The non-destructive method for the plutonium isotopes content determination in environmental samples is developed. The proposed method is based on the measurement of the characteristic X-rays accompanying the decay of these radionuclides. The proposed method's error limits are 10–15% for samples with activity above 100 Bq and 15–20% for hot sampl
