Jan 1, 2016
This animal study examined whole-body RF-EMF exposure (900 or 1800 MHz) for 2 hours/day over 90 days in growing male rats, compared with sham controls. Exposed rats showed greater weight and length increases and higher levels of several hormones and calcium. The study also reports changes in femoral growth plate…
Effects of extremely low-frequency electromagnetic fields (ELF-EMF) exposure on B6C3F1 mice

May 5, 2015
This long-term animal study exposed mice to a 50 Hz magnetic field (500 mG) prenatally and then through 15.5 months of life to assess tumor-related outcomes and fertility-related measures. Exposed mice had lower body weights and showed no increase in liver or lung tumor incidence. However, exposed female mice had a…
Correlates of mobile phone use in HIV care: Results from a cross-sectional study in South Africa.
Research
RF Safe Research Library
Jan 1, 2015
This cross-sectional study surveyed 883 HIV-infected patients on ART in Soweto, South Africa, to identify demographic correlates of using mobile phones as reminder tools. Older age, female gender, and lower education were associated with lower use of phones for clinic appointment reminders. Older age and lower income…
Prevalence and correlates of cell phone use among Texas drivers.
Research
RF Safe Research Library
Jan 1, 2015
This observational study measured the prevalence of cell phone use among 1,280 drivers in six Texas cities from 2011–2013. Any cell phone use while driving was observed in 18.7% of drivers, with talking tending to decline and texting seeming to increase over time. Use was more common among female drivers, drivers…
Assessment and comparison of total RF-EMF exposure in femtocell and macrocell base station scenarios.
Research
RF Safe Research Library
Jan 1, 2014
This study assessed and compared total RF-EMF exposure for a mobile-phone user in an office environment when connected to an indoor femtocell base station versus a conventional macrocell base station. Using a framework that combines near-field and far-field exposure, the authors report a 20–40× reduction in total…
Electromagnetic Radiofrequency Radiation Emitted from GSM Mobile Phones Decreases the Accuracy of Home Blood Glucose Monitors.
Research
RF Safe Research Library
Jan 1, 2014
This study tested whether radiofrequency emissions from a ringing GSM mobile phone affect home blood glucose monitor readings. Among 45 female nondiabetic students, the group measured in the presence vs absence of a ringing phone showed larger changes between two readings than a repeat-measurement control group…
Epidemiological characteristics of mobile phone ownership and use in korean children and adolescents.
Research

Jan 1, 2013
This cross-sectional analysis used three Korean databases (2008–2011; n=21,693) to describe mobile phone ownership and use among children and adolescents and how these patterns vary by socioeconomic position. Ownership and use were higher among females, older students, and in 2011 compared with 2008, and the age of…

Jan 1, 2012
This study assessed whether mobile phone radiofrequency exposure during a 40-second ringing period alters ECG parameters in 356 participants across cardiac disease groups, with gender stratification. The authors report QTc prolongation in males across groups, including males with ischemic heart disease, and…
Effects of radiofrequency radiation exposure on blood-brain barrier permeability in male and female rats
Research

Jan 1, 2011
This rat study tested whether acute exposure to 0.9 and 1.8 GHz continuous-wave radiofrequency radiation alters blood-brain barrier permeability. Using Evans-blue/albumin as a tracer, the authors report no BBB leakage in exposed female rats but a significant increase in albumin in exposed male rat brains versus sham.…
