Influence of Sun on radioactive decays?

In summary, the conversation revolves around a research paper on the influence of the sun on radioactive decay. There are doubts about the validity of the results and suggestions for further investigation. It is believed that there may be systematic effects that have not been accounted for.

Hi All,

http://arxiv.org/abs/1205.0205

Quite unbelievable!
Anybody knows what is going on with the research of this, are the results confirmed, propositions of the cause?

Hmmm "Influemce of Sun on radioactive decay" ? From the abstract it sounds more like their detector is picking up some extraneous signal, which looks plausibly related some solar phenomenon they haven't yet identified.

There are tons of things that vary every year, most notably the temperature (and they see a clear yearly trend in temperature). Even the line voltage shows some yearly variation (figure 5). An experiment deep underground, at the equator or in the southern hemisphere would be interesting I guess. Or at least heat the whole room with the experiment and see if it changes anything.

The inconsistency of the relative intensity of the daily cycle between day and night (GSI sees the opposite effect of other measurements) is a strong hint towards unaccounted or underestimated systematic effects.

Sure, it needs more investigation, but I would be surprised if it is a real effect.
 

Related to Influence of Sun on radioactive decays?

1. How does the Sun influence radioactive decays?

The Sun influences radioactive decays through its emission of high-energy particles, such as protons and alpha particles, which can interact with and alter the stability of atomic nuclei. This process is known as solar modulation and can lead to changes in the rate of radioactive decay.

2. Can the Sun's influence on radioactive decays be measured?

Yes, the Sun's influence on radioactive decays can be measured through experiments that use radioactive materials and track changes in their decay rates over time. These experiments have provided evidence for the influence of solar modulation on radioactive decays.

3. Does the Sun's influence on radioactive decays have any practical applications?

Yes, the Sun's influence on radioactive decays has practical applications in fields such as geology, archaeology, and nuclear physics. By understanding and accounting for the effects of solar modulation, scientists can more accurately date geological and archaeological samples and improve the precision of nuclear measurements.

4. Is the Sun the only external factor that can influence radioactive decays?

No, the Sun is not the only external factor that can influence radioactive decays. Other sources of high-energy particles, such as cosmic rays, can also affect the stability of atomic nuclei and contribute to changes in the rate of radioactive decay.

5. How does the strength of the Sun's influence on radioactive decays vary?

The strength of the Sun's influence on radioactive decays varies depending on the activity of the Sun and its distance from Earth. During periods of high solar activity, such as solar storms, the influence can be stronger, while during periods of low solar activity, the influence may be weaker.
