The radioactivity that people encounter on a regular basis actually comes from their natural environment rather than the radioactivity being from some manmade source.

B. The sources creator could personally benefit from convincing people to accept his argument.
Radioactivity refers to the particles which are emitted from nuclei as a result of nuclear instability. Because the nucleus experiences the intense conflict between the two strongest forces in nature, it should not be surprising that there are many nuclear isotopes which are unstable and emit some kind of radiation. The most common types of radiation are called alpha, beta, and gamma radiation, but there are several other varieties of radioactive decay. Radioactive decay rates are normally stated in terms of their half-lives, and the half-life of a given nuclear species is related to its radiation risk. The different types of radioactivity lead to different decay paths which transmute the nuclei into other chemical elements. Examining the amounts of the decay products makes possible radioactive dating. Radiation from nuclear sources is distributed equally in all directions, obeying the inverse square law.

Gamma radioactivity would be the most dangerous because, unlike alpha particles that can be blocked by paper or skin, and beta particles which can be shielded by foil, gamma radioactivity would need a lead shield. Plus gamma radioactivity effects organic material.
No, most radioactivity is naturally occurring.
Everyone is constantly encountering radioactivity. I don't remember whether there is anything that the average person receives more radiation from than Carbon-14. Carbon-14 is a radioactive isotope of one of the most important elements for life, continuously formed in the upper atmosphere as radiation hits nitrogen and turns one of its protons into a neutron. It is in equilibrium in earth's system, being formed at the same rate as it decays, and its radiation is not harmful. Because the fraction of carbon atoms that are C-14 is pretty constant everywhere on earth, and has been for a very long time, it is a useful tool to date things containing carbon.
Not all of it, but most. Other energy may come from radioactivity within the planets, or kinetic energy from objects that come in outside of the solar system. Also small amounts of radiation can come from other stars.
You think probable to alpha particles.
That one The structure that would contain the most radioactivity would be chromosomes, because chromosomes are made up of DNA.
nuclear plants because the fission reaction releases lots of radioactive particles causing radioactivity..
