John Mathieson of the United Kingdom, a long-time board member and fellow for the Waste Management Symposia, died June 7, at age 74 following a short battle with pancreatic cancer.
His death was announced Thursday by the WM Symposia organization, which sponsors the international nuclear conference in Phoenix. Mathieson had a career spanning more than 50 years in the nuclear industry, originally as a health physicist, and more than 30 years in international relations in the fields of spent nuclear fuel management, radioactive waste management, and decommissioning,” the Symposia said in a statement.
After retiring from the UK Nuclear Decommissioning Authority, Mathieson worked as a consultant at the International Atomic Energy Agency with extensive experience on projects across the globe, according to the WM Symposia.
A celebration of his life is scheduled for Monday June 15 at All Saints’ Church in Liddington, UK.
“John was more than a Board Member; he was a cherished friend and colleague,” said Symposia board chair Greg Meyer in the statement. “His vision, kindness, and ability to unite people from around the world left an indelible mark on our organization and on everyone fortunate enough to work with him. While we grieve this tremendous loss, we are deeply grateful for the legacy of collaboration and goodwill John leaves behind.”
