| Research Abstract |
For manufacturing of exposure device, the specifications are as follows; the main peak operating resonance frequency 12.6MHz, a 72.4% transmission efficiency. We made efforts to improve the resonance transmission efficiency. Finally, it is possible to satisfy the cell culture conditions, such as the 37 degree, 100% humidity, 5% CO2, and the transmission characteristics shows a single peak at 85.4% transmission efficiency. By the electromagnetic field simulator, the magnetic field strength for cell exposure was about 170A/m at maximum power transmission. In addition, the electric field strength was about 160V/m, and the specific absorption rate was 24W/kg. The stability of the cell culture environment, we had performed that the work on the evaluation of the fundamental cell kinetics. For cellular genotoxic assessment, we had done both micronucleus test and comet assay. From these results, no significant effects were observed under exposure to electromagnetic fields.
