Effects of extremely low-frequency magnetic field exposure on cognitive functions: results of a meta-analysis.

abstract：:The aim of this study was to explore the prevalence, nature and determinants of concerns about mobile phone radiation. We used data from a 2006 telephone survey of 1004 people aged 15+ years in Denmark. Twenty-eight percent of the respondents were concerned about exposure to mobile phone radiation; radiation from mast...
