Discrimination of tracks of photofission fragments with very high backgraund of alpha-particles and electrons in nuclear emulsions

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

With common drugs used in photography such as amidol, boric acid, sodium sulfite and potassium bromide, a developing bath was prepared which permits a complete discrimination of the tracks of highly ionizing particles, such as fission fragments, in the presence of strong background radiation such as that produced by the electrons from a 2000 röntgen X-ray dose and a background of 1011 α-particles/cm3.

Riassunto

Con i comuni prodotti usati in fotografia come l’amidolo, l’acido borico, il solfito di sodio ed il bromuro di potassio si è preparato un bagno di sviluppo che permette di fare una perfetta discriminazione delle tracce di particelles altamente ionizzanti, come i frammenti della fissione, in presenza di una forte radiazione di fondo, quale quella prodotta dagli elettroni di una dose di raggi X di 200 röntgen o da un fondo di 1011 particelle α/cm2.
