BURSTS OF COUNT RATE OF BETA - RADIOACTIVE SOURCES DURING LONG - TERM MEASUREMENT (2005) (pdf)
When scanning the celestial sphere by a reflecting telescope with a radioactive source 60Co at the focus, bursts in the count rate were registered. The probability of their registration depended on the orientation of the telescope.
The number of bursts in a day as well as its connection with the orientation of the telescope were not reproduced in a unique manner. There were registered as single bursts with duration of about 1 second and an increase in the count rate up to three orders of magnitude, so more prolonged (up to several hours) events that consisted of short bursts of various amplitude distributed in time in some complicated manner.

EFFECT OF RADIOACTIVITY DECREASE. IS THERE A LINK WITH SOLAR FLARES? (2010) (pdf)
Results obtained with multichannel installation created for long-term studies of various processes, are collated with the data published by J.H. Jenkins and E.Fischbach, who found a decrease of 54Mn radioactivity near the time of series of solar flares between 5 and 17 December 2006. Analysis of the data from our installation in December 2006 has not revealed any deviations from the usual behaviour of the count rates for 90Sr-90Y, 60Co and 239Pu sources. The same can be said of the data collected during the period of highly powerful solar flares between 19 October and 4 November 2003. Apparent drops in the count rate were detected between 10 and 12 May 2002 while registering the activity of 60Co and on 19 and 20 June 2004 for 90Sr-90Y source. Around the time of these events, no observations of large solar flares were reported. Thus, proposed link between the drop in the rates of radioactive decay and appearance of solar flares could not be confirmed. From obtained outcomes follows, that the radioactivity drop effect, if it really exists, is rather rare, and that the reason calling this effect unequally influences various radioactive sources.

INFLUENCE OF RELIC NEUTRINOS ON BETA RADIOACTIVITY (2010) (pdf)
Results of calculations of distribution and motion of dark matter are presented. Considering neutrino as one of the components of dark matter and taking into account peculiar features of the interactions of slow neutrinos with matter, allow to make the conclusion that they may have tangible manifestations not only in the depths of the Universe but also on the Earth. Experimental results confirming predicted effects are described, including periodic variations of the beta radioactivity as well as count rate bursts for a beta radioactive source placed at the focal point of a parabolic mirror. Based on the data of astronomical observations, estimates of the mass of the particles influencing on beta radioactivity (about 20 eV) and their flux density (about 10^13 particles/cm^2 s) have been made. The discrepancy between our mass estimate and the 2 eV limit for the neutrino mass, established in the tritium experiments, is discussed.

PERIODS DETECTED DURING ANALYSIS OF RADIOACTIVITY MEASUREMENTS DATA (2010) (pdf)
Analysis results of data of long-term radioactivity measurements of 3H, 56Mn, 32Si, 36Cl, 60Co, 137Cs, 90Sr-90Y, 226Ra, 238Pu and 239Pu sources are presented. For beta-radioactive sources, their activity in addition to the exponential drop is characterized by rhythmic variations with a period of 1 year and magnitude of 0.1-0.35% from the average value. These oscillations attain maximum values between January and March, with corresponding minimum values occurring from July to September. Spectral analysis of 7-year long measurements of count rates of beta-radioactive sources 90Sr-90Y as well as 15-year long measurements of beta-gamma radiation of 226Ra revealed presence of rhythmic variations with a period of about a month and magnitude 0.01%. Magnitude of diurnal oscillations did not exceed 0.003%. Analysis of measurements data for alpha radioactive sources 238Pu and 239Pu did not reveal any statistically reliable periodic patterns. Possible factors underlying these rhythmic oscillations in beta-radioactivity are discussed.

DEVIATIONS FROM BETA RADIOACTIVITY EXPONENTIAL DROP (2011) (pdf)
At long-term count rate measurements of beta sources 3H, 56Mn, 32Si, 36Cl, 60Co, 137Cs, 90Sr-90Y and decay products of 226Ra the rhythmic changes with amplitude 0.1% 0.3% from average magnitude and period 1 year, and up to 0.01 % with period about one month are detected. Magnitude of diurnal oscillations did not exceed 0.003%. Analysis of measurements data for alpha radioactive sources 238Pu and 239Pu did not reveal any statistically reliable periodic patterns. Sporadic drops in the count rate were detected while registering the activity of 54Mn, 60Co and 90Sr-90Y sources. Bursts in the count rate were registered when scanning the celestial sphere by a reflecting telescope with 60Co or 40K radioactive sources at the focus point. Possible factors underlying these deviations in beta-radioactivity are discussed.

POWER SPECTRUM ANALYSIS OF LMSU (LOMONOSOV MOSCOW STATE UNIVERSITY) NUCLEAR DACAY - RATE DATA: FURTHER INDICATION OF R - MODE OSCILLATIONS IN AN INNER SOLAR TACHOCLINE (2012) (pdf)
This article presents a power-spectrum analysis of 2,350 measurements of the 90Sr/90Y decay process acquired over the interval 4 August 2002 to 6 February 2009 at the Lomonosov Moscow State University (LMSU). As we have found for other long sequences of decay measurements, the power spectrum is dominated by a very strong annual oscillation. However, we also find a set of low-frequency peaks, ranging from 0.26 year−1 to 3.98 year−1, which are very similar to an array of peaks in a power spectrum formed from Mt Wilson solar diameter measurements. The Mt Wilson measurements have been interpreted in terms of r-mode oscillations in a region where the sidereal rotation frequency is 12.08 year−1. We find that the LMSU measurements may also be attributed to the same type of r-mode oscillations in a solar region with the same sidereal rotation frequency. We propose that these oscillations occur in an inner tachocline that separates the radiative zone from a more slowly rotating solar core.
