She has served as Director of the Cancer and Radiation Epidemiology Unit at the Gertner Institute since 2000, and since 2001 serves as Principal Investigator of the Baruch Modan National Institute for 'Tinea Capitis' (scalp ringworm) research.  In 2009 she was appointed Associate Professor in the Department of Epidemiology and Preventive Medicine at the Sackler Faculty of Medicine, Tel Aviv University.  She has published more than 100 articles in the scientific literature and three chapters in textbooks.  Prof. Sadetzki is actively engaged in research on cancer and on ionizing and non-ionizing radiation.  She is involved in a number of studies examining the environmental and genetic causes of brain tumors.

Prof. Sadetzki is considered a national and international expert on non-ionizing radiation, and has served as principal investigator in the Israeli branch of a number of studies that examined the possible connection between exposure to mobile phones and other radiation-emitting devices, and the development of brain tumors in adults (the INTERPHONE study), and in children and adolescents (the MOBIKIDS study).  These international studies, (as well as the GERoNiMo Study, that examines a range of aspects of potential health risks arising from the use of wireless communication), are funded by the European Union.

Prof. Sadetzki has vast experience in policy making regarding health in general and non-ionizing radiation in particular, and for the past 15 years has served as consultant to the Ministry of Health and other policy-making bodies engaged in this field.  Among her activities, the following should be mentioned:  consolidation of the content of the 'precautionary principle' in Israel and its application to health; elaborating recommendations  for the Ministry of Health on the use of mobile and cordless phones; reviewing the effects of exposure to non-ionizing radiation in the environment of school children (including exposure to the electricity grid, mobile phones and wireless communication networks – Wi-Fi) and counselling the Ministry of Education on the protection school children; initiation of an intervention program regarding the educated use of mobile phones in the school children's environments (in collaboration with the Ministry of Education); counselling in determining the standards for electromagnetic radiation in the electricity grid, and the position regarding the introduction of '4th Generation' phones in Israel.

Prof. Sadetzki possesses wide international expertise in this field, and she represents the Ministry of Health on the World Health Organization's Advisory Committee on the subject of electromagnetic fields (EMF).  She has been invited to express an expert opinion before the American Congress at a hearing on non-ionizing radiation (2009), and before the US Government Accountability Office – GAO.
