WebYttrium-90 decays by emission of beta particles, with a physical half-life of 64.1 hours (2.67 days).[1] The product of radioactive decay is non-radioactive zirconium-90. The range of beta particles in soft tissue (χ 90) is 5 mm. Radiation emission data for Y-90 are summarized in Table 3. Table 3. Principal Y-90 Radiation Emission Data Mean ... WebTheraSphere consists of insoluble glass microspheres where yttrium-90 is an integral constituent of the glass. Each milligram contains between 22,000 and 73,000 microspheres. Yttrium-90 is a pure beta emitter (physical half-life of 64.2 hours or 2.67 days) and decays to stable zirconium-90.

WebYttrium 90 (y-90) is a beta emitter and a valuable clinical tool in internal radiation therapy for treating liver tumors. y-90 has a short half-life (less than three days). Implanted in a patient’s tissue, it penetrates 2.5 mm, with a maximum range of 11 mm, which minimizes side effects to adjacent tissues. Write the y-90 -decay equation in which WebA series of determinations on the half-life of yttrium-90 have been made, resulting in an average value of 64.24+/-0.30 hours. Y 90 was separated from its Sr 90 mother by either … hardwood floor repairman
