English: Analysis of the total radioactivity rings of wood (Scots pine)
After the Second World War and the atomic bomb , many atmospheric nuclear tests were (in 1950) released large quantities of various radionuclides and radioactive isotopes (including carbon 14) in the air, enough to double the normal rate of C-14 from the atmosphere , and due to the increase in biomass and necromass (first panel). The right-hand peak corresponds to the release into the atmosphere from C-14 by the Chernobyl disaster. Note: there is a slight spread in tree rings corresponding to the months or years prior to an event. Français : Analyse de la radioactivité totale cernes de bois (Pin Sylvestre) Après la seconde guerre mondiale et la bombe atomique, de nombreux essais nucléaires atmosphériques ont (dans les années 1950) libéré une grande quantité de divers radionucléides et radio-isotopes (dont carbone 14) dans l'air ; assez pour doubler le taux normal de de C-14 de l'atmosphère, et par suite pour le faire augmenter dans la biomasse et nécromasse (partie gauche du graphique). Le pic de droite correspond au relargage dans l'atmosphère de C-14 par la catastrophe de Tchernobyl. Remarque : on observe une légère diffusion dans les cernes correspondant aux mois ou années précédent un évènement. |
