Surviving fraction of V79 cells as a function of mean cellular uptake of radioactivity (lower abscissa) and mean absorbed dose to the cell nucleus (upper abscissa) after exposure to 212Pb(PDC)2. The dose response is exponential with a mean lethal uptake of 0.35 mBq/cell and mean lethal dose of 1.0 Gy when the recoil energy of the 212Pb daughters is ignored.
