The Saskatoon host locat ion will be the Saskatchewan Cyclotron Facility\, managed by the Sylvia Fe doruk Canadian Centre for Nuclear Innovation\, who continue to "...apply n uclear science in order to advance medical health and environmental sustai nability for the benefit of society..."\, and to recognize Dr. Sylvia Fedo ruk and other members of the scientific team in Saskatchewan.\nAbstract:\n The development and use of cobalt-60 cancer treatment machines made a sign ificant and positive contribution to health care worldwide. While X rays p roduced by X-ray tubes had been used for cancer treatment since the 1920s\ , their energy was not sufficiently high to achieve adequate and focused p enetration to deep-seated lesions in the body. Radium sources had been use d with some success but was very expensive. Dr. Harold Johns\, a Canadian medical physicist\, recognized that cobalt-60\, which could be produced in a nuclear reactor\, had a long enough half-life and emissions of sufficie nt strength to potentially replace radium. He provided the guiding force t hat led to development of a suitable source\, a machine to contain it\, an d a methodology and data to control it that were still required before thi s potential could be realized in a practical setting. Development and cali bration of a cobalt-60 radiation therapy machine proved effective for trea tment of deep-seated tumours\, and in 1951 two teams of medical physicists \, engineers\, and radiation oncologists in London (Ontario) and Saskatoon (Saskatchewan)\, independently\, yet cooperatively\, designed the first c obalt-60 radiation treatment machines or “cobalt bombs”. These machine s directed gamma radiation directly on cancerous tumours. The first use of the cobalt treatment was on 27 October 1951 at Victoria Hospital\, London . Decades of effective worldwide use and the many millions of lives extend ed have proven the efficacy of this technology and the benefit to humanity .\n\nCo-sponsored by: Sylvia Fedoruk Canadian Centre for Nuclear Innovatio n\, Inc.\n\nSpeaker(s): Denard\, Jeter\n\nAgenda: \n10:00 AM: Welcome - De nard Lynch\, MC)\n\n10:05 AM: Introduction - Milestone Committee represent ative from IEEE North Saskatchewan Section (Denard Lynch)\n\n10:15 AM: Rem arks - Representative from host organization from Sylvia Fedoruk Centre (J eter Hall)\n\n10:25 AM: Closing Remarks\, thank you's\, introductions and announcements (Denard Lynch)\n\n10:30 AM: Refreshments\n\nRoom: N/A\, Bldg : Saskatchewan Cyclotron Facility\, 120 Maintenance Road\, University of S askatchewan Campus\, Saskatoon\, Saskatchewan\, Canada\, S7N 5C4 LOCATION:Room: N/A\, Bldg: Saskatchewan Cyclotron Facility\, 120 Maintenanc e Road\, University of Saskatchewan Campus\, Saskatoon\, Saskatchewan\, Ca nada\, S7N 5C4 ORGANIZER:denard.lynch@ieee.org SEQUENCE:18 SUMMARY:IEEE Milestone Dedication: Cobalt-60 Radiation Cancer Treatment Mac hines\, 1951 URL;VALUE=URI:https://events.vtools.ieee.org/m/484454 X-ALT-DESC:Description: <br /><p><span style="font-family: helvetica\, aria l\, sans-serif\;">The Dedication Ceremony will establish an "<em>IEEE Mile stone in Electrical Engineering and Computing</em>" by the installation of plaques <span style="color: rgb(0\, 0\, 0)\;">commemorating</span> the de velopment and first uses of Cobalt-60 cancer treatment machines in Saskato on\, SK\, and London\, ON\, in 1951.&nbsp\; The Saskatoon host location wi ll be the Saskatchewan Cyclotron Facility\, managed by the Sylvia Fedoruk Canadian Centre for Nuclear Innovation\, who continue to "...<em>apply nuc lear science in order to advance medical health and environmental sustaina bility for the benefit of society...</em>"\, and to recognize Dr. Sylvia F edoruk and other members of the&nbsp\; scientific team in Saskatchewan.</s pan></p>\n<div><span style="font-family: Arial\;">Abstract:</span></div>\n <div><span style="font-family: Arial\;">The development and use of cobalt- 60 cancer treatment machines made a significant and positive contribution to health care worldwide.
