摘要：
The solubility of the aerosol “hot” particles, sampled in 1987 in the town of Pripyat, in the simulated lung fluid (SLF) (Gamble or Ringer solution) and in 0.1 M HCl was studied under static conditions. Leaching of radionuclides from the “hot” particles in the SLF decreases in the order 137Cs > 90Sr >> 239+240Pu ≥ 241Am, and in 0.1 M HCl, in the order 90Sr > 241Am >> 137Cs > 239+240Pu. The degree of passing into 0.1 M HCl solution for 90Sr and 241Am was estimated at 3.3-21 and 2.7-17%, respectively. Depending on the particle size, 0.06-2.2% of 241Am and 0.2-1.8% of 239+240Pu passes into the SLF within 28 days.
