Nuclear Inst. and Methods in Physics Research, B > 2014 > 330 > Complete > 47-54

Energetic particles exist ubiquitously in nature, and when they hit DNA molecules in organisms, they may induce critical biological effects such as mutation. It is however still a challenge to measure directly and quantitatively the damage imposed by the energetic ions on target DNA molecules.
