Minimal risk, in regard to prisoners, is defined as: the probability and magnitude of physical or psychological harm that is normally encountered in the daily lives, or in the routine medical, dental, or psychological examination of healthy persons. Note: "Harms," when referring to prisoners, are specifically described as physical or psychological and that the standard minimal risk for prisoners who are research subjects is not based on the daily life of a healthy prisoner, but refers to a healthy person as an absolute standard based on the daily lives of healthy non-incarcerated individuals.
