<Ciro Santilli> finds it interesting that radioactive decay basically kickstarted the domain of <nuclear physics> by essentially providing a natural <particle accelerator> from a chunk of radioactive element.
The discovery process was particularly interesting, including <Henri Becquerel>'s luck while observing <phosphorescence>, and <Marie Curie>'s observation that the <uranium> <ore> were more radioactive than pure uranium, and must therefore contain other even more radioactive substances, which lead to the discovery of <polonium> (<half-life> 138 days) and <radium> (half-life 1600 years).

{parent=Type of radioactive decay}
{wiki}

{synonym}
Most of the <helium> in the <Earth>'s atmosphere comes from alpha decay, since helium is lighter than air and naturally escapes out out of the atmosphere.
Wiki mentions that alpha decay is well modelled as a <quantum tunnelling> event, see also <Geiger-Nuttall law>.
As a result of that law, alpha particles have relatively little energy variation around 5 MeV or a speed of about 5% of the <speed of light> for any element, because the energy is inversely exponentially proportional to <half-life>. This is because:
* if the energy is much larger, decay is very fast and we don't have time to study the <isotope>
* if the energy is much smaller, decay is very rare and we don't have enough events to observe at all

<Uranium> emits them, you can see their mass to charge ratio under magnetic field and so deduce that they are <electrons>.
Caused by <weak interaction> TODO why/how.
The emitted electron kinetic energy is random from zero to a maximum value. The rest goes into a <neutrino>. This is how the neutrino was first discovered/observed indirectly. This is well illustrated in a <decay scheme> such as <image caesium-137 decay scheme>.
= Gamma ray
{parent=Type of radioactive decay}
{wiki}
Most commonly known as a byproduct <radioactive decay>.
Their energy is very high compared example to more common radiation such as <visible spectrum>, and there is a neat reason for that: it's because the <strong force> that binds <nuclei> is strong so transitions lead to large energy changes.
A <decay scheme> such as <image caesium-137 decay scheme> illustrates well how gamma radiation happens as a byproduct of <radioactive decay> due to the existence of <nuclear isomer>.
Gamma rays are pretty cool as they give us insight into the energy levels/different configurations of the nucleus.
They have also been used as early sources of high energy particles for <particle physics> experiments before the development of <particle accelerators>, serving a similar purpose to <cosmic rays> in those early days.
But <gamma rays> they were more convenient in some cases because you could more easily manage them inside a <laboratory> rather than have to go climb some bloody mountain or a <balloon>.
The <positron> for example was first observed on <cosmic rays>, but better confirmed in <gamma ray> experiments by <Carl David Anderson>.

{wiki}
The <half-life> of <radioactive decay>, which as discovered a few years before <quantum mechanics> was discovered and matured, was a major mystery. Why do some nuclei fission in apparently random fashion, while others don't? How is the state of different nuclei different from one another? This is mentioned in <Inward Bound by Abraham Pais (1988)> Chapter 6.e Why a half-life?
The term also sees use in other areas, notably <biology>, where e.g. <RNAs> spontaneously decay as part of the <cell>'s <control system>, see e.g. mentions in <E. Coli Whole Cell Model by Covert Lab>.

> There can, therefore, I think, be little doubt that what has been called <neon> is not a simple gas but a mixture of two gases, one of which has an atomic weight about 20 and the other about 22. The parabola due to the heavier gas is always much fainter than that due to the lighter, so that probably the heavier gas forms only a small percentage of the mixture.

* apply strong <magnetic field>, this separates the energy of up and down spins. Most spins align with field.
* send <radio waves> into sample to make nucleons go to upper energy level. We can see that the energy difference is small since we are talking about radio waves, low frequency.
* when nucleon goes back down, it re-emits radio waves, and we detect that. TODO: how do we not get that confused with the input wave, which is presumably at the same frequency? It appears to send pulses, and then wait for the response.

Those guys are really good, <Ciro Santilli> especially enjoyed their <quantum mechanics> playlist: https://www.youtube.com/playlist?list=PL193BC0532FE7B02C
The <quantum electrodynamics> one was a bit too slow paced for Ciro unfortunately, too much groundwork and too little results.

Videos licensed as <CC BY-SA>, those guys are so good.

These videos can give some geometric insight and do have their value.
But they are sometimes too slow, <how to teach and learn physics>[there are never any mention of experiments, just "the truth"].
And when things get "<mathy>", it sticks to a more qualitative view which may not be enough.
Very over the top with <sexy> demons and angels making appearances, and has some classic aesthetic artistic value :-)

Some insights, but too much on the <popular science> side of things.
