ANALYSIS METHOD AND ANALYSIS DEVICE OF RADIONUCLIDE IN SOIL SAMPLE IN ENVIRONMENT

摘要

PROBLEM TO BE SOLVED: To analyze and measure a volatile nuclide in an environmental sample without being disturbed by another nuclide, make the measurement and analysis efficient, save the time, and reduce the analysis waste.;SOLUTION: An environmental sample, for example a soil sample, is heated to about 1000°C to volatilize a volatile radionuclide. The volatilized radionuclide is introduced into an acidic and alkaline absorbent, and is collectively divided into nuclides ³H, ¹⁴C, ⁷⁹Se, ⁹⁹Tc(^99mTc), ¹²⁹I(¹³¹I), and ³⁶Cl. At least radionuclides ³H, ¹⁴C, ⁹⁹Tc(^99mTc), ¹²⁹I(¹³¹I), and ³⁶Cl are collectively analyzed.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
