No threshold has to my knowledge been seen on the level of point mutations, 
chromosomal aberrations etc. The micronucleus assay gives a straight line 
down to a level of about 2 mGy per cell generation. The resolution limit is 
of course determined by statistics (it could probably be pressed down to 
about 1 mGy/generation with "reasonable" costs). Specific chromosomal 
aberrations are known to be associated with certain tumors. Knocked out Rb 
functions (due to point mutations, non-disjunction, deletions etc) result in 
tumors. There is more along this line.

My personal ideas only (shared by some others however),
