Abstract
The rates at which 241Am and 239Pu are leached by triply distilled water from a candidate borosilicate glass 76-101 can be adequately correlated by the exponential, An = An0l−kt, where An is the concentration of the actinide in molar mass per square centimetre. The values for the parameters An0 and k are 2.45 × 10−9 M/cm2 and 0.024 ± 0.001 h−1, respectively, over the period of 1 to 24 h. When the glass samples are irradiated with gamma rays from a 60Co source of 1 Mrad/h, values of the parameters (1-to 24-h irradiation time) are A0 = 5.6 × 10−9M/cm2, k = 0.103 ± 0.004 h−1 for 239Pu and A0 = 2.2 × 10−11 M/cm2, k = 0.104 ± 0.003 h−1 for 241 Am.
