Measurement of high-energy beta-or gamma-radiation

Measurement of high-energy beta- or gamma-radiation 

As high-performance column liquid chromatography has rarely been applied in inorganic radiochemistry, only a few papers can be cited to illustrate the combination of HPLC with radiometric detection in this field. The pioneering work of Horwitz et a1. shows the scope of high-performance column liquid-liquid chromatography with off-line radiometric detection in inorganic radiochemical and isotope separation. 

Low-energy beta-radiation can be detected by using scintillation techniques, described in Section 4.2. 

Several companies producing scintillation counting equipment, e.g., Nuclear Chicago, Intertechnique, Packard, Picker Nuclear and Beckman, offer flow cell conversion kits. Unfortunately, these cells and also those described in the literature discussed in the review papers mentioned above, have cell volumes from 0.5 to 4 ml, which makes them unsuitable for use in combination with high-performance liquid chromatographic columns. 

Beta-emitting radionuclides can be measured by homogeneous or heterogeneous scintillation counting using either the total eluate or part of the eluent stream.
