Comparison of /sup 137/Cs concentrations measured after in situ absorption with those determined by bulk water analyses or calculated from /sup 90/Sr analyses
- Univ. of Delaware, Newark
Concentrations of /sup 90/Sr and /sup 137/Cs determined at Woods Hole Oceanographic Institution by bulk water analysis were compared with /sup 137/Cs concentrations determined at the University of Delaware following absorption in situ. Five groups of profiles from the North Atlantic were used. Bulk water values and in situ values were compared by plotting radioisotope concentrations against sigma/sub tau/ and comparing values, obtained by linear interpolation, at the same values of sigma/sub tau/. When compared with mean analytical uncertainties, data obtained by the two methods seem in excellent agreement. The systematic difference between analyses performed by the two methods appears to be close to 0.6 dpm per 100 liters.
