The authors performed an examination of the degree of lung contamination by magnetic compounds present in gases originating during welding in 33 persons divided into four groups. The measurement was performed by a noninvasive magnetometric method using a high sensitive SQUID and second degree gradiometric antenna with presumed maximum sensitivity of 60 micrograms of magnetic compound/cm3. In the selected three groups of welders working for a long period of time under the conditions of exposure, the changes of the magnetic field were particularly evident in the group working in small confined spaces. It has become obvious that further improvement in the accuracy of the detected results in the lung may be reached in the subjects by changing the polarity of magnetization. (Fig. 4, Ref. 13.).
作者对33名分为四组的人员进行了检查，这些人员在焊接过程中产生的气体中存在磁性化合物，检测其肺部受污染的程度。测量采用非侵入性磁力测量法，使用高灵敏度超导量子干涉仪和二阶梯度天线，假定最大灵敏度为60微克磁性化合物/立方厘米。在选定的三组长期在暴露条件下工作的焊工中，在小密闭空间工作的组中磁场变化尤为明显。显然，通过改变磁化极性，可进一步提高这些受试者肺部检测结果的准确性。（图4，参考文献13）
