An Israeli company says it has developed a targeted radiation treatment that it claims can cure cancerous tumors.

“This is the first time in the world that you can treat solid tumors with alpha radiation,” Alpha Tau Medical’s CEO Uzi Sofer told the Times of Israel.

The technology called Diffusing Alpha-emitters Radiation Therapy, or DaRT, uses a needle to inject tumors with a radioactive seed that releases a high-energy dose of alpha radiation that destroys the tumor. The healthy tissue surrounding the tumors is left unharmed.
