A BRIEF INTRODUCTION TO RADIATION CHEMICAL ENGINEERING
When matter is irradiated by
gamma radiation from the
radioisotopes Co-60 or Cs-137 or electron beams from an
accelerator (less than 10 mega electron-volts) they may form
excited atoms, molecules, free radicals or ions,. which may in
turn induce initiatory chemical reactions.
used to produce chemical products, it is called

advantages that the process is simple, easy to control, energy-
saving and non-polluting. Some chemical products cannot be
manufactured through other means.
Radiation Cross-linking
Radiation cross-linking occurs when two or more high polymer
long chain molecules approach each other and join together

Chemical products manufactured by radiation cross-linking
include electric wires, cables and ancilliary products, thermal
shrinking tubes and films, foamed plastic and rubber.
Electric wires, cables and ancilliary products manufactured
with the aid of radiation cross-linking are characterized by
