【摘要】 本文论述对某石棉制品厂93位男性工人用局部磁化法和磁通门梯度计测量肺磁场的方法和结果。对有、无石棉肺病者及不同工龄的工人比较了其前胸12个测量点肺磁场的平均值,发现了该值对继续接尘的石棉肺患者和可疑石棉肺者在统计学上显著地高于无石棉肺者,而且该值随工龄增大而增加。文中建议对于在含铁磁性微粒粉尘中工作的工人进行动态的肺磁场测量,这至少可作为肺内蓄尘量的定量测定法而可能对尘肺的防治有重要作用。更多还原

【Abstract】 Magnetic field at chest of 93 maleworkers exposed to asbestos dust in anasbestos products factory in China wasstudied by localized magnetizing andfluxgate gradiometer.The average fie-ld intensity of 12 measuring points ot-er anterior chest wall was comparedamong asbestosis and non-asbestosisworkers.Both had different lengthof working periods.The field intensityof workers with asbestosis and thosesuspected to be asbestosis by Xrayexamination was significantly higherthan that of non-asbestosis workers.It was also found that the field in-tensity increased with the length ofworking periods.It was suggested thata dynamic measurement of magneticfield of the lung in workers exposed todust containing ferromagnetic particlesmay serve as a Quantitative determinationof the amount of dust accumulated intheir lungs,that may provide someimportant means for the prophylacticof this disease.更多还原
