Radiofrequency radiation from nearby base stations gives high levels in an apartment in Stockholm, Sweden: A case report

We measured radiofrequency radiation in an apartment in Stockholm. The study is open under open access. Due to nearby bases stations high radiation levels were measure both in the apartment and on balconies.

A total of 74,531 measurements were made corresponding to ~83 h of recording. The total mean RF radiation level was 3,811 μW/m2 (range 15.2‑112,318 μW/m2) for the measurement of the whole apartment, including balconies. Particularly high levels were measured on three balconies and 3 of 4 bedrooms. The total mean RF radiation level decreased by 98% when the measured down‑links from the base stations for 2, 3 and 4 G were disre­garded. The results are discussed in relation to the detrimental health effects of non‑thermal RF radiation. Due to the current high RF radiation, the apartment is not suitable for long‑term living, particularly for children who may be more sensitive than adults. For a definitive conclusion regarding the effect of RF radiation from nearby base stations, one option would be to turn them off and repeat the measurements. However, the simplest and safest solution would be to turn them off and dismantle them.

Thus, we concluded that of special concern is the levels in bedrooms, especially those two used by children, since they seem to be more vulnerable to adverse health effects than grown‑ups. They have also a longer expected life in which illnesses may later become manifest. The results indicate that this apartment is unsuitable for long‑term living based on current knowledge of the potential adverse effects on health of RF radiation.

Another conclusion is that RF radiation should be measured in homes, especially before moving into a new one.


Fatal collision? Are wireless headsets a risk in treating patients?

In this recently published article wireless headsets are discussed. There is no open access to the article, but abstract is as follows:

Wireless-enabled headsets that connect to the internet can provide remote transcribing of patient examination notes. Audio and video can be captured and transmitted by wireless signals sent from the computer screen in the frame of the glasses. But using wireless glass-type devices can expose the user to a specific absorption rates (SAR) of 1.11–1.46 W/kg of radiofrequency radiation. That RF intensity is as high as or higher than RF emissions of some cell phones.  Prolonged use of cell phones used ipsilaterally at the head has been associated with statistically significant increased risk of glioma and acoustic neuroma. Using wireless glasses for extended periods to teach, to perform surgery, or conduct patient exams will expose the medical professional to similar RF exposures which may impair brain performance, cognition and judgment, concentration and attention and increase the risk for brain tumors. The quality of medical care may be compromised by extended use of wireless-embedded devices in health care settings. Both medical professionals and their patients should know the risks of such devices and have a choice about allowing their use during patient exams. Transmission of sensitive patient data over wireless networks may increase the risk of hacking and security breaches leading to losses of private patient medical and financial data that are strictly protected under HIPPA health information privacy laws.

A detailed discussion is made of such items as: What are wireless headsets and why are healthcare professionals being encouraged to use them? What is the problem for the medical professional? What is the problem for the patient? What’s the advice to medical professionals?

Case-control study on occupational exposure to extremely low-frequency electromagnetic fields and glioma risk

Exposure to extremely low-frequency electromagnetic fields (ELF-EMF) was in 2002 classified as a possible human carcinogen, Group 2B, by the International Agency for Research on Cancer (IARC) at WHO. In the international Interphone study on mobile phone use and glioma risk, glioma was associated with occupational ELF-EMF exposure in recent time windows. The authors concluded that such exposure may play a role in late stage carcinogenesis of glioma.

We assessed life time occupations in case-control studies during 1997-2003 and 2007-2009 on e.g. use of wireless phones and glioma risk. An ELF-EMF Job-Exposure Matrix was used for associating occupations with ELF exposure (μT). Cumulative exposure (μT-years), average exposure (μT), and maximum exposed job (μT) were calculated.

Cumulative exposure gave for astrocytoma grade IV (glioblastoma multiforme) in the time window 1-14 years before diagnosis odds ratio (OR) = 1.9, 95% confidence interval (CI) = 1.4-2.6, p linear trend <0.001, and in the time window 15+ years OR = 0.9, 95% CI = 0.6-1.3, p linear trend = 0.44 in the highest exposure categories 2.75+ and 6.59+ μT-years, respectively.

We concluded that we found an increased risk in late stage (promotion/progression) of astrocytoma grade IV for occupational ELF-EMF exposure. No statistically significant interaction was found between exposure to ELF-EMF and use of wireless phones (exposure to radiofrequency radiation; RF-EMF). They were independent risk factors for astrocytoma grade IV.

World Health Organization, radiofrequency radiation and health – a hard nut to crack (Review)

In a new article by Dr Lennart Hardell health effects from radiofrequency radiation, ICNIRP and the WHO agenda are discussed. The whole article can be found here, see also abstract below.

Abstract. In May 2011 the International Agency for Research on Cancer (IARC) evaluated cancer risks from radiofrequency (RF) radiation. Human epidemiological studies gave
evidence of increased risk for glioma and acoustic neuroma. RF radiation was classified as Group 2B, a possible human carcinogen. Further epidemiological, animal and mechanistic
studies have strengthened the association. In spite of this, in most countries little or nothing has been done to reduce exposure and educate people on health hazards from RF
radiation. On the contrary ambient levels have increased. In 2014 the WHO launched a draft of a Monograph on RF fields and health for public comments. It turned out that five
of the six members of the Core Group in charge of the draft are affiliated with International Commission on Non-Ionizing Radiation Protection (ICNIRP), an industry loyal NGO, and
thus have a serious conflict of interest. Just as by ICNIRP, evaluation of non-thermal biological effects from RF radiation are dismissed as scientific evidence of adverse health effects in the Monograph. This has provoked many comments sent to the WHO. However, at a meeting on March 3, 2017 at the WHO Geneva office it was stated that the WHO has no intention to change the Core Group.



Effects of Mobile Phones on Children’s and Adolescents’ Health: A Commentary

Effects of Mobile Phones on Children’s and Adolescents’ Health: A Commentary

Author: Lennart Hardell

In: Special Section of Child Development. Contemporary Mobile Technology and Child and Adolescent Development, edited by Zheng Yan and Lennart Hardell, May 15, 2017.


The use of digital technology has grown rapidly during the last couple of decades. During use, mobile phones and cordless phones emit radiofrequency (RF) radiation. No previous generation has been exposed during childhood and adolescence to this kind of radiation. The brain is the main target organ for RF emissions from the handheld wireless phone. An evaluation of the scientific evidence on the brain tumor risk was made in May 2011 by the International Agency for Research on Cancer at World Health Organization. The scientific panel reached the conclusion that RF radiation from devices that emit nonionizing RF radiation in the frequency range 30 kHz–300 GHz is a Group 2B, that is, a “possible” human carcinogen. With respect to health implications of digital (wireless) technologies, it is of importance that neurological diseases, physiological addiction, cognition, sleep, and behavioral problems are considered in addition to cancer. Well-being needs to be carefully evaluated as an effect of changed behavior in children and adolescents through their interactions with modern digital technologies.


In spite of the IARC evaluation little has happened to reduce exposure to RF fields in most countries. The exposure guideline used by many agencies was established in 1998 by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and was based on thermal (heating) effects from RF radiation neglecting non-thermal biological effects. It was updated in 2009 and still gives the guideline 2 to 10 W/m2 for RF radiation depending on frequency.

In contrast to ICNIRP the BioInitiative Report from 2007, updated in 2012, based the evaluation also on non-thermal health effects from RF radiation. The scientific benchmark for possible health risks was defined to be 30 to 60 µW/m2.  Thus, using the significantly higher guideline by ICNIRP gives a ‘green card’ to roll out the digital technology thereby not considering non-thermal health effects from RF radiation. Numerous health hazards are disregarded such as cancer, neurological diseases, psychological addiction, cognition, sleep and behavioral problems.

For obvious reasons the extent and severity of long-term health effects among children and adolescents using this technology are not know. However, there are already numerous peer-reviewed studies showing health hazards from wireless devices. Urgent action using the precautionary principle is needed.

Pentachlorophenol is a human carcinogen, Group 1

In October 2016 18 scientists met at IARC for evaluation of pentachlorophenol (PCP) as a human carcinogen. The panel classified PCP as ‘carcinogenic to humans’ Group 1. PCP is a persistent organic pollutant under the Stockholm Convention. Chlorophenols, mostly PCP, have been used as wood preservatives. The use was banned in Sweden in 1978 with few exceptions. Wood impregnated with PCP may still entail a health hazard. In case-control studies we associated use of chlorophenols, as well as phenoxy herbicides, with increased risk for soft-tissue sarcoma (1979) and malignant lymphoma, both Hodgkin’s disease and non-Hodgkin lymphoma (1981). These results were the first studies in the world showing a carcinogenic potential of these agents, and further discussed in an article published in 1982.

Our results associated exposure to chlorophenols and the weed-killers phenoxy herbicides, with contaminating TCDD, with increased risk for soft-tissue sarcoma and malignant lymphoma. The results were soon questioned by industry and its allied experts including scientists with their own hidden agenda, even with funds from the Swedish Cancer Society aimed at preventing cancer, see


The lesson is that it took 37 years from the first publication showing PCP as a human carcinogen to establish causation, years that were lost for cancer prevention.

New study confirms increased risk for glioma associated with use of mobile phones and cordless phones

We published recently a pooled analysis of our case-control studies on glioma and use of mobile phones and cordless phones. The study has been published in Pathophysiology after pre-review and can be accessed via Internet. The results confirm a statistically significant increased risk for glioma and the risk increases with time from first use of the wireless phone and number of hours for use over the years. The risk is highest on the same side of the brain as the phone has been used, especially in the area with the highest exposure to microwaves, the temporal lobe, which would be expected.

These studies strengthen the 2011 classification by IARC at WHO that the microwave exposure is a ‘Possible human carcinogen’, Group 2B. In fact using the Hill viewpoints on association and causation it should be classified as Group 1, the agent causes human cancer. We have explored that fact in more detail in a previous article. The present results confirm that classification.

Our results have gained interest in many countries after a press release by Reuters and have also been discussed in the Finnish Medical newspaper. However, these worrying results for human health have not been discussed at all in Sweden, so the layman is uniformed about how important it is to avoid such exposure.
