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.

How did the discovery of radioactivity contradict Dalton's atomic theory?
radioactivity proves that there are smaller particles in an atom that makes it up, they are proton, neutron, and electron. Dalton's atomic theory clearly states that the atom is the simplest particle. Radioactivity contradicts Dalton's theory since it proves that there are particles which are simpler than the atom.
What is the most chemically reactive metal?
The most chemically reactive metals are the alkali metals. Francium is the most reactive of these and of all metal (although it is present on earth only in exceedingly small quantities, due to its radioactivity).The most reactive element available in useful quantities in Flourine.
Where does most sodium come from?
It comes from flowers
Is a majority of the world's electricity comes from water power?
No. Most of our energy comes from burning coal.
Is hydrofluoric acid soluble in water?
Yes, it certainly is. In fact, most commercial HF comes as a solution of 40 wt% HF in 60% H2O. Pure HF would be a gas at ambient pressure and temperature (similar to HCl). Please be aware that HF is really one of the most dangerous substances you can encounter in a usual lab.
Where does most of the radioactivity that you personally encounter come from?
The radioactivity that people encounter on a regular basis actually comes from their natural environment rather than the radioactivity being from some manmade source.
Where does most of the radioactivity we personally incounter come from?
The sun.
In what kind of environmental are you most comfortable?
depends on the person its comes down to personally opinion
Which type of radioactivity would be most dangerous if you were exposed to it from a source outside of your body?
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.
Is radioactivity man made?
No, most radioactivity is naturally occurring.
Which particle is most massive in radioactivity?
You think probable to alpha particles.
What do you think were the most important long term consequences of Columbus encounter in America?
Disease was the most important long term consequence of Columbus's in America. This comes from trading in sex slaves.
Which organelle or cell structure would you expect to contain the most radioactivity after a DNA Synthesis?
That one The structure that would contain the most radioactivity would be chromosomes, because chromosomes are made up of DNA.
What type of power plant most exposes us to radioactivity coal or nuclear plants?
nuclear plants because the fission reaction releases lots of radioactive particles causing radioactivity..
The form of radioactivity that penetrates matter most easily is?
gamma radiationA2 perhaps neutrons.
What is the origin of most the radiation of encounter?
Our Sun
When do you encounter analogies most often?
In essays
