BSH
A substance used in a type of radiation therapy called boron neutron capture therapy. BSH is injected into a vein and becomes concentrated in tumor cells. The patient then receives radiation treatment with atomic particles called neutrons. The neutrons react with the boron in BSH and make radioactive particles that kill the tumor cells without harming normal cells. Also called sodium borocaptate.
