Abstract
RADIATION intensity is a useful parameter for studying mechanisms in radiation chemistry. The maximum intensity of electromagnetic radiation previously obtainable was 1010 rads/s from particle accelerators. We have used the intense burst of radiation from an underground nuclear explosion to obtain dose rates of 1012 to 1013 rads/s and to study the radiation chemistry of a variety of simple chemical systems. Chloroform was chosen for a preliminary study because intensity effects on the yield of its radiolytic products have been reported for irradiation at lower dose rates1,2. Our results not only support the mechanism proposed for lower intensities by Werner and Firestone3, but indicate that at higher dose rates CHCl3 is no longer successful in scavenging all the radiolytically produced chlorine atoms (one of the primary dissociation products).
