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

Data from the radiation monitoring network surrounding the Fukushima Dai-ichi Nuclear Power Plant (FNPP) revealed that the radiation levels generally decayed faster at a highly-contaminated area than
Nature of Relationships Between Atmospheric Electricity Parameters at Ground Surface and Air Ionization on the Basis of Nuclear Accidents in Power Plants and Weapons Tests
In this work we present an analysis of selected atmospheric electricity parameters, measured at the Geophysical Observatory in Świder (near Warsaw, Poland), in a review of the major events that
Fair-weather atmospheric electric field measurements at Gulmarg, India
In the present study, the atmospheric electric field observations are reported at Gulmarg station, Kashmir (34°05′N; 74°42′E) for a period of 1 year: June 2019–May 2020. The observation site is
Observation of Atmospheric Electricity Parameters at Boso Peninsula, Japan
The total electron content (TEC) and the thermal infra-red (TIR) anomalies preceding large earthquakes have been reported and they considered the most promising precursory phenomena. To explain these
Atmospheric electric field measurements in urban environment and the pollutant aerosol weekly dependence
The weekly dependence of pollutant aerosols in the urban environment of Lisbon (Portugal) is inferred from the records of atmospheric electric field at Portela meteorological station (38°47′N,
Improvement of Instantaneous Point Source Model for Simulating Radionuclide Diffusion in Oceans under Nuclear Power Plant Accidents
Simulation methods have become an important tool to reveal radionuclide migration during accidental radionuclide releases and predict influences of accidents on the marine environment. The
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

The global atmospheric electric circuit , solar activity and climate change
The study of the global atmospheric electric circuit has advanced dramatically in the past 50 years. Large advances have been made in the areas of lightning and thunderstorm research, as related to
Radioactive fallout and secular effects in atmospheric electricity
Changes in the potential gradient at six observatories in Britain, Japan, and Portugal, are examined over the period 1950 to 1964. The changes follow the same pattern at all six stations. The

Effects of radioactive fallout from a nuclear power plant accident on electrical parameters
Continuous recordings of atmospheric electric parameters were carried out in Uppsala, Sweden. Because of the accident in the nuclear power plant in Chernobyl, USSR, a rainfall on April 27, 1986,
Increased occurrence of lightning flashes in Sweden during 1986
As a result of the accident in the nuclear power plant at Chernobyl, USSR, a considerable increase in radioactive background radiation was noted in some regions of Sweden. In areas with high

The Earth’s global atmospheric electric circuit depends on the upper and lower atmospheric boundaries formed by the ionosphere and the planetary surface. Thunderstorms and electrified rain clouds
Quantitative estimation of global circuit
Quantitative estimations of the global circuit parameters have been made to test the terrestrial and/or extraterrestrial controls of the global atmospheric electric circuit. A global model of
Some calculations on radioactive fallout with especial reference to the secular variations in potential gradient at Eskdalemuir, Scotland
SummaryFrom a study of the variations in potential gradient at Eskdalemuir, Scotland, it is shown that the radioactivity there has roughly doubled during the past six years; in other words, a
