Searching for modifications to the exponential radioactive decay law with the Cassini spacecraft
TLDR
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.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.

Radiations from Radioactive Substances
TL;DR: In this paper, the authors provide a definitive account of the state of research into alpha, beta and gamma radiation in 1930, explaining the theory and process behind inferring the structure of the atom and the nucleus.

TL;DR: 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.

Half-life of tritium and the Gamow-Teller transition rate
TL;DR: The half-life of tritium implanted into a Si(Li) x-ray detector has been determined to be 12.03 yr by following the decay for about 5 years by using a recently determined \ensuremath{\beta}-decay end-point energy.
