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.

制造曝光装置的规格如下：主峰工作谐振频率12.6MHz，传输效率72.4%。我们努力提高谐振传输效率。最后，可以满足细胞培养条件，例如37度、100%湿度、5%CO2，并且透射特性显示出85.4%透射效率的单峰。通过电磁场模拟器，在最大功率传输时，细胞暴露的磁场强度约为170 A/m。电场强度为160 V/m左右，比吸收率为24 W/kg。细胞培养环境的稳定性，我们已经完成了基本细胞动力学评价的工作。细胞遗传毒性评价采用微核试验和彗星试验。从这些结果来看，暴露在电磁场下没有观察到显着的影响。
