The effects of a chronic exposure of mice to a 50 Hz magnetic field on the incidence of cancer, organ weights and male fertility should be investigated.
The offspring of 10 pregnant mice, which were exposed to the magnetic field during their last week of pregnancy until birth, were used as the exposure group (n=66). The offspring was further exposed after birth for 15.5 months. The offspring of 10 pregnant mice without exposure used for control group (n=62).
ばく露時間: continuous for 12 hours per day for 1 week before birth (in utero) and 15.5 months after birth

The body weight and weight of the liver of exposed animals were significantly decreased compared to the control group.
In exposed animals, the incidence of chronic myeloid leukemia was significantly greater compared to the control group.
The seminiferous tubules diameter was significantly reduced in exposed animals in comparison to the control group.
The authors conclude that a chronic exposure of mice to a 50 Hz magnetic field might increase the incidence of chronic myeloid leukemia and could have a detrimental effect on the male fertility.
