| Zusammenfassung |
| Systematic subsurface radon monitoring can be performed using nuclear techniques, either
with γ ray sensors based on scintillation crystals or with systems for detecting α particles.
This work addresses the comparison of radon measurements obtained simultaneously with γ
and α detection systems at the Bloch geophysical observatory, an horizontal deep tunnel in
the Amran massif, southern Israel. High-quality measurements at 15-minute temporal
resolution and spanning a period of several years are examined. At the daily scale the radon
concentration as evaluated from γ emissions follows the concentration from α particles with
a delay of 45 min. For time scales longer than 1 day, the temporal pattern recovered
by the γ and α sensors is very similar. However, on shorter time scales (up to 8
hours), marked differences are found in the variability structure of the γ and α time
series. |
