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

Henri Becquerel lived in Paris, France for most of his life. He was a French physicist who discovered radioactivity in 1896.
MARIE CURIEPolish-born French physicist and chemist best known for her contributions to radioactivity.
Waves with longer wavelengths relative to the size of the obstacle they encounter will be diffracted the most. This is because longer wavelengths bend around obstacles more easily, allowing wave energy to spread out in all directions.
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.

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.

The nucleus would contain the most radioactivity after DNA synthesis, as this is where DNA replication takes place. The newly synthesized DNA would thus be housed in the nucleus, making it the organelle most likely to be radioactively labeled.

Some isotopes of elements are naturally radioactive, meaning they emit radiation spontaneously. However, humans have also created radioactive isotopes through processes such as nuclear reactors and weapons testing. So while radioactivity can occur naturally, it can also be man-made.
