Abstract

IT is well known that the large numbers of neutrons released during nuclear bomb detonations (0.5 kgm. neutrons per megaton explosion)1 can induce high levels of radioactivities in the hardware and associated structures of the apparatus. Of particular interest is iron-55, an X-ray emitter with a half-life of 2.6 years, formed by (n, 2n) and (n, γ) reactions on iron-56 and iron-54, respectively.
