Abstract: Near the earth’s surface, atmospheric ionization is mainly die to radiations from radioactive minerals in the soil and radioactive gases released from the soil. In order to understand the effect of radioactive deposits at the surface on the atmospheric electrical structure, it is necessary to measure electrical polar conductivities at various altitudes. A Gerdien condenser system has been developed for conducting aerial surveys using a trainer aircraft Pushpak. The payload, its operation on the aircraft, and the results obtained from a survey over Kerala covering different levels of surface radioactivity including a highly radioactive region on the coast are described. The effect of radioactive deposits in enhancing the electrical conductivities has been detected at 2000 ft altitude. It may be possible to use similar measurements for preliminary surveys to detect radioactivity.
