Some studies [Lowenthal et al. 2007; Infante-Rivard and Deadman, 2003] report that the fetus and young children are at greater risk than are adults from exposure to environmental toxins. This is consistent with a large body of information showing that the fetus and young child are more vulnerable than older persons are to chemicals [Makri A, et al. 2004] and ionizing radiation [Preston, 2004]. These considerations have led the US Environmental Protection Agency (EPA) to propose a 10-fold risk adjustment for the first 2 years of life exposure to carcinogens, and a 3-fold adjustment for years 3 to 5 [http://www.epa.gov/sab/pdf/sab_04003_resp.pdf].
This susceptibility may be why, according to some authors (60) [Carpenter and Sage, 2008], "the evidence for the relation between magnetic field exposure and leukemia in children is stronger than that for adults".
