Yes it does. By the time a radon nucleus has decayed to a stable lead nucleus 6 alpha particles have been emitted. These are dangerous to health. For this reason, basements which are in high radon areas should be positively vented to the outside.
Note. care should be taken with decorative granite counter-tops. Some of these cause radon levels in the kitchen which are far above the safe limit.
No, radon is a chemical element. It decays primarily through alpha decay.
Thorium (and all compounds) is an alpha emitter; the energy of alpha rays is 4,477 MeV.
The most important radon isotopes (including 222Rn) emit alpha particles.
none
Naturally occuring Radon gas decays by alpha particle emission. However, many of the decay chain products have very short half lives, of which some decay by alpha particle emission and others by beta particle emission.
You are probably thinking of Radon, which is a gas.
The answer sought here might be ionizing radiation. Ionizing radiation comes in a couple of "flavors" as we know it. One is particulate radiation, and it involves a particle of some kind. The other is electromagnetic radiation, and it involves a "ray" or the like. Radon undergoes what is called radioactive or nuclear decay. 222Rn, the isotope of concern with radon, emits an alpha particle to decay. The alpha particle is two protons and two neutrons - a helium nucleus. This particle has very poor penetrating power. A sheet of paper will stop it. But radon is an inert gas, and if a person breathes in radon, even in small quantities, the alpha decay of radon in the lungs exposes soft tissue to terrible biological damage from the alpha particles. What's worse, the radon becomes polonium - another radioactive substance. Radon that is inhaled and undergoes radioactive (alpha) decay in the lungs has 7 more radioactive decays to go before becoming a stable isotope of lead. And each decay event further exposes local (and the same) tissue to heavy biological damage. Radon causes more lung cancer than most individuals know about.
No, exposure to radon gas, even a large amount, won't give you a headache. Radon is an inert or noble gas, and it is radioactive. Radon exposure is a bad thing as it is the second most common cause of lung cancer. But you won't be able to detect radon by any of your senses, and it will not directly cause you to be "sick" or for a "migrane" to appear. It will, after time, cause cancer because the radiation damage your lungs get from the long exposure. In the mean time, you won't feel a thing. At least not because of an exposure to radon gas.
What is the arguably the most common example of alpha decay is the alpha decay of radon-222. Radon-222 is an inert gas, and it appears as a result of the decay of naturally occurring uranium. It is a health risk. Radon-222 is a short-lived radioactive material (half-life of a bit over 3.8 days) that emits an alpha particle and becomes the element polonium. The equation looks like this: 86222Rn => 24He + 84218Po The 24He is the alpha particle, which is a helium-4 nucleus.

No, radiation is not gas, at least not the nuclear kind. Nuclear radiation is generally divided into two kinds: particulate and electromagnetic. Neither of them is gas. It might be argued that alpha radiation, which is the "release" of an alpha particle from an unstable atomic nucleus, produces a gas. That's because an alpha particle is a pair of protons bound to a pair of neutrons, and this is a helium-4 nucleus. But radiation is not generally considered a gas..answer 2 perhaps you are thinking of Radon, which is a gas, but a different question.
The result is radon, atomic number 86. 226Ra - alpha particle = 222Rn (radon, a radioactive gas)

Radon is an odorless gas.

Background radiation is highest in Cornwall and Devon, where there is a high source of Radon that seeps up from the ground as a gas,
