesothelioma diagnoses, albeit extremely rare.

Cancer has many causes and risk factors.

When discussing radiation, it is commonly understood thasst ionizing radiation is a potential cause of cancer. However, the non-ionizing version, found in microwaves and infrared radiation, has generally not been considered a carcinogen. This is an important distinction that might easily be missed.

Numerous studies have supported the broad scientific consensus that everyday devices like cell phones and microwaves, which emit non-ionizing radiation, are safe for use, although they pose some risk. For instance, the heat generated by infrared radiation or microwaves can cause burns or raise body temperature.

In this article, we will take an even closer look at non-ionization and suspicions that it is connected to certain cancers, specifically mesothelioma. Is the connection really a concern, is this a myth, or is it still too soon to tell?

What is Non-Ionizing Radiation?

Non-ionizing radiation is a type of energy released by a wide range of sources, both natural and man-made. It is found to the left of ionizing radiation on the electromagnetic spectrum. Examples of such radiation include:

·        Radiofrequency (RF) radiation used in many broadcast and communications applications,

·        Home and office microwaves,

·        Infrared radiation used in heat lamps, and

·        Ultraviolet (UV) radiation from the sun and tanning beds.

Unlike ionizing radiation, the non-ionizing kind lacks sufficient energy to kick out any electrons from atoms and molecules. However, it can cause atoms to vibrate, which can lead to them heating up. This is precisely how a microwave works – it heats water molecules within the food – not the food itself. And the heating capability of non-ionizing radiation is what many are now considering to be a health risk.

Non-Ionizing Radiation & Cancer

The relationship between non-ionizing radiation and cancer has been the subject of extensive research. The National Cancer Institute states that there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans. Similarly, researchers at the University of Pennsylvania suggest, via studies, they have not been able to find any conclusive evidence that can suggest that there is any link between a person being exposed to non-ionizing radiation and the development of cancer.

However, other studies suggest that non-ionizing radiation can damage cells and DNA, creating a perfect playground for cancerous growths to appear in the body. These studies are to date not yet widely accepted in the scientific community due to the need for further research and validation.

According to the World Health Organization (WHO), the primary mechanism through which non-ionizing radiation interacts with biological tissue is through heat generation. However, at the same time, WHO also suggests that exposure to low levels of non-ionizing radiation is a common occurrence and does not typically cause a problem.

The Need for Further Research

While the current body of research suggests that non-ionizing radiation is unlikely to be a significant factor in cancer development, the field is still active, and new research could potentially change our understanding. 

For example, ongoing investigations are examining the long-term effects of exposure to non-ionizing radiation from sources like cell phones. Thus far, it has been proven that non-ionizing radiation can cause physical effects such as heat, yet its role in cancer development is not well-established.

Non-Ionizing Radiation and Mesothelioma

When it comes to mesothelioma, a rare form of cancer most commonly associated with asbestos exposure, the connection with non-ionizing radiation is even less clear. A few published reports have suggested that mesotheliomas developed after people were exposed to high doses of radiation to the chest or abdomen as treatment for another cancer. However, these cases are extremely rare and the risk of mesothelioma is still higher in patients who have been exposed to ionizing radiation.

While there are reports that exist, the link that they make between non-ionizing radiation and mesothelioma has not been confirmed. Most studies focus on the other kind, which is known to cause damage to DNA and other cellular structures. 

Scientific Study Review


An exhaustive review of scientific literature and a meta-analysis conducted by Visci et al. thoroughly investigated the correlation between ionizing radiation exposure and the risk of developing mesothelioma. The findings indicated that exposure to ionizing radiation could potentially serve as a risk factor for mesothelioma, encompassing both instances of high-dose, short-term exposure (EBRT) and low-dose, prolonged exposure (occupational exposure).

Similarly, an additional study featured in the American Journal of Public Health delved into the connection between radiation and the increased occurrence of mesothelioma-related deaths among deceased nuclear workers affiliated with the US Transuranium and Uranium Registries. The study disclosed a proportionate mortality ratio (PMR) of 62.40 and a proportionate cancer mortality ratio (PCMR) of 46.92 specifically for mesothelioma.

These findings highlight that while there have been isolated instances linking mesothelioma to radiation exposure, such cases are exceptionally rare, and the association between non-ionizing radiation and mesothelioma lacks sufficient validity. A more in-depth exploration is necessary to comprehensively grasp the potential risks associated with non-ionizing radiation and disease development.

Regulatory Guidelines and Safety Standards for Non-Ionizing Radiation

Non-ionizing radiation is regulated by several international and national bodies to ensure the safety of individuals and the environment. These bodies have established guidelines and safety standards based on extensive scientific research.

International Commission on Non-Ionizing Radiation Protection (ICNIRP)

The ICNIRP is an independent organization that provides scientific advice and guidance for health hazards associated with non-ionizing radiation. It has established guidelines for ensuring the exposure to electromagnetic fields is limited.  The agency’s guidelines are designed to protect humans from potential health hazards associated with exposure.

Occupational Safety and Health Administration (OSHA)

In the United States, OSHA provides regulations and guidelines for occupational exposure to non-ionizing radiation. The agency provides standards and regulations for different types of non-ionizing radiation, including:

·        Radiofrequency

·        Microwave radiation,

·        Infrared radiation,

·        Visible light radiation,

·        Ultraviolet radiation, and

·        Laser hazards.

National Institute for Occupational Safety and Health (NIOSH)

NIOSH also provides resources and guidelines for protecting workers from non-ionizing radiation hazards, focusing primarily on electric and magnetic fields (EMF) and providing resources for understanding and controlling these hazards.

Other Regulatory Bodies

In addition to these organizations, there are other national and international bodies that regulate non-ionizing radiation. These include the WHO (mentioned above), the European Union (EU) and others.

The regulatory guidelines and safety standards for non-ionizing radiation are based on extensive scientific research and are regularly updated to reflect the latest scientific understanding. Staying up to date with established protocols can be a useful tool when it comes to mesothelioma claims.

Public Perception and Misconceptions Regarding Non-Ionizing Radiation

In recent years, there has been a growing public concern surrounding the safety of devices emitting non-ionizing radiation, such as phones, Wi-Fi routers, and microwave ovens. Despite extensive scientific research and regulatory guidelines, misconceptions and myths persist regarding the potential health risks associated with non-ionizing radiation exposure. One common misconception is that non-ionizing radiation emitted by everyday electronic devices will eventually cause cancer if a person is exposed long enough. This belief originates from a misconception regarding the disparities between ionizing and non-ionizing radiation.

Despite the lack of conclusive evidence linking non-ionizing radiation to adverse health effects, public perception remains influenced by sensationalized media reports and anecdotal accounts. The proliferation of misinformation on social media platforms further exacerbates public concerns and contributes to the perpetuation of myths surrounding non-ionizing radiation.

To address these misconceptions and provide evidence-based insights, it is essential to emphasize the following points:

  1. Scientific Consensus

The overwhelming majority of scientific studies and regulatory agencies, including the WHO and the International Commission on Non-Ionizing Radiation Protection (ICNIRP), have concluded that devices emitting non-ionizing radiation pose no significant health risks when used according to established guidelines.

  1. Regulatory Oversight: 

National and international regulatory bodies, such as the Federal Communications Commission (FCC) in the United States and the European Union (EU), have established safety standards and exposure limits for non-ionizing radiation. These guidelines are based on extensive research and are regularly monitored for any needed updates.

  1. Risk Communication:

It is important to communicate risk in a clear and transparent manner, acknowledging uncertainties while providing reassurance based on scientific evidence. Educating the public about the principles of radiation physics and the distinction between ionizing and non-ionizing radiation can help dispel misconceptions and alleviate concerns.

  1. Precautionary Measures

While the scientific consensus supports the safety of devices emitting non-ionizing radiation, individuals may choose to take precautionary measures to minimize exposure, such as using hands-free devices for phone calls and maintaining a safe distance from other household items when they’re in use.

In Closing… Non-ionizing radiation does not appear to cause cancer, but asbestos unmistakably does. 

Asbestos even makes lung cancer more likely in smokers. It also damages DNA and creates free radicals, increasing the risk of respiratory and digestive cancer.

Addressing public perception and misconceptions surrounding the safety of devices emitting non-ionizing radiation promotes informed decision-making and understanding of the science behind electromagnetic fields. This form of technology has revolutionized the world and has set us on the path toward the current information age. If used properly and without the fear of cancers or mesothelioma, we have the potential to expand upon the field further and continue evolving further.

Asbestos exposure continues to be the primary cause of mesothelioma, particularly among individuals who have worked in industries such as construction, shipbuilding, and manufacturing where the mineral was commonly used.

Latency: People exposed to asbestos in their youth may develop cancer as adults.

The latency period for mesothelioma can range from 20 to 60 years, meaning that individuals may not exhibit symptoms or receive a diagnosis until decades after exposure. Therefore, early detection through regular screening becomes imperative, especially for those with a history of asbestos exposure.

Screening for mesothelioma typically involves imaging tests such as chest X-rays, CT scans, and MRIs, as well as biopsy procedures to confirm the diagnosis. Early detection through screening can significantly improve treatment outcomes and increase the likelihood of successful intervention. Moreover, screening for mesothelioma is relatively straightforward and non-invasive, making it accessible to individuals at risk.
