Looking for reference on decay randomness

Click For Summary

Discussion Overview

The discussion centers around the randomness of radioactive decay, referencing specific research that suggests variability in decay rates, potentially influenced by external factors such as solar activity. Participants seek to identify relevant publications and explore the implications of these findings.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant recalls reading about research indicating that the decay of a subatomic particle appeared random or unpredictable, particularly in low-level reactions.
  • Another participant mentions experiments suggesting that radioactive decay rates may vary with the time of year, while other studies have ruled out such variations with reasonable confidence.
  • A third participant references a specific case where the decay rate of manganese-54 was observed to dip before a solar flare, proposing that solar activity might influence decay rates.
  • A later reply strongly criticizes the claims made by researchers regarding the variability of decay rates, labeling them as unfounded and suggesting that the original experimenters would not support such conclusions.

Areas of Agreement / Disagreement

Participants express differing views on the nature of radioactive decay, with some suggesting variability influenced by external factors, while others firmly reject these claims as invalid. The discussion remains unresolved with competing perspectives on the randomness of decay.

Contextual Notes

Participants reference various studies and articles, but the specific assumptions and methodologies of the cited research are not fully detailed, leaving some aspects of the discussion open to interpretation.

Hello,
Sometime in the last 6 months I read that researchers analyzing data from the decay of a subatomic particle and reported that the decay appeared to be random or unpredictable. I recall they said this particular reaction was very low level. This would have been in either Science, Nature, Scientific American, or Science News. I have retired and access to them is difficult now.
Does anyone remember that publication?
I would like to learn more about this work and its significance. My typical search engine responses are too large to read in entirety and frustratingly full of junk. Any search suggestions would be appreciated.
Thank You,
Steve

As I recall some experiments had shown that the radioactive decay wasn't random but appeared to vary with the time of year. Other experiments ruled out any such variation to a reasonable confidence level...

Like you, I'm sure I've seen articles in the popular press on this subject but where?
 
Perhaps...

RADIOACTIVE materials decay at a predictable rate—so predictable, in fact, that scientists widely use them to date artefacts and geological objects. That, at least, is the received wisdom, which Jere Jenkins and Ephraim Fischbach, from Purdue University in Indiana, think may need revising. In 2006 Dr Jenkins noticed that the decay rate of the radioactive isotope manganese-54 dipped 39 hours before a solar flare came crashing into Earth's protective magnetic field. Now it seems that the sun might affect other types of decay, too.

That result is utter, complete and total rubbish.

Fishbach has a habit of re-analyzing other people's data and making claims that the people who actually did the experiment would not make.
