Radioactive dust can increase rainfall !! Every bad thing has a good side too

Radioactive dust can increase rainfall

Obviously, radioactive dust is usually not a good thing. However, new research has shown that the charged particles generated during the Cold War nuclear tests may cause water droplets to coalesce by triggering electrical charges in the air, thereby increasing rainfall thousands of kilometers away from the test site.

The United States, the Soviet Union and other countries conducted a large number of surface nuclear tests in the 1950s and early 1960s. The residue contains a mixture of demonic radioactive elements that may have a subtle effect on the atmosphere. The charged particles emitted during the radioactive decay process will hit the surrounding atoms and molecules, tear them into pieces and produce more charged particles. Then, the bunch of charged particles will condense on the dust, soot or water droplets in the atmosphere, sometimes making the water droplets too heavy to maintain suspension and fall to the ground.

To verify, atmospheric scientist Giles Harrison of the University of Reading and colleagues studied rainfall records from a weather station on a remote island in northern Scotland during the Cold War. He pointed out that they chose this place because the precipitation there is less likely to be polluted by air, and air pollution may also cause rainfall.

To measure the natural electric field in the atmosphere, the research team used data collected near London-where it is easier to obtain. He pointed out that the levels of radioactive deposits in the air at the two locations may be similar, because when the nuclear test dust in Nevada and Kazakhstan reached the UK, the radiation flow had already spread.

The analysis of the research team showed that there was a strong relationship between the amount of radiation from 1962 to 1964 and precipitation. During this period, the stratosphere was ubiquitously radiated by surface nuclear weapons tests. The researchers reported in Physical Review Letters the day before yesterday that at the Scottish site, the clouds were thicker, and on days when the radiation was above average, precipitation increased by 24% (based on measurements of atmospheric electric fields ).

Generally, particles with opposite charges will attract, and similar charges will repel. Rhodes College's theoretical physicist Banerjee pointed out that larger objects like droplets can attract each other even if they have the same total charge. This is because when the droplets are close to each other, the charge will move, so that the closest part of the droplet will form the opposite charge, thereby attracting.

He said the findings of the meteorological research team may be instructive for small-scale weather control technology. He suggested that by using spark generators or similar devices to introduce large amounts of charged particles into the clouds, researchers can "coax" the droplets there to coalesce. Harrison believes that this can also help astronomers better understand the weather patterns of other planets such as Jupiter and Neptune, whose atmospheres are filled with charged particles produced by the impact of lightning or cosmic rays.
