|Radioisotopes||134Cs, 137Cs, 90Sr, 106Ru, 103Ru, 144Ce, 147Pm|
|Detection by||alpha, beta, gamma||Description||
The following analytical scheme has been used for low level radionuclide analysis on 10 to 20 liters of seawater. It permits the separation and measurement of 134Cs, l37Cs. 90Sr, 106Ru, 2l9Pu, 240Pu, 147Pm and 144Ce.
The purification of the rare earth element fraction is based upon the separation of 147Pm from 144Ce by ion exchange and the use of stable Nd and Ce as yield monitors for 147Pm and 144Ce, respectively.
