Solubility of various radionuclides from simulated fallout particles (from LeRoy et al., 1966).
| Particle characteristicsa used in the study | Soluble fraction leached out in 0.1 N HCl (or 0.1 N NaOH) | ||
|---|---|---|---|
| 85Sr | 134Cs | 133Ba | |
| Local fallout simulated particles: | 0.06 | 0.01 | 0.05 |
| Microspheres of fabricated glass particles containing carrier-free tracers, where 10% of activity could be leached out in dilute HCl | (0.08) | (0.05) | (0.07) |
| Distant location fallout simulated particles: | 0.72 | 0.38 | 0.91 |
| Fabricated particles containing carrier tracers, Sr and Ba in oxide form and Cs as silicate. The mix was calcined at 1000° C, 50-100% of activity could be leached out in dilute HCl | (0.15) | (0.12) | (0.23) |
a
particle size ranged from 30-40 μm and particle specific activity was about 1.85 MBq per gram.
