Everyone knows that any photon at the higher end of the em spectrum can ionize matter(hence the name ionizing radiation)

But is it possible to achieve the same results by firing a barrage of low energy photons in quick succession?

Do quantum effects have to be taken into account?

Is the energy required to free an electron(work function) spent on overcoming the electrostatic attraction between the electron and the nucleus? Or is it spent somewhere else?
