Muna 2003, NASA's Lyndon B.

Pakutanga, pakanga paine humwe uchapupu hwekuti rudzi urwu rwezinga rakaderera, kusvibiswa kwenguva refu hakusi ngozi sezvakambofungidzirwa; uye kuti radiation hormesis inoitika. Zvisinei, migumisiro kubva kuongororo ye2006 yakaratidza kuti mapurotoni anobva kumhepo yemhepo inogona kukonzera kukuvadza kwakanyanya kuDNA sezvakambofungidzirwa, zvichiita kuti vashandi vemuchadenga vave pangozi yakakura yekenza nezvimwe zvirwere.
rudzi urwu rwomutero wakaderera, unopfuurira rwemwaranzi harusi rune ngozi zvikuru sezvakambofungwa; uye kuti radiation hormesis inoitika
