Using a cell phone handset could cause adverse health effects in neurobehavioral function. - GreenMedInfo Summary

In order to study the effects of electromagnetic radiation from handsets of cellular telephone on neurobehavioral function, 81 staff with handsets of cellular telephone and 63 staff without handsets of cellular telephone from corporations were selected as the subjects. The subjects were investigated by questionnaire on their general health, lifestyle habit, suppress of spirit, handset using of cellular telephone, environmental exposure, morbidity, and the neurobehavioral core test battery(NCTB). The data was analyzed by chi-square, stepwise regression analysis and covariance statistics. The results showed that the average reaction time in user's group was longer than that in control group (P<0.01). The time of using handset was negatively associated with corrected reaction number (P<0.01). The fast reaction time and the slowest reaction time were positively associated with the length of handset using (P<0.01, P<0.05). The results suggested that the handset using could cause adverse health effects in neurobehavioral function.
