Muons penetrate much further than X-rays, they do essentially zero damage, and they are provided for free by the cosmos.

EVOLUTION Correction for “Evidence of directional and stabilizing selection in contemporary humans,” by Jaleal S. Sanjak, Julia Sidorenko, Matthew R. Robinson, Kevin R. Thornton, and Peter M. Visscher, which was first published December 18, 2017; 10.1073/pnas.1707227114 (Proc Natl Acad Sci USA 115:151–156).
The authors note that on page 152, right column, first full paragraph, line 10, “–0.0086 ± 0.003” should instead appear as “0.0086 ± 0.003.”
The authors also note that on page 1 of the Supporting Appendix, second paragraph, lines 6–8, “All phenotypes, except LRS, measured in the set of 376,366 post-reproductive white-British ancestry samples were split by sex and then scaled to mean zero and variance one” should instead appear as “All phenotypes measured in the set of 376,366 post-reproductive white-British ancestry samples were split by sex and then scaled to mean zero and variance one; the standard deviation of rLRS before scaling was 0.62 for females and 0.65 for males.” The SI has been corrected online.
