Atmospheric electricity

Atmospheric ions are important in controlling atmospheric electrical properties and conmumications and, in certain circumstances, aerosol fomiation [128. 130. 131. 138. 139, 140. 141. 142, 143, 144 and 145]. In addition, ion composition measurements can be used to derive trace neutral concentrations of the species involved in the chemistry. Figure A3.5.11 shows the total-charged-particle concentration as a frmction of...

Radon daughter ions and the ionization caused by the decay chains of radon and thoron in indoor air play important roles both from the contribution made by the daughter product positive ions to internal dose and from the effects of ion-pair production on the indoor atmospheric electrical parameters.

Electrostatic and Electrostatics. Electrostatic pertains to static electricity or electricity at rest. It can be produced by friction or atmospheric electricity. Electrostatics is the science of static electricity. Electrostatic discharges are frequent causes of fires and explosions. This problem is discussed under ELECTRICITY, EXTRANEOUS AND HAZARDS ASSOCIATED WITH IT Refs 1) Hackh sDict (1944), 301-L... 

RECOMBINATION. The process by which a positive and a negative ion join to form a neutral molecule or other neutral particle. In the literature of atmospheric electricity, tins term is applied both to the simple case of the capture of free electrons by positive atomic or molecular ions, and also to the more complex case of the neutralization of a positive small ion by a negative small ion, or a similar (but much more rare) neutralization of large ions,...

Cavendish was fascinated by such stories. He read also about Franklin s experiments with atmospheric electricity—how he had flown a kite in the summer of 1752 and felt the electric shock of the thunderstorm. This force must be a powerful weapon, thought Cavendish, for a year later Dr. Georg Rich-mann who tried the same experiment had been killed. Here was a potent instrument which the chemist might use to solve great mysteries.
