The result of a previous study (see publication 12091) that the exposure to 50 Hz magnetic field significantly protects against UV-induced embryo death should be further investigated concerning:
1) magnetic flux density dependency,
2) exposure time and
3) genetic dependency.
|Exposure duration||10, 20 or 60 min|
|Setup||two pairs of Helmholtz coils; the horizontal pair with a diameter of 40 cm, the vertical one with a diameter of 42 cm; all coils with three seperate 30 turn windings of which two were used; the two windings were connected to a switch to allow the use as parallel or antiparallel (for sham exposure)|
|Sham exposure||A sham exposure was conducted.|
No significant effects of magnetic field exposure, irrespective of exposure time, magnetic flux density, or field direction was found on the survival rate of embryos. Neither any genetic dependency on sensitivity to magnetic field exposure could be revealed.
