The fluctuations appear to be very small but could lead to predictive tools for solar flares and may have an impact on medical radiation treatments.Almost three years ago, I wrote about how I had changed my mind on radioactive half-lives.Throughout my scientific education (from high school through graduate school), I had it pounded in my head that radioactive half-lives are constant."If the relationship between solar activity and decay rates proves to be true, it could lead to a method of predicting solar flares, which could help prevent damage to satellites and electric grids, as well as save the lives of astronauts in space," Jenkins said.
"Finding that the decay rates fluctuate in a pattern that matches known and theoretical solar frequencies is compelling evidence for a solar influence on decay rates." Jenkins and Fischbach collaborated with Peter Sturrock, a professor emeritus of applied physics at Stanford University and an expert on the inner workings of the sun, to examine data collected at Brookhaven National Laboratory on the rate of decay of the radioactive isotopes silicon-32 and chlorine-36.GNS provides a number of complementary age tracer methods to date water samples.
