自由基对机制进行了讨论，作为一个可能的途径，使环境强度的磁场可能会影响生物系统。它被公认为化学中可再现场效应的起源，即使在非常低的磁场强度下也可以观察到这些效应，包括地磁场。在这里，它试图给出一个描述，这可能有助于在生物实验室工作的实验人员设计与他们的工作相关的测试。该机制是很好地理解和具体的理论方法是采取探索和强调的自由基对的寿命和精确的化学性质的自由基，其中包括它在影响的大小低举行的效果的重要性。进一步的后续过程可能是必要的，以引起这种主要效应，以获得生物学意义。提供的参数表明，自由扩散对（F-对）的自由基的遭遇不太可能在生物学中产生显着的影响。
The radical pair mechanism is discussed as a possible route whereby a magnetic field of environmental strength might affect a biological system. It is well established as the origin of reproducible field effects in chemistry, and these can be observed even at very low magnetic field strengths, including that of the geomagnetic held. Here it is attempted to give a description which might assist experimentalists working in biological laboratories to devize tests of its relevance to their work. The mechanism is well understood and a specific theoretical approach is taken to explore and emphasize the importance of the lifetime of the radical pair and the precise chemical natures of the radicals which comprise it in affecting the size of the low-held effect. Further subsequent processes are likely necessary to cause this primary effect to attain biological significance. Arguments are provided to suggest that the encounters of freely diffusing pairs (F-pairs) of radicals are unlikely to produce significant effects in biology.
