Figure 3.

Chromosome aberration frequency measured by WCP analysis in cells exposed along the INFN-LNS proton beam SOBP in the presence or the absence of BSH: left panel (A) refers to the entrance position, central panel (B) to mid-SOBP data from Cirrone et al. (14), and right panel (C) to distal position. Error bars depict SE of at least three independent replicates. Data were fitted to a linear-quadratic function Y=Y₀+αD+βD² with Y₀ being the CA frequency in unirradiated cells.
