Abstract

The fading of αparticle tracks in Ilford C 2 emulsions has been studied After irradiation by an alpha source the photographic plates were stored in air at various temperatures for a period of four months They were then compared with a standard plate which had been developed immediately after irradiation Amongst the plates stored at35 °C no particle track fading was noticed neither was a diminution in the number of tracks Amongst those plates stored at 4°C and at 15 °C the grain density of the particle tracks had lessened and respective percentage losses of 38 and 72 in the number of tracks were noticedSi è studiata l’evanescenza delle tracce di particelle α nelle emulsioni Ilford C2 Dopo irradiazione con una sorgente α le lastre furono oonservate in aria a varie temperature per un periodo di quattro mesi Furono poi confrontate con una lastra campione sviluppata immediatamente dopo l’irradiazione Nelle lastre conservate a35 °C non fu riscontrata alcuna evanescenza nè diminuzione del numéro di tracce Nelle lastre conservate a 4 °C e a 15 °C la densità di grani delle tracce delle particelle è diminuita e furono osservate delle diminuzioni percentuali del numero di tracce rispettivamente del 38 e del 72
