Figure 5
The dose response for radical trapping in lysozyme crystals irradiated with 70 keV X-rays at 4 K. Data for the concentration of total trapped radicals, R(tot), are shown for three different crystals using open black symbols (left y axis). Data for radicals formed by reduction of RSSR, R(SS), are shown using closed blue symbols (right y axis). See text regarding the normalization of the data using the measured mass of crystal 1. The curves were obtained by a nonlinear least-squares fit of the data using equations (6)[link] and (7)[link] with the parameters detailed in the figure.  [article HTML]
