Unanticipated late effects in neutron and heavy ion therapy, not attributable to overdose, imply a qualitative difference between low and high LET therapy. We identify that difference as ‘ion kill’, associated with the spectrum of z/β in the radiation field, whose measurement we label ‘ion-kill dosimetry’.
