Accuracy at time of placement was about 10m. The co-ordinates should put you at the plaque, and the cache is stashed in the nearby shrubbery (about 15 m as the gopher gallops)..
It looks like the nearby benches are a smokers' hangout. And of course there will be all sorts of passerbys, and construction workers during the day.
In 1951, here and in London Ont, scientists, physicists and physicians worked independently but co-operatively to design and develop the Saskatoon and Eldorado Colbalt-60 units. Both designs were prototypes for the first commercially available units called "Cobalt Bombs", which focused Gamma radiation on cancerous cells.
The radio-active cobalt, a small piece of metal about the size of four 25-cent pieces placed one atop the other, had been charged with X-rays or gamma rays in the atomic pile at Chalk River.
The small piece of radio-active cobalt of 1,500 curies, is the equivalent of 2,000 grams of radium which at its 1950's market would be worth about $40,000,000. It is also the equivalent of a 2,000,000 volt X-ray machine.
This small piece of metal was transported from the Chalk River plant to Saskatoon in a thick-walled lead container weighing a ton, a necessary precaution to protect its handlers from the deadly rays.
FTF prize is a $5 Tim's Gift Certificate Pack which was claimed by Bitzer.
