The Recent Status of Secular Variation of Atmospheric Electricity (?)
Kondo, G.
Abstract
In the previous paper (1958), we described that the atmospheric electricity was changed owing to the radioactive fall-out of the recent nuclear detonations. In this report, the results of the subjects since I. G. Y. 1957-1958 is described.
a : Both of the variations of the potential gradient and conductivity are connected with the variation of the radioactivity of fall-out.
b : The variation of the conduction current is not connected with that of fall-out.
c : It takes about two years to be free from the effect of fall-out on the atmospheric electricity.
