The document discusses potential health effects of electromagnetic fields (EMFs) from cell phones and other sources. It summarizes that EMFs can cause both thermal effects, by heating tissues, and non-thermal (athermal) effects, through interactions at the molecular level. Thermal effects are minimized in cell phones due to limits on power output. Potential health impacts of EMFs discussed include effects on biological membranes, cell growth and proliferation, and increased risk of tumors and cancer. The document provides an overview of EMF sources and exposure levels in India.
