“…an extraterrestrial influence. Results, performed along similar lines, from field sites outside Israel [9,10] support the latter idea of an extraterrestrial influence. This serves as an indication that such influence operates at different locations on the Earth, at very different geologic scenarios and to a depth of hundreds of meters and even 1 km in the crust.…”

Radon (Rn-222; Rn) and Thoron (Rn-220; Tn) from the lowermost atmosphere in Arad, Romania, were investigated from 1993 to 2015. Daytime and night-time measurements exhibit (i) systematic differences; (ii) large annual variations; (iii) semi-annual and possibly ternary annual periodicities; (iv) amplitudes of the annual and semi-annual periodicities differ between daytime and night-time measurements. The day of year of the summer peak time (SPT) of the annual variation of composite Rn and Tn data depict smoothly covarying SPT patterns separated around 50 days. SPT patterns of daytime and night-time of Rn and Tn depict additional separations of gradually varying multi-year patterns. For both radionuclides, the night-time SPT precedes the daytime SPT—by around 105 days for Tn and around 60 days for Rn. In the case of temperature, the SPT of daytime and night-time measurements overlap at around day 195. Thus, for Rn and Tn, daytime and night-time differences depend on the time of measurement within the 24 h cycle. This implies that Rn and Tn measurements are influenced by the rotation of the Earth around its axis. It is suggested that these relations, observed in coexisting Rn and Tn, are a further indication for a solar (extraterrestrial) influence on nuclear radiation, previously suggested for radon.

Indications for influence of artificial (man-made) activity on radon signals, in simulation experiments

Radon (Rn-222; a radioactive noble gas) is characterized by large temporal variations that differ significantly from variations of (i) other trace elements in geogas (noble gases); (ii) variation patterns of other dynamic geophysical systems (atmospheric, tidal). Consensus exists that there is no simple and straightforward understanding of the phenomena and its behaviour. This lacuna in the understanding of the underlying principles hampers the development of applications—such as radon as a proxy of processes in the seismogenic context. Using results from field investigations and simulation experiments the GSI suggested that an unidentified extraterrestrial component, probably in solar radiation, drives periodic radon signals in the diurnal and annual frequency bands. Recent findings from experimental investigations shed additional perspectives allowing a new evaluation of the issue. Particular transient signals, measured with alpha and gamma detectors, are interpreted to reflect the influence of artificial activity. Criteria are (i) signals lasting several hours that occur around midday on workdays (Sunday–Thursday); (ii) signals composed of a train of around 10 strong pulses, each lasting less than 15 min, occurring within several hours once a week, from Wednesday afternoon/evening to Thursday morning. A first interpretation is that an unidentified artificial activity of some sort (industrial?) generates and emits an unidentified agent that reaches enhanced confined mode experiments at the GSI laboratory, which respond to the incoming agent in the form of radon signals. Developing the capability of identification of such an earth-bound source generating an influencing agent is a key step towards understanding of external influence on radioactivity of radon.

“…Taking this regime for obtaining a scaling exponent, the conclusion would be that the underlying process is non-stationary. In turn, the correct interpretation of this finding is that the dominance of the diurnal cycle -together with semi-diurnal cycle and other sub-diurnal oscillations -dominates this frequency range [8], and what is seen by the fluctuation function (similar as for the PSD) is essentially the superposition of broad spectral peaks corresponding to these oscillatory modes plus possible sidebands [66].…”

“…6). The latter finding is consistent with previous results demonstrating the presence of additional periodicities of about 12, 8, 6 hours, etc., in the Coimbra data [8] as well as other environmental radon records [64][65][66][67]. Taken together, the part of the spectrum between about 3 hours and 1 day should not be used for estimating a spectral slope associated with possible long-range memory, since it mainly reflects the presence of periodic components in the signal.…”
