Abstract

The SRS-05 radon-recording seismic station is widely used to monitor the volumetric activity of radon, primarily to detect its increase as an earthquake precursor. The low sensitivity of the sensor does not allow real-time recording of background volumetric activity of radon isotopes ²²²Rn (radon) and ²²⁰Rn (thoron). However, accurate measurement of background volumetric activity of radon isotopes is of great interest, especially in studies of ionization processes and the electric state of the near-surface atmosphere. This paper proposes a method for determining the mean background volumetric activity of radon isotopes based on α-spectra from a radon-recording seismic station over a long period (several days). The determined background volumetric activity of ²²²Rn and ²²⁰Rn in soil and near-surface atmosphere at the Borok Geophysical Observatory are presented.

Rad记录地震台站观测到的土壤和地表中of和Thor的背景体积活度

摘要

SRS-05 ra记录地震台站广泛用于监测of的体积活动，主要是检测detect作为地震前兆的增加。传感器的低灵敏度无法实时记录同位素²²² Rn（rad）和²²⁰ Rn（tho）的背景体积活度。然而，特别是在电离过程和近地表大气的电态研究中，accurate同位素的本底体积活度的准确测量尤为重要。本文提出了一种基于α谱地震台站长期（数天）的α谱确定determining同位素平均背景体积活度的方法。确定的背景体积活度²²²介绍了Borok地球物理观测台在土壤和近地表大气中的Rn和²²⁰ Rn。
