Effects of Randomly Varied Power Frequency Magnetic Fields on the Life-Expectancy of Two Strains of Mice

Research shows that exposure to electromagnetic fields can cause biological effects such as circadian rhythm shifts and stress.1,2. Furthermore, epidemiological studies suggest that extremely low frequency electromagnetic fields might play a role in the development of leukaemia 3. Thus, although exposure to these fields might not lead to direct adverse health effects, the question arises whether long -term exposure might not eventually affect life-expectancy. In a previous study 4 we reported on a shortened life-expectancy in BALB/c mice after long-term exposure to an electric field of 10 KV/m.
