The influence of the statistical error in radioactivity counting on the precision of isotope dilution analysis, III
- 27 Downloads
A slightly modified procedure of direct substoichiometric isotope dilution analysis is theoretically treated and its advantages are stated. The precision of one case of reverse isotope dilution is calculated, and tables for rapid calculation of optimum measuring conditions and of the resulting errors are given. The precision and optimum conditions are calculated for determining the count rate ratios of two radioisotopes present in a mixture using two instruments (absorbers), and pertinent tables are presented.
