Efecto de la radiación en las propiedades termoluminiscentes de lavas
Blue thermoluminescence (TL) emission from different lavas of many places (Costa Rica, Canary Islands, Hawaii Islands, Iceland and Italy) corresponding to different eruptions has been studied to know its potential use in the field of dating and retrospective dosimetry. Due to the light emission is l...
