Spectroscopy is the scientific tool that is based on how atoms absorb and emit electromagnetic radiation. Spectroscopy deals with how an object's light is dispersed into its component colors or energies.

oxygen made of molecules and atoms related to light and electromagnetic radiation has mass
Nothing with mass can travel at the speed of light, though it can get close. Nuclear fission (the splitting of atoms) does generate electromagnetic radiation which travels at the speed of light, but light is a form of electromagnetic radiation anyway.
Ionizing radiation is only one type of radiation. Visible light, for example, falls under the category of electromagnetic radiation. Radiation has many different detectable consequences.

The scientific name for radiation is "ionizing radiation." It includes forms of energy such as gamma rays, x-rays, and ultraviolet rays that have enough energy to remove tightly bound electrons from atoms, creating ions.
The process described is radioactive decay.
Well, to be honest, electromagnetic wave itself is never slowed down by anything and travels uniformly at the speed of light, c. However, when you look at macroscopic level, it is possible to slow down a combination of many many electromagnetic waves if they travel though a dense medium. The denser the medium, the more 'radiation' is slowed down. So slowing down process occurs when 'radiation' travels from less dense to more dense medium (the closed atoms are packed together, the more they absorb and reemit electromagnetic waves).
Ultraviolet radiation can rip electrons off the atoms to produce free radicals. However radiations of higher frequency can also have the same effect. The higher the energy of the photon of the electromagnetic wave, the easier it is for the photon to knock off electrons from an atom.
Ultraviolet. Most of the spectrum is invisible to people.
