Objection - assumes facts not in evidence.
Okay, 14C actually is radioactive, but the even lower mass 13C and 12C are not. So it has nothing to do with being "smaller".
It's possible that by "smaller" you're referring to the neutron capture cross section: I doubt it, but it's possible. If so, then you should realize that what you're asking is basically "Why is something that's unlikely to capture a neutron (because it already has so many that it's actively trying to get rid of one) unlikely to capture a neutron (i.e. has a low neutron capture cross section)".

Is a gamma ray a natural ray?
Yes, a gamma ray is a natural ray. It occurs as a result of changes to atomic nuclei, and we most often see them (gamma rays) appear in radioactive decay.
Is gasoline radioactive?
Oil is not generally radioactive unless it was originally located near radioactive material when it was extracted. More often, it only becomes radioactive when exposed to or stored near radioactive materials post processing.
Is the atom left after decay often radioactive?

What must occur before a radioactive atoms ceases to undergo further radioactive decay?
A stable, nonradioactive atom must be formed.
Do the cells of hyphae often contain more than one nucleus?
Yes, some do. Filamentous fungi (PHYCOMYCETES) may contain multiple nuclei in a coenocytic mycelium.
Is a gamma ray a natural ray?
Yes, a gamma ray is a natural ray. It occurs as a result of changes to atomic nuclei, and we most often see them (gamma rays) appear in radioactive decay.
Can a radioactive object make another object radioactive when it touches it?
Mostly no, but it depends on the nature of the two objects. Radioactive objects are usually emitters of alpha particles (helium nuclei), beta particles (electrons), and/or gamma rays (high-energy photons). None of those will usually induce secondary radioactivity in other objects. However, if neutrons are emitted, they can often penetrate the nuclei in another object, and if successfully absorbed there, can produce an unstable (radioactive) isotope. Also, if the source radioactive object is producing radon gas as a decay product, that can also be absorbed by some materials and start generating radiation there. (This does not require that it be "touching".)
What is the activity of a radioactive substance?
any one or a combination of radioactive substances that gives off photons that are usually considered harmful to humans and other life forms

What counts radioactive material?
We often use a Geiger counter to detect and count the decay of radioactive material.

What is Perinuclear Halo?
often used for shrinking of the nucleus and condesation of chromatin. vaculated area often formed around the shrunken and pyknotic nuclei . shrinking of the nuclei include the membrane ...that`s why the term perinuclear!!
Why is the age of a gold ingot is often mentioned because Gold is not radioactive?
natural isotope of gold is 197 and he is stable element and not with radioactive decay why the gold ingot are often associated with age?
Whats the word for cells with many nuclei?
A cells with many nuclei is often called a syncytium. The normal cell structure for many types of fungi is a syncytium.
The atoms that remain after a nucleus disintegrates is?
smaller then the original atom and possibly radioative
Atomic and nuclear bombs?
What about them? They are the same thing: bombs that get their energy from the atomic nucleus. However there are two kinds: fission (breaking up large nuclei into smaller ones) and fusion (joining small nuclei into larger ones). The fusion type are often called thermonuclear because it takes very high temperature to ignite the reaction (about 10 million K).
What must occur before a radioactive atoms ceases to undergo further radioactive decay?
A stable, nonradioactive atom must be formed.
