RadSpheres - precision radioactive glass microspheres

RadSPHERES are glass microspheres which emit alpha, beta or gamma radiation either individually or in combination. They are available in a wide range of biocompatible glass compositions, e.g. silicate, borosilicate, aluminosilicate and borate. Where unique needs exist, such as bioabsorbability or bio-inertness, Mo-Sci Health Care produces microspheres made from specially developed glass compositions.

RadSpheres and Health Care RadSPHERES are used for: Radiation therapy for malignant tumors Medical research for radiation therapy Radioactive tracers and labels Radiation synovectomy Microdosimetry

Many radioactive elements with different half-lives can be selected to meet the desired radiation decay requirements.The glass microspheres are made radioactive by neutron activation in a nuclear reactor.

Properties of RadSpheres

• Radioactive half-life from 2.3 hours to several years
• Chemical durability from bio-inert to biodegradable

Mo-Sci Health Care manufactures RadSPHERES under the strict quality control procedures needed for biological and medical applications, and provides documentation required to satisfy FDA standards.

Glass microspheres of varying diameters, typically from 10 to 200 microns, can be supplied with a diameter variation of 5 to 10 microns or less. Quantities are available from a few milligrams to hundreds of kilograms.
