DETERMINATION OF 151Sm IN SOIL SAMPLES BY USING LIQUID SCINTILLATION COUNTING METHOD
Известия Томского политехнического университета: Инжиниринг георесурсов, 2022 The relevance. One of the relatively long-lived nuclear fission products is 151Sm (T1/2~90 years). The total cumulative yield of 151Sm upon fission of the isotopes 235U, 239Pu and 238U is 0,46, 1,29 and 0,83 %, respectively. The estimated amount of 151Sm
