Question

what is radioactivity???​

Answer 1

Answer:

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.

Answer 2

Answer:

Radioactivity is simply when very small particles in objects emit energy or smaller particles. The energy that is produced can result in cancer, serious environmental damage, or helpful technologies. There are different degrees of radioactivity, and different exposures increase the harm it can cause.

Explanation:

Radioactivity is the spontaneous emission of radiation in the form of particles or high energy photons resulting from a nuclear reaction. ... For example, a light bulb may emit radiation in the forms of heat and light, yet it is not radioactive.
