Numerous studies have been carried out on the potential effects of an extremely low frequency (ELF-0-300 Hz) magnetic field (MF) on human health. However, there is limited data on the effect of a high exposure level to ELF MFs for a prolonged period. Therefore, the objective of this pilot work was to demonstrate the feasibility of a study evaluating the stress hormone concentrations resulting from a 10-min exposure to a 60 Hz MF of several tens of thousands of µT. In this pilot study, human volunteers were thus exposed for the first time to a 60 Hz, 50 mT MF for a duration of 10 min. Stress hormone levels were measured before (once), during (twice) and after (once) this 10-min exposure period. The small sample size (n = 5) did not allow to conduct standard inferential statistical tests and no conclusion regarding the exposure effects can be drawn. However, this study demonstrates the feasibility of using a simple blood testing material in a protocol testing for the effect of a 10-min exposure to a high MF level in healthy human volunteers. © 2022 Bioelectromagnetics Society.
已经有许多研究探讨了极低频（0-300Hz）磁场（MF）对人类健康的潜在影响。然而，关于长时间暴露于高强度极低频磁场的影响的数据有限。因此，这项初步研究的目的是展示评估人类在 10 分钟内暴露于数万微特斯拉的 60HzMF 后应激激素浓度的研究的可行性。在这项初步研究中，人类志愿者首次暴露于持续 10 分钟的 60Hz、50mT MF 中。在这 10 分钟暴露期间，分别在暴露前（一次）、暴露时（两次）和暴露后（一次）测量应激激素水平。由于样本量小（n=5），无法进行标准推断统计检验，因此无法就暴露效应得出结论。然而，这项研究证明了在健康人类志愿者中使用简单的血液检测材料来测试 10 分钟高磁场水平暴露效应的方案是可行的。© 2022 生物电磁学学会。
