Abstract

The radiation adaptive response phenomenon, also called radioadaptation, is a potential way for modern radiation protection during deep space travels. This can help to improve astronauts’ health after chronic irradiation by relative low dose-rates of ionizing radiation. Adaptive response enhances DNA repair availability due to the stimulation by a stressor. However, this effect is not always observed and is generally narrowed to radioresistant individuals. The presented paper discusses the relation between adaptive response appearance and radiosensitivity (or radioresistance), as well as their possibilities for practical application using the recent simple biophysical model. Additionally, the exemplary case of novel light active radiation shields was also mentioned within this context.
