Detection of Trace Radioisotopes in Environmental-type Samples by Glow Discharge Mass Spectrometry
The possibility of the determination in soils, sediments and vegetations of some radioisotopes of caesium, strontium, plutonium, uranium and thorium by glow discharge mass spectrometry (GDMS) has been investigated. The preparation of the samples is described as a combination of the use of a conductive host matrix and a secondary cathode in order to decrease the dilution effect of the blending material for trace level determination and to have a stable discharge. Effects of interferences arising from the nature of the conductive host matrix and of the secondary cathode on the sensivitiy of the method are disussed. GDMS is shown to be a helpful technique for the determination of radioisotopes in environmental samples.
