Possible attenuation of the G2 DNA damage cell cycle checkpoint in HeLa cells by extremely low frequency (ELF) electromagnetic fields

Table 2 Perpendicular components of background time-varying and static magnetic fields measured at location of sample holders

Component of System	Active (Yes/No)	Time-Varying Field	Static Field
coils A,B	no	3nT	50.3 μT
coils C,D	no	3nT	45.6 μT
Amplifier and Signal Generator	no
coils A,B	no	3nT
coils C,D	no	3nT
Amplifier and Signal Generator	yes
coils A,B	yes	2mT^*
coils C,D	no	0.38 μT^*
Amplifier and Signal Generator	yes

^* With alternate Helmholtz pairs active the background time-varying field in the non-active coils was found to be 0.38 μT.
