A specific and correlative study of natural atmospheric radioactivity, condensation nuclei and some electrical parameters in marine or urban sites
Description
In order to determine the correlations between the following atmospheric parameters: radon and condensation nuclei concentrations, total conductivity and space charge, we analysed their behavior over a long period, in connection with meteorological data. We simulaneously studied the equilibrium state between 222Rn and its short-lived daughters pointing out a radioactive desequilibrium as a function of the meteorological conditions. Simultaneously, we established average experimental curves of cumulated particle size distributions of natural radioactivity in the air, differentiating urban and marine influences. Finally, a comparison between the various parameters showed that the total conductivity greatly depends on condensation nuclei and radon concentrations in the air

Afin de determiner des correlations entre les parametres atmospheriques suivants: concentration en radon de l'air, concentration en noyaux de condensation, conductivite totale et charge spatiale, nous analysons leurs comportements sur une longue periode, en fonction de differentes donnees meteorologiques. Simultanement, nous etudions le degre d'equilibre entre le radon et ses descendants a vie courte, mettant en evidence un desequilibre radioactif variant en fonction des conditions meteorologiques. En meme temps, nous etablissons des repartitions granulometriques experimentales moyennes de la radioactivite naturelle dans l'air en distinguant l'influence urbaine de l'influence maritime. Enfin, la comparaison entre les differents parametres montre que la conductivite totale depend fortement de la concentration de l'air en noyaux et en radonFiles
