View Full Version : If you must play with nuclear fusion, use a big enough screwdriver

This was re-published today in our local paper honoring a Local boy Louis Slotin.

In spring 1946, Slotin had been working at the secret bomb-building compound of Los Alamos, N.M. for about 18 months.
On May 21, 1946, Slotin was asked to demonstrate a dangerous experiment known as "tickling the dragon's tail."

Ironically, "this would have been his last time doing the experiment," notes Zeilig, who wrote an exhaustive article about Slotin for
The Beaver magazine in 1995.
Slotin had done the table-top procedure dozens of times, to test the reactivity of a bomb core.
It involved gradually lowering one hemisphere of beryllium-coated plutonium onto another.
He had to bring them close enough to start a fission reaction without allowing them to touch and awaken the dragon's wrath.
With his right hand, Slotin was using a screwdriver to hold the hemispheres wedged apart.
His left hand grasped the upper hemisphere. A Geiger counter clicked faster and an instrument graphed the reaction rate in red ink as "criticality" approached.
It seems incredible today that anyone would perform a nuclear test with a screwdriver. But the intense Slotin had been taking such extraordinary risks since his days in Chicago.
He had a reputation as "a bit of a cowboy," says his nephew, Winnipegger Israel Ludwig.
"They cut corners," says Ludwig.
And Slotin may well have been recruited for the Manhattan Project because of his nervy attitude.
At 3:20 p.m. on that fateful day, with seven colleagues present in the lab, Slotin's screwdriver apparently slipped.
The two halves touched and "went critical" with a blue glow and a burst of heat.
The "bomb putter-togetherer" had given himself a fatal dose of radiation.
Since he was standing nearest to the apparatus, he absorbed most of the impact.
He died nine days later of horrific radiation sickness, blistered and swollen as if he had been standing 1.4 kilometres from a nuclear bomb blast.
The other seven men survived, though according to a 1989 story in the New York Times Magazine, at least three of their eventual deaths were linked to the radiation

Thanks Al, I'll keep that useful bit 'o info filed in the apporiate file. :) Interesting how things went back then.. I wonder if they still do it that way today? :D

It's a good reminder to look a that the things we've 'always done that way' and see if there is anything there that might relate to something like this. [ Don't tell anyone but I climbed a forklift mast the other day.. need a dim.. ~14' up.. didn't have time for the man basket.. stupid.. yes.. wasn't thinking about the 13mo old back at home.. depending on my getting through the day in 1 pc..]

Sometimes you get a second chance to 'live & learn', sometimes that isn't the case..
