Lennart Hardell MD, Ph.D.,
Oncology, Cancer epidemiology
Clinical and Research Physician
The Environment and Cancer Research Foundation, Sweden

Dr. Hardell has worked as a specialist oncologist and a cancer epidemiologist since the 1970’s. He has a background at the Department of Oncology, Örebro University Hospital, Sweden, as well as previously at the Department of Oncology, Umeå University Hospital.

After his retirement from the Örebro University Hospital, his research is performed at The Environment and Cancer Research Foundation, Örebro, Sweden.  (

Dr. Hardell has a long career as a clinical and medical research doctor. His main interest has been epidemiological studies on environmental risk factors for cancer. He was a Research Fellow at the School of Public Health, University of California, Berkeley, USA in 1984-1985. He has published more than 400 peer-reviewed scientific articles.

Over the years Dr. Hardell has been awarded several scientific awards for his research. In the late 1970’s and early 1980’s he was the first to show an increased risk for cancer in persons exposed to phenoxy herbicides and contaminating dioxins, used in products such as Hormoslyr and Agent Orange. He and his co-workers have also studied cancer risks associated with exposure to the herbicide glyphosate (Roundup). Exposure to persistent organic pollutants and cancer risks, such as PCB and the risk for e.g., malignant lymphoma has been a main topic for previous research. He was one of 30 international experts invited to the IARC in 2011 to evaluate cancer risks from radiofrequency radiation emitted from wireless technologies.

In recent years much of Dr. Hardell’s research has focused on the use of mobile phones, cordless phones and the risk of brain tumours, as well as other health risks associated with exposure to radiation from wireless technologies. His research has contributed to the cancer classification of different agents such as TCDD, PCB, and the herbicide glyphosate.

This list presents selected peer-reviewed articles on health risks associated with exposure to ionizing and non-ionizing (radiofrequency) radiation.
