Qi-Shield & wound healing

31 December 2019

Studie vom Dartsch-Institut zu Qi-Shield, WLAN und Wundheilung

The study examined the effect of non-thermal radiation emitted by an active mobile phone on cell regeneration/wound healing in cultured cells. In addition, it also investigated if there is a protective effect of a Qi- Shield on cells exposed to mobile phone radiation.

The study results showed that cell regeneration and wound healing was strongly reduced by the non-thermal radiation of an active mobile phone, and that the use of the Qi-Shield neutralised this effect by approximately 90%.

Qi-Home Cell & water quality

10 July 2019

Dartsch Institute, graphic Qi water and untreated tap water

Dartsch Scientific investigated whetherwater exposed to the Qi-Home Cell(“Qi water”) has any potentially beneficial effect on cells, in comparison with untreated tap.

The results of the experiment showed thatQi water had an antioxidative effect against both exogenous (external) and endogenous (internal) free oxygen radicals, such inflammatory processes in the body.

Qi-Shield & protective influence on human organism against wirleless router radiation

9 August 2019

Studie vom Bion-Institut zu Qi-Shield und Schutzwirkung für den Menschen gegenüber WLAN-Strahlung

This study examined what happens to humans when exposed to a wifi router in vicinity, and in the presence of a Qi-Shield device. Electrophysiological parameters of 45 subjects were tested in total, divided into three groups (real Qi-Shield + wifi on, sham Qi-Shield + wifi on, and a control group).

The results of the study showed that the Qi-Shield promoted relaxation and had a protective influence on the body against wireless router radiation.

General Studies

High frequency radiation & electrosensitivity

FCC & Qi-Shield
1. Electromagnetic hypersensitivity − an increasing challenge to the medical profession

Hedendahl L, Carlberg M, Hardell L.

Published in: Rev Environ Health. 2015;30(4):209-15. doi: 10.1515/reveh-2015-0012.

Authors reviewed the literature on different aspects of EHS and potential adverse health effects of RF-EMF, as well as case reports. Most people are unaware of this type of exposure, which has no smell, color, or visibility. There is an increasing concern that wireless use of laptops and iPads in Swedish schools, where some have even abandoned textbooks, will exacerbate the exposure to EMF.


2. Appeals that matter or not on a moratorium on the deployment of the fifth generation, 5G, for microwave radiation

Hardell L, Nyberg R. Mol Clin Oncol. 2020 Mar;12(3):247-257. doi: 10.3892/mco.2020.1984. Epub 2020 Jan 22.

In this article, the warnings on the health risks associated with RF presented in the 5G appeal and the letters to the EU Health Commissioner since September, 2017 and the authors’ rebuttals are summarized. The responses from the EU seem to have thus far prioritized industry profits to the detriment of human health and the environment.


3. High ambient radiofrequency radiation in Stockholm city, Sweden

Carlberg M, Hedendahl L, Koppel T, Hardell L. Oncol Lett. 2019 Feb;17(2):1777-1783. doi: 10.3892/ol.2018.9789. Epub 2018 Dec 3.

The authors measured the radiofrequency (RF) radiation at central parts in Stockholm, Sweden in March and April 2017.


4. Comments on the US National Toxicology Program technical reports on toxicology and carcinogenesis study in rats exposed to whole-body radiofrequency radiation at 900 MHz and in mice exposed to whole-body radiofrequency radiation at 1,900 MHz

Hardell L, Carlberg M. Int J Oncol. 2019 Jan;54(1):111-127. doi: 10.3892/ijo.2018.4606. Epub 2018 Oct 24.

The main aim of this study was to compare earlier human epidemiological studies with US National Toxicology Program (NTP) findings, including a short review of animal studies. The authors conclude that there is clear evidence that RF radiation is a human carcinogen, causing glioma and vestibular schwannoma (acoustic neuroma). There is some evidence of an increased risk of developing thyroid cancer, and clear evidence that RF radiation is a multi‑site carcinogen. Based on the Preamble to the IARC Monographs, RF radiation should be classified as carcinogenic to humans, Group 1.


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

Hardell L, Carlberg M, Hedendahl LK. Oncol Lett. 2018 May;15(5):7871-7883. doi: 10.3892/ol.2018.8285. Epub 2018 Mar 16.

In the present study, the levels of RF radiation were measured in an apartment close to two groups of mobile phone base stations on the roof. 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.


6. Measurements of Radiofrequency Radiation with a Body-Borne Exposimeter in Swedish Schools with Wi-Fi

Hedendahl LK, Carlberg M, Koppel T, Hardell L. Front Public Health. 2017 Nov 20;5:279. doi: 10.3389/fpubh.2017.00279. eCollection 2017.

This study conducted exposi metric measurements in seven schools to assess RF emissions in the classroom by measuring the teachers’ RF exposure in order to approximate the children’s exposure.


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

Hardell L. Int J Oncol. 2017 Aug;51(2):405-413. doi: 10.3892/ijo.2017.4046. Epub 2017 Jun 21. Review.

In the article the authors discuss the following: 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.


8. High radiofrequency radiation at Stockholm Old Town: An exposimeter study including the Royal Castle, Supreme Court, three major squares and the Swedish Parliament

Hardell L, Carlberg M, Koppel T, Hedendahl L. Mol Clin Oncol. 2017 Apr;6(4):462-476. doi: 10.3892/mco.2017.1180. Epub 2017 Mar 3.

Outdoor RF radiation level was measured during five tours in Stockholm Old Town in April, 2016.


9. Evaluation of Mobile Phone and Cordless Phone Use and Glioma Risk Using the Bradford Hill Viewpoints from 1965 on Association or Causation

Carlberg M, Hardell L. Biomed Res Int. 2017;2017:9218486. doi: 10.1155/2017/9218486. Epub 2017 Mar 16. Review.

Bradford Hill’s viewpoints from 1965 on association or causation were used on glioma risk and use of mobile or cordless phones. All nine viewpoints were evaluated based on epidemiology and laboratory studies.


10. Where’s Your Phone? A Survey of Where Women Aged 15-40 Carry Their Smartphone and Related Risk Perception: A Survey and Pilot Study

Redmayne M. PLoS One. 2017 Jan 6;12(1):e0167996. doi: 10.1371/journal.pone.0167996. eCollection 2017.

This survey used an online questionnaire to ask about smartphone location under several circumstances to inform the power calculation for a women’s health study. They were also asked about risk perceptions.


11. Radiofrequency radiation at Stockholm Central Railway Station in Sweden and some medical aspects on public exposure to RF fields

Hardell L, Koppel T, Carlberg M, Ahonen M, Hedendahl L. Int J Oncol. 2016 Oct;49(4):1315-1324. doi: 10.3892/ijo.2016.3657. Epub 2016 Aug 12.

The Stockholm Central Railway Station in Sweden was investigated for public radiofrequency (RF) radiation exposure.
