I have a big gripe with this article, there's an apples-to-oranges that is completely invalid. Harry Daghlian, died from an acute exposure to 5.9Sv. Albert Stevens received a slow dose of 64Sv and doesn't seem to have died from it. (To those who object to it being different forms of radiation: the Sievert is already scaled to human response.) The problem is there are two separate threats. An acute exposure has an LD50 of 4Sv. By the LNT theory the chronic exposure LD50 is 100Sv. Entirely separate mechanisms, just because both are due to radiation doesn't mean they should be compared. (Simple test: what's your chance of surviving an hour in 1000F? None, of course. Should we conclude that you have no chance of surviving 100F for 10 hours??) (I do have a gripe with the LNT theory, though--a straight line is the simplest curve to fit but the data is very sparse and has no data points anywhere near the zero. A parabola is at least as good a fit and probably a better fit if you include the no-data cases--studies of populations that were exposed but no excess mortality is seen.)
