It is, though the amount of energy is not usually enough to be effective as a source. There are a few cases where a self contained heat source is required where radioisotopes have been used to produce heat for a thermocouple device producing electric current, but only on a small scale for vital instruments.

Radioactivity
Becquerel discovered radioactivity while examining a piece of pitchblende wrapped in paper. He observed that the uranium-containing mineral emitted its own energy without an external source triggering it, leading to the groundbreaking discovery of natural radioactivity.
Radioactivity occurs when some of the binding energy in an atom becomes converted into kinetic energy, resulting in the expulsion of some of the particles of the atom. And generally some energy as well.
No, doubling the source of radioactivity will not halve the radiation intensity. Radiation intensity is directly proportional to the amount of radioactive material present. So doubling the source will double the radiation intensity.
Radioactivity is the term defined as the emission of energy from subatomic particles.
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.

Radioactivity is caused by unstable atoms, that break apart.
No, radioactivity cannot be canceled. Radioactivity is a natural process where unstable atomic nuclei release energy in the form of radiation. While the rate of radioactivity can decrease over time as the unstable nuclei decay, the process itself cannot be canceled.
