Radiography with Beta-Rays

Abstract

SECONDARY electrons, generated by X-rays, have been used for producing shadow images of very thin specimens (Trillat¹, Tasker and Towers²). The use of other radiations (except X-rays), for example, alpha-and beta-rays, recoil atoms and accelerated ions for similar purposes does not seem to have been described. The rapidly increasing availability of radioactive nuclides makes the field very promising. A brief description of radiography with beta rays, for short 'beta radiography' is given below. A report on 'alpha radiography' experiments in this laboratory will be published shortly.
