There are 3 types of radioactive materials and the answer to how each type is formed is complicated. To simplify the answer, I can say that some of them are formed in stars (and thus exist in nature, e.g. radium) and some of them are formed in either nuclear reactors or particle accelerators.
The most common element used in treating cancer is cobalt-60. This is produced industrially. Radium and uranium are widely used too (formed naturally). Another one is iodine-131 and it is used to treat thyroid cancer (industrial production too).
The force holding together is NOT gravity (too weak). It is NOT electric force either (actually electric force has a tendency to pull apart the particles composing the nucleus due to proton-proton repulsion, but it is relatively weak too). The force holding protons and neutrons together is called strong nuclear force (or just strong force), which is the strongest force in nature. Check this out:

The force between the neutron and proton and also between two protons and two neutrons inside the nucleus where they are held together is simply called as nuclear force. It is charge independent, short range and and 100 times stronger than the coulomb force of repulsion acting between two protons. Charge independent means the nuclear force between p and p, p and n and n and n are equal; short range means it acts only up to 10^-15 m and beyond that distance it becomes zero.

In the heart of a super nova or in the compression of matter on the surface of a neutron star the fusion of lighter elements take place crushing nuclei into unstable configurations that then undergo radioactive decay to achieve more stable configurations.

The force which holds Neutrons and Protons are Gravitational force of attraction and electrostatic force of attraction between neutron-positron neutron-muson etc In brief This forces are forces between subatomic particals.
And formation of elements is very complicated science. At this stage I cant answer this as am in 12th std. But I suggest you to not to weast time to find the answer of this question if you really not requried answer of this question.
