Examples contradicting the LNT hypothesis selected from the literature from the last 100 years. a Prolonged life of flour beetles after multiple daily low doses (upper panel) or a single low dose (lower panel) of X-rays compared to nonirradiated controls (dashed horizontal curves) Modified from [5]. b Observed decreases (opposite to theory) in lung cancer mortality rates (corrected for smoking) with increasing residential exposure to radon in 1,601 (90% of all) US counties (NOAEL no adverse effect level). From data reported in [9]. c Increased life time (solid curves) of Nagasaki A-bomb survivors exposed to low dose radiation compared to nonexposed controls (dotted curves) [8]. d Mortality of 10,000 occupants of 1,700 ⁶⁰Co-contaminated apartments in Taiwan who received a mean yearly dose of 49 mSv or an accumulated dose of 400 mSv during their total stay (lower curve) versus mortality in the general population (upper curve). In the exposed population, the rate of congenital malformations was only 7% of that in the general population [10]
