[Biometrical analysis in the radiobiology works of N. V. Luchnik]

The contribution of the famous Russian geneticist and biophysicist N. V. Luchnik into biometrical analysis of radiobiological data is discussed. His works on radiation mortality of mice and the process of post-radiation repair of chromosome aberrations are thoroughly observed. The conclusion of necessity to develop biometrical analysis as separate part of biometry is made.
