Speaking of research references another great source is the EMF-Portal in Germany:
The internet information platform EMF-Portal of the RWTH Aachen University summarizes systematically scientific research data on the effects of electromagnetic fields (EMF). Interested citizens, decision makers and opinion leaders, such as doctors, lawyers and politicians, can find all the information in both English and German. The EMF-Portal consists of various modules (including a literature database, a glossary and a database of field sources), which are related and linked to each other. The core of the EMF-Portal is an extensive literature database of individual scientific studies on the effects of electromagnetic fields. In systematic searches, new articles are researched and added to this collection daily.
