  == Injury to operators ==  Not only does the source listed(3) for the 'A Common Myth' paragraph not say anything about it being a myth that harm would come to the operators, 2 out of the 3 sources listed contradict that statement and in fact suggest that the crew would be exposed to lethal amounts of radiation.  I've been told by george that it exist and is widely sourceable when it doesn't exist - atleast 4 times - george, how about checking to see if it actrully exist, or after I fact tagged it like you asked me to, actrully check it.  I searched all over the 3rd cited source of which you said that myth is explained and it says absolutely nothing, so... what's the deal? Maybe you could paste it here and while your at it explain this:  http://www.youtube.com/watch?v=khyZI3RK2lE  History channel doesn't know what they are talking about then either?  There rest I've taken from the second source, please read it this time.  ^ Guntruck.com Davy Crockett page, accessed Oct 20, 2006 http://www.guntruck.com/DavyCrockett.html     Okay - so what does all that mean? With very small battlefield atomic weapons like Davy Crockett the flash effects upon detonation shrink to insignificance - with prompt radiation effects dominating the characteristics of the blast - Davy Crockett isn't a weapon deployed for a spectacularly big bang - which tended to negate its original purpose.    In a Davy Crockett fission explosion, the range for lethal exposure actually extends some distance beyond the blast injury range - which placed the operators in peril. At one setting above its minimum, a 20 ton TNT explosive blast yield for Davy Crockett results in the following types of damage:    The maximum range that exposed troops would experience 3rd degree flash burns from the Blast Center is 90 meters (297 feet) Examples of Significant Radiation Effects:    200 REM causes sterility, and increased cancer risk, temporary immune system suppression. In our example this dosage occurs at a little under 500 meters (1,650 feet) from ground zero.    600 REM is considered a fatal dose - 50% fatality rate. This dosage occurs just inside 400 meters (1,320 feet) from blast center. At the 20 ton TNT yield setting, this would become the minimum distance the operators would want to select for setting the Davy Crockett projectile to detonate.    1000 REM is 100% lethal - perhaps a soldier might make it back to a rear area or Stateside before death. 1000 REM will kill those solders such exposed within two weeks. Why did I say Stateside? This dosage occurs outside 300 meters from blast center - which is also the minimum detonation range (also meaning the shortest detonator timer setting option) of the Davy Crockett. However, the selection of the minimum detonation range when firing the Davy Crockett in this example would spell certain death for the weapon operators - even at this low setting. This is the edge of Davy Crockett's lethal zone. The weapon's operators could be evacuated and transported back Stateside for treatment, but ultimately would perish.    To protect the operators of the Davy Crockett Atomic Battle Group System, the explosive yield would have to be dialed down to shorten the lethal prompt ionizing radiation range enough for their safety. Naturally, doing that decreases the destructive potential of the weapon - defeating the purpose of deploying it in the first place.
