YANGON, Myanmar — Myanmar's military chief says the country plans to use nuclear technology for medical, research and energy purposes but will not develop atomic weapons, a statement that came a month after the government said it would declare any nuclear material in the country. State media on Saturday reported the comments made by the armed forces commander at the graduation ceremony for the military's Medical Academy. “In modern medical treatment, nuclear medicine is effectively used to treat cancer with radioactive isotopes and radioactive therapy," Vice Senior Gen. Min Aung Hlaing told the graduating class on Friday at a ceremony on Yangon. —AP
