摘要：

Naturally occurring radioactive materials in geologic and building materials have been recommended or regulated in most countries. Ra-226, Th-232 and K-40 are important radionuclides for building materials. Sometimes for radiation dosimetry, the activity of the radionuclides must be determined in short time. However, samples must be stored in measurement containers for 30 days for the determination of Ra-226 in traditional gamma-spectrometry. In this study, pair measurement-gamma spectrometry (PM-GS) method was studied to determine rapidly Ra-226 in geologic and building materials. The samples were measured two times within 7 days after sealing. The activity concentrations of Ra-226, Th-232 and K-40 in geologic and building materials could be successfully determined within a week by using the PM-GS method.
