The principal late effects of ionizing radiation on humans include 
 
 tissue damage 
ic effects 
nant disease - ANS ic effects 
nant disease 
 
 Late or long-term effects of radiation can occur in tissues as a result of chronic exposure or tissues that have survived a previous irradiation months or years earlier. These late effects, such as carcinogenesis and genetic effects, are "all-or-nothing" effects—either the organism develops cancer or it does not. 
 
Examples of late effects of ...
