Typical graph showing the probit analysis of skin damages for Guizhou miniature pig. The incident beam diameter and exposure duration was 1.96 cm and 3.0 s, respectively. The red square points were experimentally determined damage probabilities at 1 h post exposure for corresponding power levels. By probit analysis, the ${\mathrm{ED}}_{50}$, the fiducial limits at the 95% confidence level, and the probit slope could be determined.
