Table 5. Average percent correction made for fission product interferences during INAA (instrumental neutron activation analysis) of eight Argonne Premium Coal samples.
[Apparent concentration of each fission product is given in micrograms per gram µg/g) per µg/g of U. <0.1 indicates a correction of less than 0.1 percent was made. Data for individual splits have been reported by Palmer (1991)]
| Fission product Apparent concentration |
131Ba (1) |
140La (1) |
141Ce 0.27 |
147Nd 0.17 |
153Sm 0.00008 |
| UF PC-1 | 4.9 | 0.1 | 1.2 | 20.6 | <0.1 |
| WY PC-2 | .6 | .2 | 1.5 | 2.8 | <.1 |
| IL PC-3 | 16.1 | 1.0 | 8.2 | 26.8 | <.1 |
| PITT PC-4 | 3.4 | .1 | .9 | 2.7 | <.1 |
| POC PC-5 | .9 | .1 | 1.2 | 2.5 | <.1 |
| UT PC-6 | 7.1 | .4 | 4.0 | 25.0 | <.1 |
| WV PC-7 | 3.8 | .1 | 1.3 | 2.2 | <.1 |
| ND PC-8 | .1 | .3 | 2.7 | 22.9 | <.1 |
1Apparent concentration of element in µg/g per µg/g of U is
time dependent.
2Correction made on upper limit value.
