The use of an ultra low level liquid scintillation counter with extremely low background, MCA technique, storage and software evaluation of pulse height spectra has given very low LLD's, the possibility of - and
-spectrometry to some extent and time saving optimization of counting conditions. Quick and very simple but yet accurate analytical methods could be worked out worked out for environmental measurements: Environmental levels of tritium,14C in several assimilation products,222Rn and226Ra in water without any sample pretreatment. Suggestions for possible further applications in environmenial monitoring and low level counting are given.
