Ionizing radiation can be dangerous to living things, as it upsets the chemistry in living cells by breaking covalent bonds between atoms. Even if the radiation is not ionizing, such as in neutron flux, damage can be done there as well, due to activation processes that change the chemical identity of atoms.
Alpha radiation does not have a colour. In order for something to have a colour, it must emit rays of visible light. Alpha radiation and light are two different things which have little to do with each other.
Alpha radiation is not necessarily the "weakest" radiation. Alpha radiation is the emmanation of helium nuclei, which is two protons and two neutrons. As such, an alpha particle has a mass of 4 and a charge of +2. As a result, it interacts more readily than any of the other forms of radiation. This means that alpha can be stopped with a few inches or air, or even with a sheet of paper. That does not mean, however, that alpha is the least dangerous - if it is ingested, such as into the lungs, it will be in close proximity to sensitive tissues, making it one of the most dangerous forms of radiation. Its penetrating power is certainly the least, but, "weakest", not by a long shot.
Yes, alpha radiation is an ionizing radiation.
Generally no radiation is safe. You cannot "inject" radiation into anything because it is the product of various unstable nuclei decaying. Alpha radiation is much more ionising than gamma, but much less penetrating than it. That makes it more dangerous if it is inside your body; it can be stopped by skin. Therefore you would have to swallow a sample of a radioactive material. However, gamma radiation is always emitted together with alpha or beta radiation.
Radiation, even in small doses, can cause cancer in humans and other living things Alpha radiation is responsible for most of the damage of DNA in living cells
Alpha radiation cannot get pass through our body as it cannot penetrate through things. Beta can penetrate through things better than alpha. So if alpha is inside our body then it cannot get outside our body and therefore it becomes dangerous.
Any electromagnetic radiation can be dangerous. Alpha waves are higher on the radiation scale than x-rays so yes, they are dangerous.

alpha radiation
Radium emits alpha, beta, and gamma radiation. Alpha radiation is fully ionized helium nuclei. Beta radiation is high energy electrons. Gamma radiation is very high energy electromagnetic radiation. All of these can do significant damage to living things.

Yes, alpha radiation is an ionizing radiation.
Of alpha, beta and gamma radiation, gamma radiation has the greater ability to penetrate either shielding or living tissue. The penetration issue aside, a contact source that is an alpha emitter can do more tissue damage than beta or gamma radiation. Alpha and beta radiation are particulate radiation. They involve a particle. Gamma radiation is electromagnetic radiation of high energy. Use the links below to learn more about each type of radiation and get a handle on what's up.
A lot of things, but I think you might be referring to which form of radiation since this is the classic answer as to what would stop Alpha radiation. Furthermore tinfoil would stop alpha and beta radiation and lead would stop alpha, beta and gamma radiation.
Alpha, from outside the body, because alpha is stopped by the skin, a sheet of paper, or a few inches of air. From inside the body, however, alpha is one of the most dangerous forms of radiation.
