But that dip in the manganese-54 radioactivity was not a coincidental experimental fluke, nor was it the solar flare discombobulating the measurements, the Purdue researchers claim in a paper posted online (arxiv.org/abs/0808.3156).In West Lafayette the sun had set while X-rays were hitting the atmosphere on the other side of the globe, and the electrically charged matter that created electromagnetic disturbances worldwide was still in transit.The results were ignored by the scientific community.“People just sort of forgot about it, I guess,” commented David Alburger, the Brookhaven scientist who had conducted the experiment (Ibid).

Moreover, if solar activity was greater in the past, before humanity began measuring it, then the changes in radioactive decay might actually be greater than those measured by the scientists at Brookhaven, PTB, and Purdue.

Physicists are stirred by claims that the sun may change whats unchangeablethe rate of radioactive decay By Davide Castelvecchi November 22nd, 2008; Vol.174 #11 (p.

20) Physicists have responded with curiosity and skepticism to reports that the sun causes variations in the decay rates of some isotopes.

In one experiment, a team at Purdue University in West Lafayette, Ind., was monitoring a chunk of manganese-54 inside a radiation detector box to precisely measure the isotopes half-life. on December 12, 2006, the instruments recorded a dip in radioactivity.

At the same time, satellites on the day side of the Earth detected X-rays coming from the sun, signaling the beginning of a solar flare.

But if the change is real, rather than an anomaly in the detector, it would challenge the entire concept of half-life and even force physicists to rewrite their nuclear physics textbooks (Ibid.).
