The northeastern part of India is seismically very active due to the ongoing Indian Plate
under-thrusting and rise of several mountain ranges. As a result, the Himalayas, Naga Hills …

A long-term measurement technique of radon exhalation rate was previously developed
using a passive type radon and thoron discriminative monitor and a ventilated type …

Long-term monitoring of Rn-222 and CO2 at a depth of several dozen meter at the Sde-
Eliezer site, located within one of the Dead Sea Fault Zone segments in northern Israel, has …

The basis of short-term earthquake prediction is the identification of reliable precursors.
Anomaly of radon concentration escaped from groundwater (C Rn) is often used as a …

Radon‐in‐air monitor (RAD7, Durridge Co.) has been widely used to measure 222Rn in
water samples. RAD7 measures 222Rn via 218Po+ (t 1/2= 3.1 min), which is electrically …

The temporal variability of soil radon concentration of tectonically active origin is considered
a potential earthquake precursor. However, the reliable identification of radon anomilies …

Studies concerning 222 Rn emission from soils are growing interest in the Earth Sciences,
due to the gas potential as a tracer of natural phenomena. This paper presents a study of …

The 2012 Pollino (Calabria, Italy) seismic sequence, culminating in the Mw 5.2 earthquake
of 25 October 2012, is investigated, exploiting data collected during a long-term continuous …

The interest in the measurement of thoron (220 Rn) activity concentration in air has recently
increased, with the attention for the development of standards useful for the calibration of …

This paper describes the design of a low-cost radon detector that can easily be fabricated in
large quantities for the purposes of earthquake prediction. The described detector can also …
