Good point uvdiv: if the ionization events are sufficiently rare in both cases we ought to be able to treat them as cumulatively equivalent. I guess it would depend on the error correction time and the size of the affected nucleotide sequence, especially in a double-break error. The dose delivered by these scanners is probably well-below that threshold. My remaining concern would be that the biological effects of this particular energy regime are as-of-yet uncharacterized.
