Did Nobel Laureate, Hermann Muller knowingly suppress evidence on radiation effects in 1946???

Did Nobel Laureate, Hermann Muller (http://www.nobelprize.org/nobel_prizes/medicine/laureates/1946/muller-lecture.html), knowingly suppress evidence on radiation effects in 1946 concluding there is no safe level of radiation exposure???!!! a new study suggests yes, Calabrese adds, "This isn't an academic debate, it's really practical, because all of our rules about chemical and low-level radiation are based on the premises that Muller and the National Academy of Sciences' (NAS) committee adopted at that time. Now, after all these years, it's very hard when people have been frightened to death by this dogma to persuade them that we don't need to be scared by certain low-dose exposures."' read more to decide for yourselves: http://www.umass.edu/newsoffice/newsreleases/articles/136706.php ... see also: http://www.spacedaily.com/reports/Nobel_Laureate_may_have_suppressed_evidence_on_radiation_effects_in_1946_999.html ... and http://ts-si.org/horizons/30988-edward-calabrese-alleges-hermann-muller-suppressed-radiation-effects-evidence-in-1946
