( 1981 a , b ) for the observation of the radiation responses of live cultured mammalian cells with an incubated phase-contrast microscope : the colony-forming abilities of single cells obtained by selective detachment of mitoses ( instead of cell pairs as previously ) may now be followed individually and may be directly compared with chromosome damage detected after post-radiation mitosis ( m1 ) .
