Chemical Stage : (few seconds)


                                  The free radicals and oxidising agents may attack the complex

                                  molecules which form the chromosomes.






                                  Biological Stage : (tens of minutes to tens of years)






                                  The following may occur:


                                  a. early death of the cell

                                  b. prevention or delay of cell division


                                  c. permanent modification which may be passed to the progeny
