Jan 1, 2014
This field experiment examined short-term (48-hour) exposure to RF EMF from a GSM 900 MHz mobile phone base station on reproductive endpoints in four invertebrate species. The study reports no significant effects of exposure metrics on fecundity or number of offspring, and notes that distance was not a suitable proxy…
Exposure Knowledge and Risk Perception of RF EMF.
Research
RF Safe Research Library
Jan 1, 2014
This cross-sectional survey study (LEXNET project) examined how subjective exposure knowledge relates to risk perception (RP) for different RF EMF sources. Respondents were more concerned about base stations than other sources. Regression results suggested that most exposure-characteristic features (except distance)…
