概要: 金沢大学理工研究域電子情報学系<br />Electromagnetic devices such as superconducting magnets, magnetically levitated vehicles and magnet … ic resonance imaging(MRI) create strong magnetic fields within their immediate vicinity. This has generated some concerns over the effects that these fields may have on the outside environment and in particular on living organisms. 50/60Hz magnetic fields are of special concern because living organisms are exposed to them on a continuing basis.We investigate the influence of a strong 60Hz AC magnetic field of 1.2T on organisms. The high AC magnetic field is generated by using a multilayer eddy-current type AC magnetic generator developed in our laboratory. In this paper, in vitro experiments were performed with biochemical reactions, enzyme and restriction endonuclese activities.As a result, the magnetic field inhibited catalase activity slightly only in biochemical reactions. Other reactions such as β-galactosidase activity and restriction endonuclese activity were not influenced at all. The results suggest that high 60Hz AC magnetic fields may influence biological functions in some organisms. 続きを見る
