Work presented indicates that, with certain precautions, 224Ra based biomedical products can be used in a safe manner for the hospital staff and patients.
In vivo studies show that 224Ra-labeled CaCO3 microparticles could be safely administered in mice at therapeutically relevant doses and with a high degree of intraperitoneal retention.
The novel α-emitting microparticles have properties that make them a promising new modality for intracavitary cancer therapy.
