Abstract Objective To ensure the health of staff engaged in tritium,the purpose of experiment is to find out a fast,convenient and reliable sample preparation and measurement methods for such routine monitoring.Methods We use the conventional distillation decolorization and non-decoloration quenching correction methods dealing with urine sample,and then carried out the urine sample liquid scintillation measurements,statistical analysis between the two measurements.Results By using above two different methods of sample pretreatment,the results that we measure tritium in urine sample are not obviously differet in comparison.Conclusion The above two different methods can be used for nuclear facilities staff and staff related to conventional tritium detection.However,non-decoloration quenching correction method is simpler and less in time and manpower than the conventional distillation method in operation.It is suitable for a large number of samples prepared,measured,and analyzed in a short period of time.
