Biotechnology
- the majority of the radiofrequency energy emitted by a cell phone is absorbed by the hand & head of the user[5]
- brain glucose metabolism, assessed by PET is increased in the region of the brain closest to the activated cell phone's antenna
- whole-brain glucose metabolism is not affected by cell phone use
- significance unknown
Adverse effects
- associated with increased risk of motor vehicle accident[1]
- 4-fold increase risk within 10 minutes of use
- risk not affected by sex, age, or type of mobile phone used
- both hand-held & hands-free phones associated with increased risk
- cell phone use may decrease sperm quality[3] as assessed by sperm count, motility, viability, morphology
- increased risk of brain tumors ?
- association of cell phone use with brain tumors[6][7]
- possibly increased risk of glioma[8]
- cell phone use not linked to brain tumors[9]
- exposure to radiofrequency fields from cell phone use does not likely increase risk of brain cancer[13]
- parental distraction with cell phone use may increase levels of anxiety in adolescents & predispose them to ADHD[12]
Comparative biology
- report of increased cancer risk in male Sprague-Dawley rats exposed to radiofrequency cell phone radiation[10]
- incidence of malignant schwannomas of heart increased with increasing radiofrequency radiation exposure in male rats, at levels beyond that allowed by cell phones [11]
- no association between radiofrequency radiation exposure & malignant schwannomas in female rats or in mice of either sex[11]
- equivocal findings of increased neoplasms of brain, prostate, liver, & pancreas in both rats & mice[11]
- radiofrequency radiation exposure associated with ventricular cardiomyopathy in rats but not mice[11]
