Vertical atmospheric DC electric field at ground level, or potential gradient (PG), suddenly dropped by one order of magnitude at Kakioka, 150 km southwest from the Fukushima Dai‐ichi nuclear power plant (FNPP) right after the plant released a massive amount of radioactive material southward on 14 March, 2011. The PG stayed at this level for days with very small daily variations. Such a long‐lasting near‐steady low PG has never been observed at Kakioka. The sudden drop of PG with one‐hour time… 
Effect of enhanced ionizing radiation on the cloud electricity after the Fukushima nuclear accident
The vertical downward component of the DC atmospheric electric field, or potential gradient (PG), at Kakioka 150 km southwest of the Fukushima Dai-ichi Nuclear Power Plant (FNPP1) was analyzed before
Settlement process of radioactive dust to the ground inferred from the atmospheric electric field measurement
Abstract. Radioactive materials from the accident at Fukushima Dai-ichi nuclear power plant (FNPP) in March 2011 spread over a large area, increasing the atmospheric electric conductivity by their

Lord Kelvin's atmospheric electricity measurements
Abstract. Lord Kelvin (William Thomson) made important contributions to the study of atmospheric electricity during a brief but productive period from 1859–1861. By 1859 Kelvin had recognised the
