Exposure details   Extremely Low Frequency Magnetic Fields Do Not Elicit Oxidative Stress in MCF10A Cells. by Hong MN, Han NK, Lee HC, Ko YK, Chi SG, Lee YS, Gimm YM, Myung SH, Lee JS published in: J Radiat Res 2012; 53 (1): 79 - 86 General information: Cells were divided into three different groups: i) sham exposure group ii) experimental group exposed to ELF-MF iii) positive control group exposed to gamma radiation Exposure 1: Main characteristics frequency: 60 Hz type of field: magnetic field Exposure setup exposure source/structure: coil(s) exposure time pattern: continuous for 4 h chamber details: exposure system was kept in an incubator at 37°C (±3°C); size of Petri dishes: 100 mm setup details: field generator consisted of four square-shaped coils and one cage with three testing floors sham: sham exposure was performed add. information: magnetic field shielding system using ferrite material was adopted to shield strong magnetic fields in the outer of the exposure system Exposure parameters parameter: value: type: method: remark: magnetic flux density  1 mT  max value  measured and calculated  fixed value at the center of the middle floor  additional information: voltage fluctuation rate and harmonic rate of power quality were under 1%; spatial variation of magnetic field was under 3% measurement and calculation details: magnetic field distribution was calculated at the middle floor; fields at various other points were measured Return to general data Glossary: 60 Hz, cells, coil, ELF, exposed, exposure, gamma radiation, incubator, magnetic flux density, MF, petri dishes, positive control, power, sham exposure, voltage
