The work in this article does show nonlinearity of cell damage from alpha radiation in the dose range studied, but the lowest dose studied (5 percent of all cell nuclei hit) is probably several orders of magnitude above the mean lethal dose for any organism. The researchers need to look at linearity through the dose […]
