Does mobile phone use of women during pregnancy cause hearing problems in infants? Preliminary observation

Objective Some studies have claimed that long-term conversation with mobile phones can cause hearing loss. However, it has not been investigated whether exposure to mobile phones during pregnancy affects the hearing of babies in the womb. Therefore, the aim of this human study was to investigate the effects of intrauterine radiofrequency radiation (RFR) exposure emitted from mobile phones on the hearing of newborns. Methods The study population comprised 149 newborns. Pregnant women in this study were divided into 4 groups according to RFR exposure duration, such as non-exposure to RFR, exposure to RFR for 2–15 min/day, exposure to RFR for 15–60 min/day, and exposure to RFR for more than 60 min/day. The results of the hearing screening analyses of the newborns, which were performed using transiently evoked otoacoustic emission and auto auditory brainstem response, were investigated retrospectively. Results The results of this study indicated that 900 and 1800 MHz RFR exposure during pregnancy did not cause hearing loss in newborns. Conclusion In conclusion, we observed that the hearing sensitivity and peripheral sound perception of newborns were not affected by RFR exposure emitted from mobile phones during the intrauterine period. Further studies should be performed to illuminate the subject

Ionizing radiations and cancer

The aim of this study is to evaluate the biologic effects of ionizing radiation and relation between medical diagnosticradiation exposure and cancer risk. Many unnecessary ionizing radiation applications are performed in the medicalcenters and hospitals. Therefore the health staff and the patients expose to serious risks of radiation. On the other hand, recently some studies, which suggested relationshipsbetween low dose ionizing radiation and some cancers, have been published. The relationship between low dose ionizing radiation and cancer can be more understandablewhen the stochastic effects of ionizing radiationtake into consideration. This presented review calls attention to the fact that low dose ionizing radiation may be an important factor for increased cancer risk. Therefore,physicians, health workers and patients have to pay maximum attention to avoid hazards of low dose ionizing radiation

Exposure to non-ionizing electromagnetic fields emitted from mobile phones induced DNA damage in human ear canal hair follicle cells

The aim of this study was to investigate effect of radiofrequency radiation (RFR) emitted from mobile phones on DNA damage in follicle cells of hair in the ear canal. The study was carried out on 56 men (age range: 30-60years old)in four treatment groups with n=14 in each group. The groups were defined as follows: people who did not use a mobile phone (Control), people use mobile phones for 0-30min/day (second group), people use mobile phones for 30-60min/day (third group) and people use mobile phones for more than 60min/day (fourth group). Ear canal hair follicle cells taken from the subjects were analyzed by the Comet Assay to determine DNA damages. The Comet Assay parameters measured were head length, tail length, comet length, percentage of head DNA, tail DNA percentage, tail moment, and Olive tail moment. Results of the study showed that DNA damage indicators were higher in the RFR exposure groups than in the control subjects. In addition, DNA damage increased with the daily duration of exposure. In conclusion, RFR emitted from mobile phones has a potential to produce DNA damage in follicle cells of hair in the ear canal. Therefore, mobile phone users have to pay more attention when using wireless phones
