Physical characteristics of radioactive microspheres.
| Microspheres | Diameter (Mean) | Density | Approximative Number of Micro-Spheres Per GBq * | Activity Per Microsphere |
|---|---|---|---|---|
| 90Y-Resin | 32 μm | 1.6 g/mL | 13 × 106 | 50 Bq |
| 90Y-Glass | 25 μm | 3.3 g/mL | 0.4 × 106 | 2500 Bq |
| 166Ho-PLLA | 30 μm | 1.4 g/mL | 10 × 106 | 450 Bq |
* On the day of calibration (approximately). PLLA: poly-(L-lactic-acid).
