The aim of this work is to study the relationship between the pre-earthquake emissions of radon and ULF/ELF (1–30 Hz) atmospheric electromagnetic radiation. The problem is considered on the example of the 2011 Tohoku earthquake. Radon, ionizing air, creates ions—centers of condensation of water vapor. As a result of condensation, heat is generated. It results in growth of air temperature and decrease in its humidity. This phenomenon serves as an indicator of air ionization. We used data from 20 Japan Meteorological Agency (JMA) weather stations located on Honshu Island to estimate any changes in temperature and humidity over ± 20 days from the date of the main shock. At the same time, we monitored the intensity and location of the source of ULF/ELF radiation using three induction magnetometers belonging to Chubu University. We compared the times and locations of observed signs of ionization and electromagnetic radiation to find out their relationship. It turned out that they are independent, since their dates and localizations do not match. In addition, we found intense ionization of the air after March 11 over a large area of Honshu Island, caused by radiative radiation from the nuclear disaster at the Fukushima Daiichi nuclear power plant. However, this phenomenon did not cause low-frequency atmospheric electromagnetic radiation either. These suggest that there is no direct relationship between air ionization and ULF/ELF radiation. This is true at least for this case, given the island nature of the land and oceanic EQs.

这项工作的目的是研究地震前of排放与ULF / ELF（1–30 Hz）大气电磁辐射之间的关系。以2011年东北地震为例考虑了这个问题。air使空气离子化，产生离子-水蒸气冷凝的中心。由于凝结，产生热量。这会导致气温升高，湿度降低。该现象可作为空气电离的指标。我们使用了位于本州岛的20个日本气象厅（JMA）气象站的数据来估算自主震发生之日起±20天内的温度和湿度变化。同时，我们使用属于中部大学的三台感应磁力计监测了ULF / ELF辐射源的强度和位置。我们比较了观察到的电离和电磁辐射迹象的时间和位置，以找出它们之间的关系。事实证明，它们是独立的，因为它们的日期和本地化不匹配。此外，由于福岛第一核电站核灾难的辐射辐射，我们在本州岛的大片区域发现了3月11日以后空气中的强烈电离现象。但是，这种现象也不会引起低频大气电磁辐射。这些表明空气电离与ULF / ELF辐射之间没有直接关系。考虑到陆地的岛屿性质和海洋情商，至少在这种情况下是这样。因为它们的日期和本地化不匹配。此外，由于福岛第一核电站核灾难的辐射辐射，我们在本州岛的大片区域发现了3月11日以后空气中的强烈电离现象。但是，这种现象也不会引起低频大气电磁辐射。这些表明空气电离与ULF / ELF辐射之间没有直接关系。考虑到陆地的岛屿性质和海洋情商，至少在这种情况下是这样。因为它们的日期和本地化不匹配。此外，由于福岛第一核电站核灾难的辐射辐射，我们在本州岛的大片区域发现了3月11日以后空气中的强烈电离现象。但是，这种现象也不会引起低频大气电磁辐射。这些表明空气电离与ULF / ELF辐射之间没有直接关系。考虑到陆地的岛屿性质和海洋情商，至少在这种情况下是这样。这种现象也不会引起低频大气电磁辐射。这些表明空气电离与ULF / ELF辐射之间没有直接关系。考虑到陆地的岛屿性质和海洋情商，至少在这种情况下是这样。这种现象也不会引起低频大气电磁辐射。这些表明空气电离与ULF / ELF辐射之间没有直接关系。考虑到陆地的岛屿性质和海洋情商，至少在这种情况下是这样。
