Radio frequency electromagnetic fields (RF) have been shown to modify the concentrations of the radical O, HO and cancer cell growth rates at exposure levels below those that cause significant heating. Reactive oxygen species (ROS) are both signaling molecules and species that can do damage, depending on timing, location and concentrations. We briefly look at some mechanisms by which electromagnetic fields can modify the concentrations of ROS and some of the feedback and repair processes that lead to variable biological effects. Of particular interest are the role of radical pairs and their spins, which have received considerable attention recently, and the role of feedback in biological systems, to which less attention has been paid.
射频电磁场（RF）已被证明可以在不引起显著加热的暴露水平下，改变自由基 O、HO 和癌细胞生长速率的浓度。活性氧（ROS）既是信号分子，又是可以造成损害的物质，这取决于时间、位置和浓度。我们简要地看一下电磁场可以改变 ROS 浓度的一些机制，以及导致不同生物效应的一些反馈和修复过程。特别感兴趣的是自由基对及其自旋的作用，这在最近受到了相当多的关注，以及生物系统中的反馈作用，这方面的关注较少。
