Abstract When verifying the validity of exponential-decay law through 137 precise decay rate measurement series at various nuclear laboratories, minor violations have been observed in shape annual cycles residuals with different amplitudes and phase shifts. The timing amplitude these deviations compared local weather data it appears that ambient humidity is highly correlated instabilities radioactivity measurements. In fact, when compensating for a linear relationship absolute air, most are no longer statistically significant. As result, can now be demonstrated even higher fidelity.
