An approach to the use of synchrotron radiation for investigating radiation effects on cultured mammalian cells in the range from 160 to 254 nm.

An experimental system with a humidified irradiation chamber was developed to investigate the effects of monochromatic synchrotron radiation on cultured mammalian cells (HeLa). The dependence of the sensitivity on the wavelength based on D0 showed a minimum at about 190 nm in the range of 160 to 254 nm.
