人体肺磁场是1973年由美国麻省理工学院D·Cohen首先探测出来的。他在探测心脏稳恒直流电流所产生的磁场时,发现这种场不仅来自心脏,而且来自肺部。接着,又有一些国家的有关部门进一步开展了这方面的研究工作。肺磁场是由侵入人肺中强磁性物质(肺磁污染物)在外界磁场的作用下产生的剩余磁场。电焊工、砂轮磨工等,由于他们的工作环境中强磁性粉尘含量较高,有可能产生肺磁场。另外,石棉、煤中也往往夹杂一些强磁性物质,因此石棉工、煤矿工也有可能产生肺磁场。据报导,用肺磁探测法可以探查有害粉尘在肺中的含量和分布,用磁示踪
The human lung magnetic field was first detected by D · Cohen of the Massachusetts Institute of Technology in 1973. When he explored the magnetic field created by steady-state DC currents, he found that the field came not only from the heart but also from the lungs. Then, in some countries, relevant departments carried out further research in this area. Pulmonary magnetic field is the residual magnetic field generated by the magnetic material (lung magnetic contaminants) intruded into the human lung under the action of the external magnetic field. Welders, grinding wheel workers, due to their high magnetic dust in the work environment, may produce lung magnetic field. In addition, asbestos, coal are often mixed with some ferromagnetic material, so asbestos workers, coal miners may also produce lung magnetic field. It has been reported that lung magnetic detection can detect the content and distribution of harmful dust in the lungs,
