Subject: No Protective Gear Plutonium-238 only emits alpha radiation (and VERY small amounts of gamma/neutron) which is virtually harmless to humans. Minimal shielding is required, if any.



Same with uranium-235.



The one route that may cause significant damage is if a plutonium chemical compound is ingested, allowing the alpha particles to directly radiate internal organs. Because of this, they should have AT LEAST been wearing respirators of some sort; just in case.



Absolutely insane hysteria and mythology has surrounded nuclear weapons since their inception. It is a curious phenomenon--one that I am devoting much time in the near future to investigating (also I want to dispel misconceptions). - February 9, 2010No Protective Gear

Subject: If it had... fdungan said, "Had it gone off, South Carolina would be uninhabitable even today due to radiation..."

Although it would have been an horrific disaster, actually this statement isn't true. The bomb was of a type with that of the Trinity test. Ground Zero at the Trinity site is safe to visit:

http://www.atomictourist.com/trinity.htm

Had it been an H-bomb, the area would have been unsuable for years, perhaps decades; but by this time it would remain only somewhat hazardous, and inhabitable with some precautions. The largest-ever US H-bomb test, at Bikini Atoll, was worst-case from a contamination standpoint; a ground explosion rather than an airburst. Bikini is now inhabitable, though with some hazardous residues that can accumulate in locally-grown foods:

It's easy to get shrill about nuclear hazards, easy (and justifiable) to be suspicious of official proclamations. Radiation and nuclear weapons are no small matter, but even so it's unproductive to engage in hysteria.

Incidentally... the bomb could not have gone "atomic" even if it had been dropped with its core, and it would have been possible to clean up the plutonium. The explosion would undoubtedly have broken it up, but it would not have been too widely dispersed. Removal of a not-unmanageable amount of surface soil in the area would have done the job.

The clip is a nice bit of history, I'm glad it's available here. said,Although it would have been an horrific disaster, actually this statement isn't true.

I'm actually producing a documentary on the Mars Bluff incident for the South Carolina Educational Television Network (The local PBS affiliate).



You mentioned that your uncle was the USAF Attorney. I would love to talk to you and if he's willing, interview him for the film. I can be reached via email at mburrows@

Subject: BORN THERE I was two when this happened and visited the site last week while there on vacation to see my family. A man bought the land and put a trailer park on it years and years ago but did not pay taxes. I don't have any idea why he didn't think he needed to, but there are dozens of bare areas where trailers used to be and abandoned electric and water meters amongst the pines. Wish I could upload the photos of it here. The sickest is that the old trailer park sign is still there next to a couple of government sanctioned standard green landmark signs that say "ATOMIC BOMB CRATER". The access road is called "Crater Road" and even sicker is an old bait and tackle shop sign. The shop was called "Leap of Faith Bait and Tackle".



While we drove through the abandoned park, we observed surveyors there, no idea what they are going to do, a museum perhaps? I just remember thinking as I found out about it as a kid as I played with friends who lived in Mars Bluff how lucky we were to be alive. - July 8, 2008BORN THERE

Subject: Responses to comments Just a quick response to the comments below:

zenaris -- Hiroshima and Nagasaki are inhabitable and have many people living there today. You can even visit the place where the atomic bomb went off.

fdungan -- Actually it was an "ordinary atomic bomb" -- it was a Mark 6 plutonium implosion weapon, an improved version of the "Fat Man" bomb that detonated over Nagasaki. Even if it had had its plutonium core inside of it, it would not have detonated in a full nuclear explosion (it would have spread a lot of plutonium around, which would have been bad, but not as bad as a full-blown fission-driven explosion). It was not a thermonuclear weapon. There is no way in which its full explosive power would have left the entire state of South Carolina "uninhabitable." Perhaps you are confusing it with the Tybee bomb, which was a thermonuclear weapon, and was accidentally dropped in Georgia a few months earlier.



In terms of the misleading nature of the clip, the most egregiously inaccurate line is that this was "the first accident of its kind, in history." In fact, a number of accidental droppings and explosive (non-nuclear) detonations of nuclear weapons had occurred over the course of the 1950s. True, the EXACT circumstances of this "accident of its kind" had not occurred, but it's cutting a pretty fine line there, when most people hearing that are going to think that no accidents of dropping nuclear weapons out of bombers had occurred, when in reality all the line means is that no dropping of implosion weapons without their cores over inhabited civilian areas where the explosives then detonated had occurred.



Anyway, an interesting clip. - February 10, 2008Responses to comments

Contrary to what zenaris says, Hiroshima and Nagasaki are not inhabitiable. There are over 1 million residents of Hiroshima and more than 400,000 residents of Nagasaki. - August 18, 2006Somewhat interesting

Subject: "Dead" A-Bomb Hits U.S. Town An interesting newsreel and event. Maybe it's true that, had the bomb been armed and gone off, South Carolina would be uninhabitable even today - just as Hiroshima and Nagasaki are still uninhabitable. - August 2, 2006"Dead" A-Bomb Hits U.S. Town

Keep in mind that this was produced during the height of the Cold War. The Air Force did its best to minimize the danger. Neither the press nor the military wanted to alarm the public.



During this era, people in the know read between the lines. Today we tend to view this newsreel as a coverup, but at the time it was produced (the McCarthy era), it was par for the course.

Subject: An Important Bit of Atomic, South Carolina, and Automatic Manufacturing/Computer Technology The first bit is about the bombing of Mars Bluff, South Carolina. A B-47 suffered an electrical fault and toggled off a nulcear gravity bomb through the bomb bay doors, severely damaging several homes and injuring several people. My uncle was the government lawyer that defended the US in the ensuing lawsuit, so there is some family folklore to go with this and thus a personal interest. BTW, I suspect that the "TNT" mentioned was newsreel-eese for "an unknown high explosive agent": I suspect that they use more sophisticated stuff in nuclear weapons than TNT, but that is just a hunch. I dont think the device had any nuclear material in it to speak of, and none was ever recovered in any event. It was a "live" weapon, but apparently had its core of plutonium (I assume) removed for the exercise.



The second bit was about one of the first NC (Numericaly Controled) automated manufacturing stations. This generation of early automated milling station used paper tape to store the programming that controls the selection of tools, speeds and feeds, motion of the workpiece and cutter, ect. When I was in the machine tool program at the local tec college years ago, we had a beheamoth like this (only made by GE) gathering dust in the corner. More modern machines using more flexible CNC (Computer Numericaly Controled) systems had long ago replaced it. This is the technology that bridged the gap between the manualy operatied mills, lathes and shapers of 100 years ago and the ultra-automated manufacturing stations of todays factories. Must-have footage in any discussion of modern manufacturing and the early impact of computers on the workplace. - May 8, 2005An Important Bit of Atomic, South Carolina, and Automatic Manufacturing/Computer Technology
