TLDR
In this article, the authors reexamined their previously published data to search for evidence of correlations between the rates for the alpha, beta-minus, beta plus, and electron capture decays of 22Na, 44Ti, 108Agm, 121Snm, 133Ba, and 241Am and the Earth?Sun distance.About:

Time-Dependent Nuclear Decay Parameters: New Evidence for New Forces?
Ephraim Fischbach,J. B. Buncher,J. T. Gruenwald,Jere H. Jenkins,Dennis E. Krause,J. J. Mattes,J. R. Newport +6 more
TL;DR: The question of whether nuclear decay rates (or half-lives) are time-independent constants of nature, as opposed to being parameters which can be altered by an external perturbation has been discussed in this paper.

Perturbation of nuclear decay rates during the solar flare of 2006 December 13
TL;DR: In this paper, the decay rate of 54 Mn was detected during the solar flare of 2006 December 13, whose X-rays were first recorded at 02:37 UT (21:37 EST on 2006 December 12).

Searching for modifications to the exponential radioactive decay law with the Cassini spacecraft
TL;DR: In this paper, the power output of the radioisotope thermoelectric generators aboard the Cassini spacecraft was used to test the conjecture that small deviations observed in terrestrial measurements of the exponential radioactive decay law are correlated with the Earth-Sun distance.
Journal ArticleDOI
Analysis of environmental influences in nuclear half-life measurements exhibiting time-dependent decay rates
TL;DR: In this article, a detailed analysis of the responses of the detectors actually used in the BNL and PTB experiments, and show that sensitivities to seasonal variations in the respective detectors are likely too small to produce the observed fluctuations.

Half-life of32Si
TL;DR: In this paper, the decay rate was determined from the 32Si/36Cl ratio of counts, based on the analysis of 53 points taken in 48 months, the valueT1/2 = 172(4) yr is adopted for the half-life of 32Si.

Half-life measurements of europium radionuclides and the long-term stability of detectors
TL;DR: In this paper, the authors used the half-life value of 152 Eu as a reference, and determined the time-dependent decrease of the efficiency of semiconductor detectors at different photon energies for periods of the order of twenty years.
