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.
