A Flare for Radioactive Decay
It seems as if the rate of radioactive decay, long thought to be constant, is not so much. It seems to fluctuate with solar activity. In particular, it may provide what economists call a leading indicator for solar flares, to the benefit of satellite communications and astronaut safety.
The new detection technique is based on a hypothesis that radioactive decay rates are influenced by solar activity, possibly streams of subatomic particles called solar neutrinos. This influence can wax and wane due to seasonal changes in the Earth’s distance from the sun and also during solar flares, according to the hypothesis, which is supported with data published in a dozen research papers since it was proposed in 2006, said Ephraim Fischbach, a Purdue University professor of physics.
