A leak at a South African Nuclear Energy Corp. plant this month has caused a global shortfall in the supply of isotopes used in millions of medical procedures every year, including treatment and diagnosis of cancer.

“No production is currently taking place, leaving a big shortage in the international market,” Don Robertson, managing director of NTP Radioisotopes SOC Ltd, said in an e-mailed response to questions. NTP produces a quarter of the world’s medical radioisotopes, making it the second-largest manufacturer, he said.
