Based on microdosimetry considerations [ICRU, 1983], cellular survival versus dose of low-LET (X-ray) radiation became described by an exponential expression with terms linear and quadratic with dose (the so-called “alpha-beta” or linear-quadratic description), where a purely exponential survival (with an “alpha” term only) dose.

Based on several clinical studies, ICRU recommended a minimum accuracy of ±5 % in absorbed dose to a target volume (the figure was later interpreted as representing 2 SD (IAEA 2000)). With the publication of ICRU 91, certain plan evaluation parameters have been standardized and recommended for prescribing, recording, and reporting of stereotactic treatments.
